To ensure the reliability and accessibility of fiber networks, network professionals need a more accurate, simpler and faster way to assess the integrity of the infrastructure. Therefore, choosing the right fiber testing tools is critical, not only to help professionals work efficiently and improve network reliability, but also help improve the reliability and value of the entire network. In this article, we will talk about how to choose a fiber optic OTDR. What is OTDR? OTDR stands for Optical Time Domain Reflectometer. It is a device for testing optical fibers. The device operates by sending a series of light pulses into the fiber and recovering light that has been dispersed or reflected back along the fiber point from the same end. It can be used to measure loss, optical distance and optical return loss on a fiber optic link. What an OTDR measures? Loss of splices ORL of link Reflectance of the connectors Total fiber attenuation Why You Need an OTDR? Fiber testing is an important operation for ensuring that the network is optimized to provide reliable and resilient services without fail. Here are two reasons why an OTDR is required. Service providers and network operators want to protect their investments in fiber networks. To authenticate their work, installers must use Optical Time Domain Reflectometer to perform bi-directional testing and provide proper cable documentation. Of course, you can use OTDRs to troubleshoot issues like break locations caused by dig-ups. Premises fiber networks have low loss budgets and little margin for error. As a result, installers must assess the overall loss budget with a light source and a power meter, which is a difficult task. While OTDR can quickly identify the sources of excess loss and confirm that splices and connections are within acceptable limits, it also saves time. Furthermore, it…

ONU converts fiber-based optical impulses to electrical signals. Individual subscribers receive these electrical impulses. Between ONU and the end user’s premises, there is usually a distance or other access network. ONU can also send, collect, and groom various sorts of data from customers and deliver it upstream to the OLT. Grooming is the process of optimizing and reorganizing a data stream to make it more efficient to provide. The OLT supports bandwidth allotment, which enables the smooth delivery of data float to the OLT, which is typically delivered in bursts from the consumer. ONUs can be connected using twisted-pair copper wire, coaxial cable, optical fiber, or wifi, among other technologies and cable types. 4/8 Ports POE Dual Band XPON ONU Why choosing this ONU?

Almost every network uses fiber patch cords. They are suitable for most network backbones because of their ability to transfer enormous amounts of data at rapid rates. Everything from data centers to laptops to cities and countries is connected by them. Patch cords made of fiber have become an important feature of enterprise data networks and telephony. This article will explain the differences between single mode and multimode patch cords in the hopes of assisting you in selecting the best fiber patch cord for your needs. What is fiber optic patch cord? Fiber optic patch cord, also known as fiber optic patch cable or fiber optic jumper, are one of the most significant components for connecting networks. They are meant to join or cross-connect fiber optic networks inside a structured cabling system. The fiber optic patch cord’s connectors on both ends make it simple to connect to optical switches, cable television, or other telecommunications equipment. There are a lot of fiber jumpers on the market right now. Fiber patch cord can be split into single mode fiber patch cord and multimode fiber patch cord based on different transmission media, and there are certain distinctions between them. What is single mode fiber optic patch cord? A fiber patch cord is a fiber optic cable capable of transporting only one optical signal. Single mode fiber optic patch cords are meant to enable broadband Internet connectivity and are used for high speed data transmission. Fiber optic cables with single mode fiber optic connectors on both ends make up the structure. Large scale connections, such as college campuses and cable television networks, are frequently used. What is multimode fiber optic patch cord? A multimode fiber patch cord is a fiber optic cable tthat can carry several optical signals and is used when various signals must be delivered over the…

A data center is a facility where a centralized organization shares IT operations and equipment, as well as a physical location where data is recorded and calculated. Businesses and other organizations use these facilities to store, disseminate, process and organize large amounts of data. Data centers are able to communicate between multiple sites on-premises and in the cloud. Key components of a data center design include switches, routers, SFP modules, cabling system, boxes and ODFs, storage systems, servers, firewalls, and application delivery controllers. Therefore, the security and reliability of the data center and its information is a top priority for any organization. Why data centers are important? Most businesses need to store data, and they store data on servers, which are like specialized computers connected to the business’s local network, usually to the Internet. However, as businesses and their needs grow, more servers and space are required. So at this time, a data center is needed to store the data in a secure facility. The Role of the Data Center A data center is an integral part of an enterprise, designed to support business applications and provide: data storage, management, backup and recovery; large e-commerce transactions; big data, machine learning and artificial intelligence services. Virtually every company and government entity sets up and maintains its own data center, or has access to someone else’s data center. Renting servers at co-location facilities, using data center services run by other parties, and using public cloud-based services from other organizations are also options. Types of Data Centers Enterprise data centers Managed services data centers Colocation data centers Cloud data centers The Standards for Data Center Tier 1- It is the most basic type of data center and needs to include a UPS.

This article will explain the difference between PLC Splitter and FBT Splitter and how to choose the right fiber optic splitter.

Direct current and alternating current are transmitted through power cords. They’re made of copper wire that’s been wrapped in insulating material and then covered in a non-conductive protective layer. Power cords are connectors that connect mains power to devices via wall sockets or extension cords. Almost anywhere that requires AC power, power cords are used. As a result, selecting an appropriate power cord is critical; this article will help you comprehend the power cord. What is a Power Cord? A power cord is a main or line cable with two connection couplers on both ends. Both ends of the power supply and gadget are detachable. It takes on the responsibility of temporarily connecting portable equipment to the mains power cord and can pass through a wall outlet or extension cord with ease. The power cord assembly is made up of three primary components. The first is the cable plug, which is also a male connector that provides electricity when plugged into an AC outlet. On the opposite end, there’s the container. The female connector that connects to the device is known as the receptacle. The main component is the wire, which is made up of insulated wires of various lengths and thicknesses. A power cord’s voltage rating, or kilo volts, determines how much power it can transmit. The gauge and length of a power cord determine its load capacity. The amount of current a power cord can carry and whether it will heat up is determined by its thickness or diameter. The voltage drop, or the amount of voltage lost from the connector to the power cord’s end, is determined by the its length. The voltage drop increases with the length of the power cord. Power cords are available in a variety of lengths, colors, and connector types to accommodate a variety…

Nowadays, there are many different brands of OLT and ONU in the market, such as Huawei, ZTE, Fiberhome, Baudcom, and many other brands. If you only have OLT or ONU, but want to use it with ONU or OLT, will you still choose the brand you use? If you have OLT or ONU in hand, but you bought ONU or OLT of different brands, are they compatible? This article tells you the answers to these questions.   Compatibility of Different Brands OLT and ONU The manufacturing technology of OLT and ONU has evolved as a result of the ongoing reform of human technology. The goods’ manufacturing specifications are nearly identical. OLTs are developed based on a standard protocol and can be interconnected. But why are some big brands of OLTs not compatible with other brands of ONUs? This is because they do not completely follow the standard protocol, or in other words, they add some protocols in the production of OLT to limit the compatibility of their own brand of OLT with other brands of ONUs, which is also an action to protect their own interests. Generally speaking, ONUs are not compatible with OLTs, many of which are incompatible due to restrictions imposed on OLTs. Why do people not choose the same brand of ONU adapter after buying the famous OLT? The main reason is that the price of OLT is already very expensive. If you continue to buy ONUs of the same brand, the budget will be very high. If you choose other brands of ONU, you can greatly reduce the cost. Of course, this also depends on the ONU being compatible with the purchased OLT. Baudcom ONU is Compatible with Other Brands OLT As a result, the OLTs of certain manufacturers may be compatible with the ONUs of other…

Fiber drop cable, choosing the right type of drop fiber cable and the appropriate termination method during the FTTH network installation is crucial to build a good FTTH structure. How to choose the right fiber drop cable? How to install fiber drop cable?

Fiber Cleaver is an extremely essential equipment used in the optical fiber field for low reflectance and low damage fiber optic splices, particularly when using already polished connectors with internal splices. But before giving a better and broader definition and clean explanation about this equipment it is important to understand what is cleave and what is the cleaving process, to understand better why is the fiber cleaver important and why we need it. Cleave In the optical fiber field, cleave is an intentional and calculated break, with the intention to produce a completely perfect flat end face and perpendicular to the optical fiber axis or with well defined angle against the optical fiber axis. This sufficiently perpendicular and planar fiber end face can be achieved via the fiber cleaving process. Cleaving process The cleaving process is the standard method used to precisely break(cut) an optical fiber for termination or splicing. It begins with making a really small fracture on the side of the optical fiber, with a sharp diamond, or carbide, before or while some defined tension is applied to the optic fiber. This causes the fiber to break, starting at the mentioned fracture point: the fracture quickly propagates over the full optic fiber cross-section. Often, the cleaving leads to a very clean surface of the obtained two fiber parts. The equipment that is mostly in the cleaving process is fiber cleaver. Fiber Cleaver Fiber cleaver is a device or equipment that detains the optical fiber cable under low tension, marking the surface in the appropriate place, and then applies a great amount of tension until the optical fiber fragments. Good fiber cleavers are usually automatic and give persistent outcome, regardless of the operator. When using a good cleaver, you basically just need to clamp the optical fiber inside the…

A fiber optic cable, also known as an optical-fiber cable or optical cables, is an assembly similar to an electrical cable, but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. Different types of cable are used for different applications, for example, long distance telecommunication, or providing a high-speed data connection between different parts of a building. Types of fiber cables ? FTTH (Fiber to the home) fiber optic drop cable FTTH (Fiber to the home) drop cable, the outer skin is generally black and white, the diameter is relatively small, and the flexibility is good; the cross section is 8-shaped, the reinforcing member is located at the center of the two circles, and the metal or non-metal structure can be used, and the optical fiber is located at the geometric center of the 8-shaped shape. The fiber inside the cable is mostly G.657A2 small bending radius fiber, which can be laid at a bending radius of 20mm. Fiber optic drop cables are available in many different types. The three most commonly used fiber drop cables include flat drop cable, figure-8 aerial drop cable and round drop cable. They are typically small diameter, low fiber count cables with limited unsupported span lengths, which can be installed aerially, underground or buried. As it is used in outdoor, drop cable shall have a minimum pull strength of 1335 Newton’s according to the industry standard. Because it small size and light in weight and good fiber optica cable price, the FTHH drop cable is suitable for application of fiber to the home. It can be out according to the distance of the site, increased…

What is SBC? A Session Border Controller is a specific hardware device that can be used to secure and direct the flow of IP traffic. Session Border Controllers are used in big business framework or any transporter network offering business private, business, fixed line or mobile VoIP services. It is commonly deployed on the administrator and enterprise side of the connection. The Session Border Controller is a network element that secures Session Initiation Protocol (SIP) -based VoIP. VoIP and SIP services use SIP to start, maintain, and halt their operations. SBC’s main goal is to improve connection while also addressing security problems. A session border controller is used to control a user’s IP communication session. SBC was designed to control VoIP networks, but they are increasingly used to control many types of online communication, including VoIP, text, video, and other collaborative formats. SBC-Session Border Controller What is VOIP? VoIP stands for Voice over Internet Protocol, which allows anyone with an Internet connection to make phone conversations. It’s a technology that lets you to make voice calls over the Internet rather than over a traditional phone line. With the rise of broadband, VoIP has become the preferred method of communication for both individuals and enterprises. Why do you need Session Border Controllers? Security The SBC functions similarly to a firewall or router, with the controller serving as the network’s gatekeeper. All calls or conversations will be monitored by an SBC at the “network boundary.” The controller not only monitors each connection, but it also determines and only enables authorized sessions to take place. Other media streams, such as video conferences or webinars, are included in sessions. Only permitted information is connected and transmitted over the network via one of these interworking technologies, which helps to block unauthorized traffic. Connectivity The SBC’s main function is to connect a company’s…

Any plastic or glass conduit used to carry light is referred to as an optical fiber. Although the theory behind it is relatively old, it has become a very essential technology in recent years as communications infrastructure has begun to use this fiber to carry data at extraordinarily high rates. Fiber optic communications, on the other hand, offers a wide range of uses in medicine, consumer products, and other fields. High-definition television signals are sent using fiber optic cables. Fiber optic cables offer many advantages over traditional metal wires, the most important being that signal degradation is greatly reduced. Additionally, it is immune to electromagnetic interference, which can severely hinder the transmission of data along normal metal wires. This also adds an extra measure of safety, as the fiber can withstand electromagnetic pulses that can damage metal cables. What is Glass Optical Fiber? Glass fiber is an optical fiber made of glass. Glass fiber optic cables consist of tiny strands of glass that are durable and high temperature resistant, but less resistant to flexibility and accidental breakage. Since glass cores are efficient at transmitting light, significantly increasing the transmission speed, they can be used for long sensing distances. This type of fiber is often ideal for harsh environments, as it can function properly even when subjected to mechanical stress, high temperatures or chemicals. Advantages of Glass Optical Fiber Applied to longer distance transmission Durable and high temperature resistant High transmission speed Less losses Can be used in corrosive and wet environments or even vacuum environments Disadvantages of Glass Optical Fiber More fragile and easy to break What is Plastic Optical Fiber? Plastic optical fiber, also known as polymer optical fiber or POF, is a type of optical fiber that is constructed of plastic rather than glass. PMMA (acrylic) fibers with a silicone resin…

With the rapid development of society, there is a growing need for people to communicate with others on the internet. Therefore, the requirements for communication equipment are also getting higher and higher. Fiber converter, a important but unfamiliar word, begin appearing in people’s life. So, what is fiber converter ? What does it work ? How to choose the right one ? Don’ t worry, you would find the answers after reading this essay. What is Fiber Media Converter? Fiber converter receives electric signal, and then converts electric signal into optical signal, or converts optical signal into electric signal. Actually, it just likes a container which allows optical signal and electric signal to convert internally. Without it, people would not be able to log on to the website and go online. As we all know, people use electronic equipment to achieve electronic communication in the past. However, there is a great limitation on converting electric signal that it does not work on long-distance communication. The appearance of fiber converter has greatly remedied this deficiency. Fiber Optical Media Converter Category As a vital modern communication equipment, Fiber converter can be divided into four categories. The first category is divided by the quantity of optical fiber. There have two modes, the single fiber converter and the dual fiber converter. The single fiber converter can receive and transmit electronic data through one optical fiber. The advantage of it is that it only needs one fiber-optic cable that can save lots of material.    So the single fiber converter usually apply to district where fiber-optic resources are insufficient. The shortage of the single fiber converter is that there is not a common standard of production, which probably lead to some confusion when different brands mingle. Similarly, the dual fiber converter has two optical fibers, one…

Indoor fiber optic cable is probably fairly familiar to us, as it is a necessary element of our daily lives. However, there are other aspects to consider when installing outside fiber optic cables. Outdoor optical cables are designed to work in a variety of conditions. We will talk about five types of outdoor fiber optic cable and the applications of fiber optic cables in this article. Aerial Outdoor Cable Aerial outdoor fiber optic cable is a fiber optic cable suitable for use in ducts and overhead installation points. Aerial optical cables are usually used for external installation of utility poles. Since the existing overhead pole lines can be used for installation, the laying method is very simple, thereby saving more construction costs. Aerial cables are mainly used in flat terrain, so they are easily affected by natural disasters such as typhoons, ice, floods, etc., and are also easily affected by external forces, so their quality must be very good to avoid frequent failures. Armored Fiber Cable Outside plant applications require armored fiber cable. To keep rodents out, they usually contain metal armor between the two jackets. It can bear crush loads, making it suitable for direct burial applications or data centers where cables are run beneath the floor or in dust and air. Because armored cables are conductive, they must be grounded appropriately. Loose Tube Fiber Cable Multiple optical fibers are contained in a tiny plastic bucket in loose tube fiber cable. The fibers are loosely positioned in a tube that is coiled in a reverse helical pattern in the cable and is actually longer than the cable’s outer sheath. Because loose tube fiber cable provides the best protection for the fiber under high tension and can be easily protected from moisture with water blocking gel or tape, it is the most…

Nowadays, PON is getting more and more popular in the access market because of its convenience. But many people may have this thought that will media converter be replaced by PON? In this article, let us talk about it. What is Media Converter? Media converter is a simple but useful devices that can provide conversion between fiber optic and other types of media. The most common use of fiber media converter is transmission between fiber and copper to extend the network or introduce fiber optic cabling to a copper based network. As these devices can be installed almost everywhere in the network and it is affordable, they are also being designated for many other applications. And there is also PoE media converter. 10/100M Ethernet Fiber Media Converter What is PoE? PoE is the abbreviation of Power over Ethernet. It is a power over Ethernet technology. This technology can transmit power through a network cable to a device that needs power at the other end. Generally, when used in this way, there are both data and power in the network cable, and there are two kinds of data at the same time, so the general cable can be reduced, which is very convenient in some cases. In addition to a suitable Ethernet cable, PoE requires a device that can be powered by PoE, as well as a dedicated PoE router or an ordinary router with an intermediary power switch. At present, the commonly used devices in this area include PoE switches and PoE media converter. They are all power supply devices. Power is supplied through them without additional power wiring. There are also PoE extenders, but they do not supply power. PoE extender is used to extend the power transmission distance. We know that the PoE power supply can reach 100 meters….

In this article, we are going to discuss the difference between CWDM and DWDM. But when we talk about CWDM and DWDM, we have to talk about WDM first. WDM stands for wavelength division multiplexing. It’s a technique for combining signals of different wavelengths for transmission through optical lines. Multiple data streams can be delivered on the same optical cable without interfering with each other since each data stream has its own wavelength. It is like increasing the number of lanes on a highway to improve the efficiency of traffic flow. WDM helps optimize network investment by maximizing the utilization of optical fiber. What is CWDM? CWDM stands for Coarse Wavelength Division Multiplexer. It can be used on a variety of fiber optic networks and is most commonly used in point-to-point topologies in enterprise and telecom access networks. Multiplexer modules for CWDM are available in four channel, eight channel, and sixteen channel variants. These modules passively multiplex optical signals from various electronic devices, route optical fibers to them, and then demultiplex the signals into individual, distinct signals for input to the device at the other end of the optical fiber link. What is DWDM? DWDM is an abbreviation for Dense Wavelength Division Multiplexer. Because DWDM uses tighter wavelength spacing to install more channels on a single fiber, the number of multiplexed channels in DWDM systems is substantially higher than in CWDM systems. Multiple DWDM channels are multiplexed onto one or two optical fibers using DWDM multiplexer/demultiplexer modules. Difference between CWDM and DWDM Channel The spacing in CWDM is greater than in DWDM. This means that CWDM can handle up to 18 channels on a single fiber pair, but DWDM can support up to 40, 80, or 96 channels. The channel spacing in DWDM is 0.8/0.4nm, while the channel spacing in CWDM…

When we talk about the methods of testing splice loss, many people would take OTDR (Optical Time Domain Reflectometer) as the best fiber optic equipment to test splice loss. But instead, OTDR is not specifically used to test splice loss. If you use OTDR to test splice loss, the measured loss value will be inaccurate. So in this article, we will talk about how to test splice loss. Why OTDR is not specifically used to test splice loss? Firstly, after a fiber is fused, if it is a long distance fiber, the splice loss will be too low for the OTDR to detect on the splice point. Secondly, even if there is a high loss point detected on the fiber, it may be caused by error operation, that is to say the fiber is not spliced correctly. After calibrating the arc, you can clean the fiber and re-splice the fiber. The right step to measure splice loss is as follow: 1. Take out a length of optical fiber. 2. Use a Light Source on one side, and an Optical Power Meter on the other side, to measure the loss of this fiber. 3. Cut the optical fiber into two pieces. 4. Use Fiber Fusion Splicer to splice the two pieces of the optical fiber. 5. After splicing, use Light Source and Optical Power Meter to measure the fiber loss again. 6. The subtraction of the two fiber loss values will be the real splice loss of the fiber. Note: You should use high precision Light Source and high precision Optical Power Meter, or the value would be inaccurate. You should keep the output power of Optical Light Source stable and in the same value. Baudcom offers all types of fiber optic test equipment and fusion splicers. For more information, please…

What is Fiber Optic Cable? Fiber optic cable is a form of network cable that has a plastic casing and includes dozens to hundreds of optical fibers. They send data messages in the form of light, which is hundreds of kilometers quicker than regular wires. Optical fiber is a technique that uses glass or plastic fiber bundles to carry information in the form of light pulses over great distances. Fiber optic cables are not damaged by the weather since they are non-metallic, and they are also safer because they do not carry current. What is A Fiber Optic Network? There are several different types of fiber optic networks. FTTX is a generalization for several configurations of fiber deployment, arranged into two groups: FTTP/FTTH/FTTB and FTTC/FTTN. FTTx stands for Fiber to the x or fiber in the loop is a generic term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications. Main Element of Fiber Optics Core Cladding Coating Cable Jacket Strengthening FIbers The Advantages of Fiber Optic Cable Bandwidth The bandwidth of fiber optics is larger. A fiber cable can readily transport more network bandwidth than a copper wire of same thickness. 10 Gbps, 40 Gbps, and 100 Gbps fiber lines are common. The capacity of single mode fiber can be up to twice that of multimode fiber. Speed Fiber optic networks are far faster than even the fastest copper Internet connections, with rates ranging from 5 Mbps to 100 Gbps. With a fast data connection over a fiber optic network, you can enjoy equal upload and download times. Transmission Distances Fiber optic cables are a low-power-loss medium, allowing for more bandwidth over longer distances while minimizing power loss. The exact distance depends on the cable type,…
