VFL is now one of the most commonly used fiber optic testing devices to trace optical fibers, check fiber continuity and find faults such as breaks, bad splices and tight, sharp bends in fiber optic cable. Visual Fault Locator What is VFL? VFL, also called Visual Fault Locator, is a device which...

When looking for the right cables for electrical distribution, there are many different options that you can play around with. One of them is the All Dielectric Self Supporting (ADSS) cable. This is a type of self-supporting optical fiber cable that does not require any kind of support in distrib...

Fiber optic technology is getting more and more popular nowadays in the professional networking world. Copper cable or fiber optics? This is one of the most common questions asked by business owners as these are the most popular choices in the IT industry. A good internet connection is essential ...

Since this ADSS fiber doesn’t need any running wire to support it, it has been widely used in outdoor environment. It is used by electrical utility companies as a communications medium, installed along existing overhead transmission lines.     What Is ADSS Cable? ADSS cable is a type o...

What Is OTDR? OTDR stands for an optical time-domain reflectometer. It is an instrument used to test an optical fiber. This equipment works by injecting a series of optical pulses into the fiber and extracts, from the same end, the light that is scattered (Rayleigh backscatter) or reflected back ...

What is a Fiber Optical Transceiver? A fiber optical transceiver is a device that encodes and decodes data into light pulses for transfer via a fiber cable. It achieves this by simply having a transmitter on one end and a receiver on the other end, hence called a transceiver (a combination of tra...

The acronyms SC, LC, FC and ST refer to the most common types of optical connectors in FTTH applications and data networks. As for the PC/UPC/APC terminology, it refers to the type of polishing applied to the optical terminal (ferrule) which makes possible laser light pulses to cross through two ...

Optical fiber has brought changes to the telecommunication industry throughout the world; therefore, it is essential for us to learn some skills necessary for working with optical fiber. It is known to all that when adopting or splicing a fiber, clean ends should be assured. And fiber optic cleav...

Fiber optic splitters play an increasingly significant role in many of today’s optical network topologies. They provide capabilities that help users maximize the functionality of optical network circuits from FTTx systems to traditional optical networks. And usually they are placed in the central...

A patch cord is a length of cable with connectors on each end that is used to connect end devices to power sources. These cables are mainly used to connect one electronic device to another. They are typically copper cables that have RJ45, TERA or GG45 connectors on both ends. A patch cord may als...

Fiber splicing is also called fiber optic cable splicing, that is using a special equipment optical fiber fusion splicer to fuse two bare fibers that are not connected into a whole. Fiber splicing is not as simple as fusing two bare fibers together, it’s a process: stripping fiber cable jacket an...

Lose the four screws a bit but do not remove them. Then move the whole electrodes base to the left/right a bit (if arcing is in the left, then move electrode base in the right position and test below procedures) After setting the electrodes, press the ARC button (Every time you do the arcing, pl...

Sorting through cables and connectivity options can be a frustrating exercise. That’s what this article is designed to help out with — how to select the right type of fiber optic cable.   Simplex vs. Duplex Simplex vs. duplex is just the difference between one fiber or two; between on...

What does a Fusion Splicer do? A Fusion Splicer is used for combining or splicing two optical fibers end to end via fusion. The objective here is to fuse the fibers together in such a way that no light is reflected or refracted and having the spliced fiber is as strong as the regular fibers. &nb...

There are several key elements that must be followed in the FTTH project. The correct implementation of these key elements can greatly reduce the investment of the project, increase the speed of construction, and reserve enough space for upgrading or expansion, effectively extending the sustainab...

The optical fiber fusion splicer is the most widely used splicing method in optical fiber engineering. Its principle is to use the arc fusion splicing method to generate a high temperature above 2000 ℃ by arc discharge to fuse two optical fibers into one optical fiber. A high-performance optical ...

With the development of the network, optical fiber is used as a medium for data transmission in the integrated wiring system. Because of its high transmission rate and long distance, it is more and more widely used. The optical fiber is non-conductive and can be protected from inrush current. The...

At present, 10G optical modules, 40G optical modules, and 100G optical modules are showing a rapid growth trend in the market. The global revenue of 10G optical modules, 40G optical modules, and 100G optical modules will account for more than half of the overall optical module market. But, what a...

What is Optical Fiber Attenuation？ Optical fiber attenuation refers to the attenuation per unit length of the optical fiber, in dB/km. The level of fiber attenuation directly affects the transmission distance or the distance between relay stations. What is the maximum value of Optical Fiber Atte...

Gigabit Ethernet switches generally have two ports: RJ45 port and SFP port. Both of these ports can be used for Gigabit Ethernet transmission. Then, what is the difference between RJ45 port and SFP port. And how to choose? With the development of science and technology, people’s demand for networ...
