Compatibility of Different Brands OLT and ONU

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 manufacturers. You can approach the manufacturer’s engineer to solve any problems. Because there are many ONUs of different brands on the market, we take Baudcom’s ONUs as an example. Although OLTs like Huawei, ZTE, Fiberhome and other brands have limitations, Baudcom has strong technical support to help customers solve compatibility problems. Baudcom engineers can help customers improve the operating environment and improve the compatibility of OLT. then Huawei OLT can work with Baudcom ONU, so as other brands of OLT. Also Baudcom’s OLT is compatible with nearly all brands ONU, including Huawei, ZTE, Fiberhome, etc.

To know whether your OLT and ONU are compatible, you may also need to know what OLT and ONU are and how they are used.

What is OLT?

In passive optical networks, OLTs, also known as Optical Line Terminals, serve as endpoint hardware devices. The main role of the OLT is to convert electrical signals used by service provider equipment to optical fiber signals used by passive optical networks (PON) and to coordinate multiplexing between end user equipment (ONU or ONT). In a typical communication network, it serves as a switch or router. It is both the external network’s and the internal network’s entry point.

OLT Functions

Traffic scheduling, user-oriented passive optical network interface, buffer control, and bandwidth allocation are the most significant features of the OLT. In a summary, the OLT provides the following functions: In the upstream channel, the OLT connects to the PON network and translates the fiber service (FiOS) standard signals into the PON system’s frequencies and frames. In the downstream channel, the OLT sends collected data over the ODN network and distributes it to all ONU user terminal devices, as well as coordinating numerous analog or digital signals created by ONT conversion devices into a single signal.

What is ONU?

ONU stands for Optical Network Unit, and it is split into two types, active optical network units and passive optical network units. In an optical access network, an ONU is a device that provides users with a number of service interfaces. The ONU’s network interface is an optical interface. It’s the electrical interface on the user’s end. An optical node is a device that has an uplink optical transmitter, an optical receiver, and a multi-bridge amplifier network monitoring device. Between the OLT and the ONU, optical fibers and splitters are used to distribute the optical fiber network. The OLT is connected to the ONU by a single fiber, and the OLT is connected to the ONU via the PON. The ONU supports the “triple play” concept by providing telephony services, data, and IPTV.

ONU Functions

Data, IPTV, VOIP, and other services are all available through ONU’s Triple Play Service. The broadcast data transmitted by the OLT is received by the ONU. The ONU gathers and holds the Ethernet data that the user wants to transmit, then sends it to the OLT according to the sending window that the user has been assigned. OAM supports ONU’s extensive remote management features.

Testimonials

Lomoveishiy – Finland

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Raymond – USA

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
