Can different brands of OLT /ONU be compatible and interoperable?

With the rapid development of IT, there have been more and more companies geared towards this field, most popular of such companies are Huawei and ZTE to mention but a few. Not forgetting that there are lots of other IT companies with excellent products, such as Shanghai Baudcom. Is Baudcom’s ONU/ OLT compatible with Huawei and ZTE?

In this article, we will look at how compatible is different brands of OLT/ ONU can achieve compatibility and interoperability. To understand whether there can be compatible with different OLT and ONU, we first need to know what OLT and ONU are.

What is OLT?

what is OLT

The full name of OLT is Optical Line Terminal. OLT is the office equipment of telecommunications, which is used to connect optical fiber trunk lines. It acts as a switch or router in the traditional communication network, and is a device at the entrance of external network and the entrance of internal network. At the local end, the most important executive functions are traffic scheduling, buffer control, providing user-oriented passive optical network interface and bandwidth allocation.

What is ONU?

ONU is the Optical Network Unit. ONU has two functions: selectively receiving the broadcast sent by OLT, and responding to OLT if it needs to receive the data. Collect and cache the Ethernet data that the user needs to send, and send the cached data to the OLT according to the assigned sending window. The relationship between them is the relationship between the principal and the subordinate. In data transportation, it first goes through OLT and then to ONU(see figure 1). OLT is the management end, ONU is the terminal. An OLT can connect multiple ONUs.

Benefits of choosing different brands

The network equipment of many schools, enterprise buildings, etc. is hardly a single brand product, so the compatibility and interoperability between the equipment is very important. In fact, choosing different manufacturers has many advantages. First of all, the prices of products of different brands will be different, so that you can choose products with different price points according to your own needs. Secondly, the quality of products of different brands is also different. When there are more choices, you can choose the products with the best quality but the right price. Finally, the service quality of different brands is also different. It’s not that the service attitude of large enterprises is good, nor that of small enterprises is necessarily bad. As long as you choose carefully, you can definitely choose the product that suits your own mind, which actually gives people more choices.

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.
