The Waste of Optical Transmission Bandwidth

June 09, 2021

On the other hand, more than 95% of users use Ethernet to connect to their internal networks, and the current access network forces users to purchase expensive routers to connect to the telecommunications access network. The conversion of the protocol also brings a lot of additional overhead. Operators choose ATM and SDH / SONET to transmit IP services mainly considering network scalability, reliability and technology maturity. Although these methods have many advantages, they have obvious shortcomings in the management of the bandwidth that maps layer 2 data to layer 1. From the perspective of transmission, they need to determine the bandwidth required for transmission based on the "dedicated line" method. The data entering the backbone network follows the rules of the traditional TDM network. Even higher. These methods result in a waste of optical transmission bandwidth.

There are many GPON Devices under GL-COM. GPON ONT also known as GPON ONU series products include GPON VOIP ONT, GPON CATV ONT, GPON 4GE ONT, GPON 1GE ONT, etc.
