Method and system for making optical network terminal support multi protocol

Abstract

The invention relates to a method for making optical network terminal support multi protocols, and relative system. Wherein, said method comprises: the optical network terminal processes protocol reorganization on received data signal; according to recognized protocol type, processing relative protocol selection and distribution on the optical network terminal, to make it able to receive the data signals with different protocol types. Said system comprises: a protocol recognize module, a protocol setting module, a data processing module, and a data sending module. The invention can simplify the structure of optical network terminal and reduce the terminal number.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and a system for enabling an optical network terminal to support multiple protocols. Background technique [0002] Passive Optical Network (PON) technology is a point-to-multipoint optical fiber transmission and access technology. The downlink adopts broadcast mode and the uplink adopts time division multiple access mode. It can flexibly form tree, star, bus and other topological structures. , No node equipment is required at the optical branch point, only a simple passive optical splitter needs to be installed, the optical signal is no longer amplified and regenerated during transmission, and the splitting of the network is realized by the optical splitter. [0003] The current passive optical network (PON) technologies mainly include broadband passive optical network (BPON), Ethernet passive optical network (EPON), gigabit transmission passive optical net...

AI Technical Summary

Problems solved by technology

[0009] The current implementation scheme is that each PON technology owns and uses its own OLT, ONU, and ONT, and devices belonging to different PON technologies are independent of each other and cannot be compatible with each other.

Each type of PON must use an ONT that can identify its own network protocol, resulting in the need to design and manufacture different devices for different networks. It is impossible to use the same device to receive signals from different types of networks, resulting in low resource utilization and complicated device management.
