What are the parts of the network with OLT?

Can be divided into three parts
Core part: including aggregation and distribution, business processing and ODN adaptation functions
Service part: Provide service interface functions, including interface adaptation, interface protection, etc., as well as signaling processing and media transmission format conversion functions for specific services when needed
Public part: including power supply and OAM functions

OLT Device is one of the most commonly used fiber optic equipment, which is also known as network device and FTTB FTTX equipment. Among these, one of the most commonly seen is EPON OLT. EPON OLT usually have uplink port and downlink port which supports data transfer, which is very important to WEB management function of OLT.

Product Description
