General
GPON OLT SFPis designed for OLT side in GPON network. OLT is a equipment integrating L2/L3 switch function, which is located in central office (CO). The main function is to control the information float in both directions: upstream and downstream.
The GPON OLT plays an inevitable role in the upstream and downstream transmission. In order to put across the transmission process, the downstream transmission is taken as an example. A single mode optical fiber coming from OLT (at the central office) PON port, runs to the passive optical splitter(POS) located near end users. And then the optical splitter will divide signals into separate paths which can provide service up to 64 end users.
In this basic GPON topology, a GPON OLT is used to connect a single-mode fiber patch cable to a passive optical splitter. Therefore, GPON OLT transceiver works to get the data, and video traffic from metro network or from a long-haul network.
