Sopto GPON SFP module is a series of optical transceiver modules operating in Gigabit Passive Optical Networks (GPON).
From the Central Office’s (CO) Optical Line Terminal (OLT, with GPON SFP transceiver/module) a single strand of fiber goes out to a passive optical splitter where its signal is multiplied to maximum 128 different lines in GPON. The Transmit and Receive signals operate on different wavelengths realizing bi-directional operation at 1490nm/1310nm wavelengths over a single fiber. Gigabit Passive Optical Networks (GPON) ITU G.984 standards have defined downstream data rates up to 2.5Gbps.
Features of GPON SFP Module
