Sopto EPON SFP module is a series of optical transceiver modules operating in Ethernet Passive Optical Networks (EPON).
From the Central Office’s (CO) Optical Line Terminal (OLT, with EPON SFP transceiver/module) a single strand of fiber goes out to a passive optical splitter where its signal is multiplied to maximum 64 different lines in EPON. The Transmit and Receive signals operate on different wavelengths realizing bi-directional operation at 1490nm/1310nm wavelengths over a single fiber.
Ethernet Passive Optical Networks (GEPON or EPON) IEEE 802.3ah standards have defined downstream data rates up to 1.25Gbps.
