The GPON Series Optical Modules are designed for Gigabit Passive Optical Network (GPON) applications, providing stable, high-speed optical communication between Optical Line Terminals (OLT) and Optical Network Units (ONU/ONT).
Gigabit Passive Optical Networks(GPON)is the leading technology being used in FTTx(FTTH) deployments.PON is different than other optical network topologies in that it is a Point to Multi-Point(P2MP)topology From the Central Office’s(- CO)Optical Line Terminal(OLT with SFPGPON Transcever/module)a single strand of fiber goes out to a passive optical splitter where its signal is multiplied to 64(128 different lines.
The Transmit and Receive signals operate on different wave- lengths allowingbi-directional operation over a single fiber. Anything transmitted from the OLT is transmitted to all 32 lines.
lt is up to the customer’ s system(Optical Network Unit-GMK)to determine what packets are for that customer.All other packets are discarded.The PoN current standards have defined downstream data rates up to 2.5Gbps.
