20km Fiber Sfp Transceiver Module 7 Dbm 2.5Gbps Sfp Module Single Mode
Gpon Ont Sfp OLT Fiber Optic Class C+ C++ C+++ Gpon-OLT-20 SFP Transceiver Module
Description
GPON OLT B+/C+ is an SFP packaged hot-swappable optical module used to connect optical data communication links (in accordance with ITU-T G.984.x). It adopts a single-fiber bidirectional design, and the uplink and downlink rates can reach up to 2.5Gbps. , Widely compatible with OLT equipment of mainstream brands in the market.
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 SFP GPON transceiver/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 wavelengths allowing bi-directional operation over a single fiber. Anything transmitted from the OLT is transmitted to all 32 lines. It is up to the customer’s system (Optical Network Unit - ONU) 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.
