Gigabit Passive Optical Networks (E/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(Gpon) & 1.25Gbps (Epon).
In today’s world, hot-swappable transceivers are hard to find. It is hard to trust the brand offering this product but you don’t have to worry about it anymore because the EPON SFP is one of the best in the market. This device when installed in the office will improve the working scenario because when you have to swap it, you neither have to disrupt the running devices in the workplace nor you will have to reboot any of them. You can simply plug and play with the latest EPON SFP.
