Solving FTTX problem with PON technology

Classified by fiber-to-user distance, it can be divided into fiber-to-the-box (FTTCab), fiber-to-the-road (FTTC), fiber-to-the-building (FTTB), and fiber-to-the-home (FTTH) or fiber-to-the-office (FTTO). The FTTX system is mainly composed of an optical line terminal (OLT, central office equipment), an optical network unit (ONU, a customer equipment), and an optical distribution network (ODN, PLC Splitter). EPON is an IEEE standard. EPON uses a point-to-multipoint architecture and passive optical fiber transmission to provide multiple services over Ethernet. At present, IP/Ethernet applications account for more than 95% of the entire LAN communication. EPON is the most effective communication method for connecting end users of the access network by using the above-mentioned economical and efficient structure. The emergence of 10Gbps Ethernet backbone and metro ring will also make EPON the best last mile solution in the future all-optical network. GPON, FSAN and ITU have standardized it. Its technical feature is to use ITU-T-defined GFP (General framing procedure) to encapsulate and map various services such as Ethernet, TDM and ATM at the second layer, which can provide 1.25Gbps and 2.5Gbps downlink rate, and 155M, 622M, 1.25Gbps, 2.5Gbps several uplink rates, and has a strong OAM function. If you don't consider EPON, you will see that it will increase to 10Gbps (10G Ethernet is mature). Currently, GPON has advantages in high-speed and multi-service support, but the complexity and cost of technology are currently higher than EPON. Fibermall can provide users with EPON, GPON, 10G EPON, XGPON and XGSPON passive optical fiber access solutions according to different bandwidths and different service requirements of 100M, 200M, 1000M, 2.5G and 10G.
