GPON, FSAN and ITU have standardized it. Its technical feature is to use ITU-T defined GFP(Universal Frame Protocol) to package and map Ethernet, TDM, ATM and other services on the second floor. Can provide 1.25 Gbps and 2.5 Gbps downlink rate, and 155M, 622M, 1.25 Gbps, 2.5 Gbps uplink rate, and has a strong OAM function. If you do not consider that EPON can be seen soon, it will increase to 10 Gbps rate(10G Ethernet is mature). At present, GPON has an advantage in terms of high speed and support for multiple services, but the complexity and cost of the technology are currently higher than EPON.
PON system is undoubtedly one of the best, EPON and GPON, the two technologies are different, whether EPON technology or GPON technology, its application is largely determined by the rapid reduction of optical fiber access costs and business requirements, and the price is the most core factor.
