OPTILINK OP-GPON OLT 9008A complies with ITU-T G.984/G.988 and meets requirements about GPON OLT in Network Access Technical Requirements. It supports the Asymmetric uplink 1.25Gbps/downlink 2.5Gbps PON transmission rate, efficient bandwidth usage and Ethernet services, helping carriers to provide reliable services to their users. Its coupling ratio ups to 1:128, and its support of different hybrid ONU networks minimize the carrier’s investment. It is based on the edge-cutting technologies, is strong in functions. A few of its functions such as QoS guarantee, SLA and DBA can be easily listed out.
