Gepon Solution Application

Gepon system consists of Gepon OLT, Gepon ONU and Optical Fiber Splitters. Gepon OLT is the master device (also sorted as Layer 2 Access Switching equipment) that connects to Gepon ONU with Optical Fiber Splitters. Gepon ONU is the subscriber device that is set at the Subscribers’house. With the NMS installed in the Server PC at Gepon OLT side, administrators can manage/configure the Gepon ONU in the Gepon OLT’s server room remotely. With all 1 gigabit or 10Gigabit fiber connected, Gepon system offers a large bandwidth that can meet or exceed the transmission requirements for IPTV, VoIP and Data services.

It is a great option for Fiber To The Home, Fiber To The Building, etc solutions.
