Optical Line Termination

Optical line terminal (OLT) is one of the key components used in GEPON networks, the optical line termination is usually put in the central control room. Our typical optical line terminal adopts 19 inch size rack design, it is with 3U height and 16 slots, every 2 of them is offered to one OLT module, supporting 8 OLT module max and 256 remote ONU equipment. This system make it a stable big bandwidth data transmission over 10 to 20km distance. It is able to supply transmit function at L2/L3 wire speed. Each PON line provides a direct optical interface to the core Ethernet/IP network/CATV, provide uplink port, downlink port and management port, which supports 1Gbps upstream and downstream symmetrical bandwidth, It is also compliant to the IEEE802.3ah standard.

The optical line terminal features high QOS and flexible dynamic bandwidth allocation, it can implement any change from 1M to 1G access bandwidth. This optical line terminal supports auto-discovery and auto-register, user line testing, remote ONU fiber failure and power failure alert. It also contains abundant operation and manageable features such as MAC address limited and leached, IP address limited and leached, bandwidth control, VLAN and flow control. The optical line terminal also features the network management function.
