Single E1 optical transmission equipment can be used as the local network relay transmission device, especially for a mobile communication network base station transmission optical terminal equipment and rental equipment. The devices are small, light weight and compact structure, convenient installation and maintenance; transmission quality, reliable operation.The product is an electrical interface with the PBX E1 or E1 router connected to the device, optical interface for multimode and singlemode work environment. MODEM V.35 fiber can be used in pairs, can also be achieved (Ethernet Bridge) ----- (E1 Optical Modem) ----- (Ethernet Optical Modem) network structure. Apply different fiber link transmission band management channel, you can transfer data from the same fiber-optic lines for local and remote equipment monitoring and control, and interfere with each other; provide SNMP network management.
