Description
AN-E3 E3 fiber converter (E3 fiber modem) can be used to provide 34.36 (E3) signal conversion between electrical interface and optical interface of E3 based network interface. It conforms to the ITU- T G.703 T3 recommendation. The converter features compactness, light weight, low power consumption and high reliability.
The 34M E3 fiber converter optical / electrical operates on 1310 nm lasers, with a typical transmission distance of 40 km over single mode optical fibers. For longer hops, 1550 nm lasers can be selected for 100 km and more distances. WDM single fiber single strand also is available on request.
Exterior power supply, all the functional blocks are integrated on a single PC board, which makes the converter compact and reliable. 220 V AC or – 48 V DC power options are available by selecting an appropriate plug-in power unit.
AN-E3 electrical interfaces are BNC sockets, “IN” is incoming E3 electrical signal and “OUT” is outgoing E3 electrical signal. The optical interfaces are SC type sockets using receive and transmit integral whole mold piece.
