The 4E1 fiber multiplexer is part of Multi E1 and Fast Ethernet transmission system family, used to build a 150Mb/s optical point-to-point link. Based on an ASIC chip; it performs the transportation of 4 E1 and a fast Ethernet at full speed. The 4E1 fiber multiplexer (BD-OP-4E1-4ETH/M) also provides an order-wire and an auxiliary UART interface for Management. The OPTIMUX offers a highly integrated solution for the perfect function, stable performance and convenience with low power consumption.

The fiber optical multiplexer can support GUI management, which monitor the device’s operation status. The user also can configure the device easily.
