16E1 fiber optical multiplexer can multiplex to 16 E1 and 8Ethernet signals for transmission over an optical fiber, resulting in reaching a longer distance without a repeaters and superior performance compared to copper media.

The 16E1 fiber optical multiplexer is the 16E1 point-to-point optical transport equipment that uses the FPGA chips and it is easy to upgrade. The outer design use the standard 19 inches rack, so the volume is little, weight is light and operation is convenient and credit.

The 16E1 fiber multiplexer can support kinds managements (SNMP,CONSOL etc.It is easy for operation and maintain.
