Tansmission of 4 E1 /8E1/16E1 signal through fiber, this series device provide two fiber for redundant.

4E1/8E1/16E1 is a family of FMO, this model it can multiplex to 4E1/8E1/16E1 signals for transmission over an optical fiber, resulting in reaching a longer distance without a repeaters and superior performance compared to copper media.

4E1/8E1/16E1 is the 4E1/8E1/16E1 point-to-point optical transport equipment that uses the FPGA chips and it is easy to upgrade. It is single board structure and the largest transmission capacity is 4E1/8E1/16E1. The outer design use the standard 19 inches rack, so the volume is little, weight is light and operation is convenient and credit.

4E1/8E1/16E1 fiber Multiplexer , is use the PDH fiber transmission technologies. The 2M (E1) interfaces can connect with the exchanger, light loop device and multi-diplexer directly to form the mircomidi or the special network. Complete alarm function for 4E1/8E1/16E1 fiber Multiplexer, it is stable and easy to maintenance, install and small in size. It has one digital service telephone.
