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

FMO is the E1point-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 16E1. The outer design use the standard 19 inches rack, so the volume is little, weight is light and operation is convenient and credit.

The FMO E1fiber 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 the 4~16E1 fiber Multiplexer, it is stable and easy to maintenance, install and small in size. It has one digital service telephone.
