Product Description:
4E1/8E1/16E1 fiber optical multiplexer 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.
4E1/8E1/6E1 fiber optical 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, it is stable and easy to maintenance, install and small in size. It has one digital service telephone.
