(PDH(4ETH+8E1

General information
4/8E1+4ETH Fiber Optical Multiplexer is the 4/8E1 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 4/8E1 and 4*100M line Ethernet data. the Ethernet bandwidth is set on base on multiple of 32K.The outer design use the standard 19 inches rack, so the volume is small, weight is light and operation is convenient and credit.
