    Introduce
    PDH-4L is the 4E1 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 and 100M line Ethernet data, one channel RS232. The outer design use the standard 19 inches rack, so the volume is small, weight is light and operation is convenient and credit.

    Features
