Overview
This device has the console control,provides the 1+1 fiber path protection, point to point optical
transmission, LCD display, on the basic of our company development
of the PDH optical transmission, use the special VLSI and the SNMP
NMS.
This device is 16E1 point-to-point optical transmission equipment
with LCD display, uses the FPGA chips and easy to upgrade. It is
single board structure and its largest transmission capacity is
16E1, 4*100M channel Ethernet data and 2 AUX port which is for
transmitting other data such as RS232/RS485/RS422.
