PDH-4L:4E1 10/100M ethernet PDH multiplexer

4E1 10/100M ethernet PDH multiplexer

More details

4E1 10/100M ethernet PDH multiplexer:PDH-4L

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.

2.Provide 100M line Ethernet channel,support mutual negatiate, Ethernet bandwidth is set on base on multiple of 32K.;
3.Provide one RS232 channel for option;
4.Provice one hotline channel;
5.The rate of optical port is 155Mbps, transmission range can reach 25km, 40km, 60km, 80km or 120km;
6.E1 interface code is HDB3,E1 vibration characteristic conforms to ITU-T G.703、G.823 and G.742;
7.Ethernet port supports full/half duplex, 10M/100M auto-ataptable;
8.Has complete alarm function and can monitor remote device status;
9.Supports E1 loop from remote so as to detect and manage device conveniently
