OVERVIEW: 

BD-OP-8E1-4GE is the 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 8E1 and 4*10/100*1000M Ethernet data.The outer design use the standard 19 inches rack, so the volume is small, weight is light and operation is convenient and credit.

Feature:

•  Provides 8 E1 transparent transmission ;

•  Provide 1~4 channel 10/100*1000M Ethernet ,4 Ethernet support VLAN isolation for option




• The rate of optical port is 1.25G, transmission

• E1 interface code is HDB3,E1 vibration characteristic conforms to ITU-T G.703,G.823 and G.742;




•  Ethernet port supports full/half duplex, 10M/100/1000M auto-ataptable;

• Has complete alarm function for device status;

• Supports E1 loop from remote so as to detect and manage device conveniently;
  

• he combination AC220V and DC-48V for redundant for option
