BD-EOS-GE-STM1 is a dual - VCG channel Gigabit Ethernet Converter, provides 4 gigabit Ethernet interfaces (3 copper and 1 fiber Ethernet interfaces) compliant with IEEE 802.3 series standard and 2 STM-1 optical interfaces, supports 1+1 optical path protection and 2+0 mode. In 1+1 mode, the 4 Etherent interfaces share one VCG and the bandwidth is one VC4 (139Mb/s). In 2+0 mode, the 4 Ethernet interfaces share two VCG channels and the bandwidth is two VC4. Therefore, By GFP and EoS technology, BD-EOS-GE-STM1 can realize two 139Mb/s Ethernet traffic transmission over STM-1 optical line.



Compact design with 1U height, 19 inch, 155mm depth, and can be installed on standard rack
