Description
Optical Bypass Protection System (OBP) is a kind of intelligent switching system applied in the field of optical transmission, which can automatically overpass the broken-down network nodes. It can automatically identify the status of the power supply of the network nodes and the optical signal output. When the network node is under the condition of breaking down, it can switch to bypass link to avoid the cut down of SDH network, which can make sure the whole network in a complete running status.
