Comnet CN-OBSM, CN-OBSS Specsheet
Industrial 2-Port Optical Bypass Switch
with 4 × LC Duplex Connectors
CN-OB(M,S)
DIN RAILREDUNDANT
The ComNet CN-OB(M,S) external bypass switches for 100M/1G/10G fiber optic
networks protect the network from failures and ensure network integrity during power
loss. Each of these fiber optical bypass switches includes Network ports and Monitor
ports. The Network ports are used for connection to main-network connections and
provide protection mechanism, and the Monitor ports are used for down-link local
networking device. When the power is on, the operation mode of the Bypass switch is
set to Normal, and the local networking device is connected with main-network. When
power failure occurs, the Bypass switch is swiftly set to bypass mode to isolate the mainnetwork from the local networking device.
