OBP card is a kind of functional card in optical communication integrated system equipment of Glsun. Optical Bypass Protection System (OBP) is a kind of optical switch system which can bypass fault node in optical transmission network to avoid breakdown of whole network communication when there appear power interruption, hardware failure, software deadlock etc.It can automatically switch by detecting the node's optical power or signal failure. OBP is mainly used in protecting the flow control and RPT equipment.

Features

Compact size, Low insertion loss, Support hot Plug.
Wide wavelength range, Low crosstalk, Fast switching speed.
Transparent transmission, High stability, High reliability, support path latching while there is no optical signal. 
Support many kinds of signal failure bypass ways,users can control it independently or in groups.
Dual-link bypass protection, each link works independently. 
Support mirroring monitoring. 
Support the protecting ways: 1: 1 mode , 1+1 mode. 
Through NMU card , users can remotely manage the equipment.

Application

Protection for the flow control device.
Protection for signal security and analysis. 
Server failure protection in network security field.
