Bypass Switch is an optical path control equipment, which can automatic bypass the optical path in case the protected optical equipment is failure (such as power supply interruption, hardware failure, software deadlock etc.) for protecting network integrity.
The Bypass Switch can monitor the power supply status and optical signal status of the protected optical device in real time. When the protected optical device fails, it can removes this point of failure by automatically switching traffic via bypass mode to keep the critical network link up.

Fail-safe for network security appliance (FW,IPS,DPI,flow control devices,etc.)
