IFB-244-MLC Planet Optical Fiber Bypass Switch

To protect the critical fiber optic network from power system failure, PLANET IFB-244 Series is an ultra-fast auto-recovering solution to prevent and maintain fiber network communication during power loss.
The IFB-244 Series is an industrial-grade optical fiber bypass switch with built-in 4 duplex LC or SC connectors featuring 2-channel duplex or 4-channel simplex fiber connection with optical bypass function. The optical fiber ports support 100Gbps/40Gbps/10Gbps/1Gbps/100Mbps fiber connections. It automatically switches optic network traffic to prevent link failure during power loss. It also allows the local network switch to be replaced or removed without network downtime. 

Optical Fiber Bypass Mechanism 

The IFB-244 Series applies fiber-to-fiber technology to achieve ultra-low losses and ultra-fast switching time. Two of the fiber ports are used to connect to two remote fiber switches and the other two fiber ports are used to connect to the local fiber switch. The IFB-244 Series and the local fiber Ethernet switch are powered from the same power source. 
When the system power is on, the IFB-244 Series operates in the Normal mode and forwards Ethernet packets between two remote fiber switches and the local fiber switch. 
When the system power failure occurs, the IFB-244 Series operates in the Bypass mode that directly forwards Ethernet packet between two remote fiber switches and bypass the local fiber switch. 
Once the system power is recovered, the network traffic resumes operation between two remote fiber switches and local fiber switch.

Applications

The IFB-244 Series industrial optical fiber bypass switch can be used in critical and major optical networks where fiber link failures are not tolerated, such as in power substation, train and bus station, IP surveillance system, railway monitoring, communication systems, and factory automation.
