To protect the critical fiber optical 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 Norman 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 to the IFB-244 Series and the local fiber switch, the network traffic is resuming forward between two remote fiber switches and local fiber switch.
| Operation Mode | Power Source | Optical Traffic Route |
| Normal Mode | Power on | IFB-244 forwards packets between two remote network switches and the local switch |
| Bypass Mode | Power loss | IFB 244 directly forwards packets between two remote network switches and bypass the local switch |
Environmentally Hardened Design
The IFB-244 Series possesses an integrated power supply source with a wide range of voltages (9 to 48V DC or 24V AC) for worldwide high availability applications requiring dual or backup power inputs. Being able to operate under wide temperature range from -40 to 75 degrees C, the IFB-244 Series can be placed in almost any difficult environment.
Robust Protection
The IFB-244 Series provides contact discharge of ±6KV DC and air discharge of ±8KV DC for Ethernet ESD protection. It also supports ±6KV surge immunity to improve product stability and protects users’ networks from devastating ESD attacks, making sure the flow of operation does not fluctuate.
Flexible and Easy Installation with Limited Space
The IFB-244 Series is specially designed to be installed in a narrow environment, such as wall enclosure. It can be installed by fixed wall mounting or DIN rail, thereby making its usability more flexibly and easily in any space-limited location.
Dual Power Input for High Availability Network System
The IFB-244 Series features a strong dual power input system with wide-ranging voltages incorporated into customer’s automation network to enhance system reliability and uptime. In the example below, when power supply 1 fails to work, the hardware failover function will be activated automatically to keep powering the IFB-244 Series via power supply 2 without any break of operation.
