Effective network detour to bypass single-point or multi-point power failures
Redundancy technologies are great for network topologies. As one node fails, the system quickly finds another path and continues to run again. However, if two or more nodes fail in a ring structure, or if just one node fails in a daisy chain structure, the network would be irrecoverable until the node problems are solved.
Let ORing introduce the natural yet critically important network redundancy – Hardware Bypass, which effectively avoids single-point power failure in daisy chain topology or multi-point power failures in ring topology. For conventional wired Ethernet network, there is the Cooper Interface Bypass. An ORing Ethernet switch with Cooper Interface Bypass would have 2 of the Ethernet ports designated as the bypass path. Under normal circumstances, these ports would function just like any other port. However, when power failure occurs, the internal bypass circuit connects these 2 ports together, effectively letting the network ride through this Ethernet switch that has lost power to operate. An example of an ORing switch with Cooper Interface Bypass is TES-3080-M12-BP2.
ORing also has the optical solution for hardware bypass network redundancy – Optical Interface Bypass in a dedicated optical bypass switch such as one from the IBS-102FX series. In normal operations, the Bypass switch diverts data from the Network ports to the Monitor ports. When power failure occurs, the Network data traffic is routed directly to the other Network port, and the Monitor data traffic is routed directly to the other Monitor port. Moreover, the Bypass switch has relay output for power failure warning. For different optical data transmission modes, IBS-102FX series comes in two variations – IBS-102FX-MM-LC for multi-mode optical links and IBS-102FX-SS-LC for single-mode optical links.
