This module is targeted for maintaining network connectivity when power failure or system fails in an In-Line Network System. Formericas Quad Port 1.25 Gbit/s Optical Bypass Module supports Normal and Bypass modes, and can be configured to perform the Block mode. In Normal mode, two ports function independently. In Bypass mode, signal packets received from one port are loop-backed to the adjacent port. In Block mode, the module blocks the route. Formericas Quad Port 1.25 Gbit/s Optical Bypass Module can Bypass or Block its I/O ports upon a host system failure, power off, or by software request. Formericas Quad Port 1.25 Gbits Optical Bypass Module can be integrated with any brands Controllers CPU. It is suitable for connecting with in-line equipment for power failure or system maintenance. When the In-Line unit is not on or is in bypass mode, the relays within the OBM are set to bridge the optical signals directly through the optical switch, completely bypassing the In-Line equipment. Formericas OBM module provides excellent performance and reliable Optical Bypass and Block functions. All routing fibers, switches and electronics network are enclosed in a safe and compact housing which provides safe and space-saving to networking equipment. Formerica OptoElectronics Inc.
