ABSTRACT:
Protection is provided by switching an optical transmission signal. An optical transmission system operating in a ring configuration, comprises optical transmitters and optical receivers connected in such a way as to provide working and protection on paths. When a failure occurs that disrupts the signal between two telecommunication nodal sites, optical switches are used to switch the signals from a working path to a protection path away from the disruption.
