N+1 Optical Cross Protection Equipment

N+1 Optical Cross Protection is a kind of matrix switch protection system used a backup light-emitting device to protect more than one main light-emitting device. In optical fiber transmission system, if there are 8 light-emitting devices and one of them is backup, when any of light-emitting devices breaks down but the backup works normally, the optical cross protection equipment will switch to the backup within milliseconds to keep the system working.
