Abstract:
A method for regulating optical power in an open loop parallel optical link upon the occurrence of an open fiber therein, said method comprising:(a) detecting an open fiber in an open loop parallel fiber optic link between a first transceiver that includes a transmitter and a receiver and a second transceiver that includes a transmitter and a receiver, wherein said fiber optic link includes N+1 channels, and wherein step (a) comprises detecting, with a means for detecting, an open fiber in the receiver of either of said first transceiver and said second transceiver; (b) disabling data transmission on all of channels 0 through N except for one designated safety channel between said first transceiver and said second transceiver, wherein step (b) comprises disabling, with a means for disabling, data transmission in at least one of said first and second transceivers; and (c) transmitting data from either of said first transceiver or said second transceiver on said safety channel at or below a threshold optical power level, wherein step (c) comprises reducing, with a means for reducing, optical power in the transmitters of said first and second transceivers.
