Abstract
A system and method for connecting traffic along a communications network is accomplished by rerouting traffic upon the detection of a fault condition along a primary connection path. A laser-diode transmitter, uniquely tagged, transmits a specific bit pattern signature header unique to the transmitter at the beginning of a predetermined transmission sequence. The network recognizes the unique identifier and configures the network to route all traffic from the identified transmitter along a specific path to its intended destination.
