Abstract
The in-fiber safety interlock system includes a high power (Class IV) laser interlocked to an OTDR. A plurality of WDM data signals are transmitted over the fiber system, including a terminal portion and an extended portion. A control circuit is connected to the laser and the OTDR. The OTDR monitors the integrity of the fiber system, including both the terminal portion and the extended portion. If the OTDR detects a fault in the optical transmission path, the OTDR and the control circuit operate to automatically disable or shut down the laser.
