A method and apparatus for controlling the power level of an optical signal includes detecting the loss of a supervisory signal counter-propagating in an optical fiber.

Method and apparatus for automatically controlling optical signal power in optical transmission systems

Embodiments of the invention generally provide a method for automatically detecting and provisioning new optical connections in a network element (NE). The detection of the optical connections is generally accomplished via optical scans, and in particular, an optical spectral analysis type scan, which may be conducted at specific times and at specific points within the NE in order to determine an association corresponding to a new connection through the NE. The automatic detecting in provisioning method of the invention may generally be implemented on connections in end terminals (ET), as well as connections in optical add/drop multiplexer (OADM) NEs. As such, embodiments of the invention allow for automatic detection and provisioning of optical circuit packs in an optical line system (OLS) based upon optical scans configured to detect the presence of valid incoming client signals through the NE.
