Abstract: Devices, computer-readable media and methods are disclosed for verifying that an optical transmit/receive device is correctly installed. For example, a processing system including at least one processor may activate a first light source of an optical transmit/receive device of a telecommunication network and detect a receiving of a light from the first light source at a port of an optical add/drop multiplexer of the telecommunication network. The processing system may then verify the optical transmit/receive device and the port of the optical add/drop multiplexer match a network provisioning order, when the receiving of the light from the first light source is detected, and may generate an indication that the optical transmit/receive device is correctly installed, when the optical transmit/receive device and the port of the optical add/drop multiplexer match the network provisioning order.

Abstract: Devices, computer-readable media and methods are disclosed for determining reachability for a wavelength connection in a telecommunication network. For example, a processor deployed in a telecommunication network may calculate a fiber loss on a link in the telecommunication network using optical power measurements and determine that a destination node of a wavelength connection is not reachable via a path that includes the link based upon the fiber loss of the link that is calculated. In one example, the determining is based upon a number of links in the path, an effective fiber loss for each link in the path, a penalty for nodes in the path, and an acceptable loss value. The processor may further perform a remedial action in response to determining that the destination node of the wavelength connection is not reachable via the path.

Abstract: An amplifier receives an optical signal including a number of labeled channels via a fiber. The amplifier determines a count of the labeled channels and a spectral distribution of the labeled channels. The amplifier adjusts a parameter of the amplifier based on the count of the labeled channels and the spectral distribution of the labeled channels. The amplifier amplifies the optical signal at an adjusted output gain resulting from adjusting the parameter of the amplifier.
