1. A method comprising:

  • activating, by a processing system including at least one processor, a first light source of an optical transmit/receive device of a telecommunication network, wherein the processing system includes the optical transmit/receive device, and wherein the first light source is activated by the optical transmit/receive device in response to the optical transmit/receive device being powered on;

    detecting, by the processing system, a receiving of a light from the first light source at a port of an optical add/drop multiplexer of the telecommunication network via a notification from the optical add/drop multiplexer, wherein the optical transmit/receive device comprises a transponder coupled to the port of the optical add/drop multiplexer and to a network switch;

    activating a second light source at one of;

    the optical transmit/receive device or the network switch;

    detecting a receiving of a light from the second light source at a different one of;

    the optical transmit/receive device or the network switch;

    verifying, by the processing system, the optical transmit/receive device and the port of the optical add/drop multiplexer match a network provisioning order, in response to the detecting of the receiving of the light from the first light source, wherein the verifying further comprises;

    verifying the optical transmit/receive device and the network switch match the network provisioning order, when the receiving of the light from the second light source is detected; and

    generating, by the processing system, an indication that the optical transmit/receive device is correctly installed, when both;

    the optical transmit/receive device and the port of the optical add/drop multiplexer match the network provisioning order; and

    the optical transmit/receive device and the network switch match the network provisioning order.
