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.

First claim

What is claimed is:

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 including the optical transmit/receive device, 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;
routing, by the processing system including the optical transmit/receive device, a light from a second light source of the telecommunication network to the port of the optical add/drop multiplexer;
detecting, by the processing system including the optical transmit/receive device, a receiving of the light from the second light source at the optical transmit/receive device;
verifying, by the processing system including the optical transmit/receive device, that the optical transmit/receive device and the port of the optical add/drop multiplexer match a network provisioning order, wherein the verifying comprises determining that the light from the first light source was received at the port of the optical add/drop multiplexer and determining that the light from the second light source was received at the optical transmit/receive device; and
generating, by the processing system including the optical transmit/receive device, 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.

2. The method of claim 1 , wherein the optical transmit/receive device comprises a transceiver integrated into a network switch.

3. The method of claim 1 , wherein the indication comprises at least one of:
a visual indication via the optical transmit/receive device or an audio indication via the optical transmit/receive device.

4. The method of claim 1 , wherein the indication comprises at least one of:
a visual indication via the optical add/drop multiplexer or an audio indication via the optical add/drop multiplexer.

5. The method of claim 1 , wherein the indication comprises at least one of:
a visual indication via a network switch associated with the optical transmit/receive device or an audio indication via the network switch associated with the optical transmit/receive device.

6. The method of claim 1 , wherein the indication comprises at least one of:
a visual indication via a device of a network technician or an audio indication via the device of the network technician.

7. The method of claim 1 , wherein the indication comprises an entry in a network provisioning system.

8. A non-transitory computer-readable medium storing instructions which, when executed by a processing system including at least one processor, cause the processing system to perform operations, the operations comprising:
activating a first light source of an optical transponder of a telecommunication network, wherein the processing system includes the optical transponder, and wherein the first light source is activated by the processing system including the optical transponder in response to the optical transponder being powered on;
detecting a receiving of a light from the first light source at a network switch of the telecommunication network, wherein the detecting is performed by the processing system including the optical transponder in response to receiving a notification from the network switch;
activating a second light source at the network switch;
detecting a receiving of a light from the second light source at the optical transponder;
verifying that the optical transponder and the network switch match a network provisioning order, wherein the verifying is performed by the processing system including the optical transponder, and wherein the verifying comprises determining that the light from the first light source was received at the network switch and determining that the light from the second light source was received at the optical transponder; and
generating an indication that the optical transponder is correctly installed, wherein the generating is performed by the processing system including the optical transponder in response to the optical transponder and the network switch matching the network provisioning order.

9. The non-transitory computer-readable medium of claim 8 , wherein the indication comprises at least one of:
an entry in a network provisioning system;
a visual indication via the optical transponder; or
an audio indication via the optical transponder.

10. The non-transitory computer-readable medium of claim 8 , wherein the indication comprises at least one of:
an entry in a network provisioning system;
a visual indication via the network switch; or
an audio indication via the network switch.

11. The non-transitory computer-readable medium of claim 8 , wherein the indication comprises at least one of:
an entry in a network provisioning system;
a visual indication via an optical add/drop multiplexer associated with the optical transponder; or
an audio indication via the optical add/drop multiplexer associated with the optical transponder.

12. The non-transitory computer-readable medium of claim 8 , wherein the indication comprises at least one of:
an entry in a network provisioning system;
a visual indication via a device of a network technician; or
an audio indication via the device of the network technician.

13. A method comprising: activating, by a processing system including at least one processor, a first light source of an optical transponder of a telecommunication network, wherein the processing system includes the optical transponder, and wherein the first light source is activated by the optical transponder in response to the optical transponder being powered on;
detecting, by the processing system including the optical transponder, a receiving of a light from the first light source at a network switch of the telecommunication network via a notification from the network switch;
activating, by the processing system including the optical transponder, a second light source at the network switch;
detecting, by the processing system including the optical transponder, a receiving of a light from the second light source at the optical transponder;
verifying, by the processing system including the optical transponder, that the optical transponder and the network switch match a network provisioning order, wherein the verifying comprises determining that the light from the first light source was received at the network switch and determining that the light from the second light source was received by the optical transponder; and
