METHOD AND SYSTEM FOR OPTICAL CONNECTION VALIDATION
First Claim
1. A method of connecting a transceiver including a transmitter and a receiver to an optical add/drop multiplexer (OADM), the method comprising:
- providing a loopback connection between an Add path and a Drop path of the OADM, the loopback connection coupling a selected loopback channel wavelength from the Add path to the Drop path;
connecting the transmitter to an Add port of the OADM;
connecting the receiver to a Drop port of the OADM;
controlling the OADM to switch the selected loopback channel wavelength in the Drop path to at least one intended drop port to which the receiver should be connected;
controlling the transmitter to transmit a predetermined test signal using the loopback channel wavelength; and
detecting the test signal by the receiver to verify that the receiver is connected to the at least one intended drop port.

Abstract
An optical add/drop multiplexer (OADM) having an Add path for adding optical channel signals input through a plurality of Add ports to an outbound dense wavelength division multiplexed (DWDM) signal, and a Drop path for switching selected channels from an inbound DWDM signal to one or more of a plurality of Drop ports. The OADM has a loopback connection between the Add path and the Drop path. The loopback connection couples a selected loopback channel wavelength from the Add path to the Drop path. The physical connection between a transceiver and the OADM can be verified by connecting the transmitter to an Add port of the OADM and the receiver to a Drop port of the OADM. The OADM is controlled to switch the selected loopback channel wavelength in the Drop path to at least one intended drop port to which the receiver should be connected, and the transmitter is controlled to transmit a predetermined test signal using the loopback channel wavelength. Detecting the test signal by the receiver verifies that the receiver is connected to the at least one intended drop port.
