Patent ID: 8509621

Claim:
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 drop port to which the receiver is connected corresponds with the at least one intended drop port.
