Abstract
A local node of an optical network obtains local operating parameters associated with a bi-directional link to a remote node of the optical network, including a nominal local wavelength and a local temperature. The local node also obtains remote operating parameters of the remote node, including a nominal remote wavelength and a remote temperature. The local node further determines a target local wavelength based on a comparison of the local operating parameters and the remote operating parameters, and tunes a local transmitter to generate light at the target local wavelength. The local node also tunes a local filter to transmit light at the target local wavelength and reflect light at a target remote wavelength. This may be done by exchanging a configuration identifier with the remote node. The configuration identifier from the remote node is encoded in pulses of light from a remote transmitter in the remote node.
