Abstract
An optical node comprises a tunable optical transceiver having a laser and a temperature element. The optical node also comprises a wavelength shift stabilization circuit configured to adjust current provided to the temperature element such that wavelength shifts, due to changes in a drive current applied to the tunable optical transceiver, are reduced.
