Abstract :
In a wavelength division multiple access passive optical network based on spectral slicing, the wavelength drift of a multiplexer/demultiplexer due to varying ambient temperature in the passive outside plant is compensated by controlling the temperature of the other device at central office location to wavelength alignment.
