Dynamic wavelength management using bi-directional communication for the prevention of optical beat interference

A method for adjusting an optical transmitter wavelength of each of a plurality of customer premises equipment, wherein each of the plurality of customer premises equipment is in bidirectional communication with a customer premises equipment controller, and wherein a cluster of customer premises equipment that use a thermo-electric cooler to control wavelength, are instructed by the customer premises equipment controller to change their wavelengths as a group in concert with the changes in temperature to extend an operating temperature range of the cluster of customer premises equipment and to reduce power consumption of the thermo-electric cooler.

A customer premises apparatus for optical communications comprising:

• an optical diplexer, a photodiode coupled to the optical diplexer, an RF amplifier coupled to the photodiode, an RF demodulator coupled to the RF amplifier, a microcontroller coupled to the RF demodulator, a memory coupled to the microcontroller, an RF modulator coupled to the microcontroller, and a laser coupled between the RF modulator and the optical diplexer, wherein the laser has an adjustable optical wavelength, and wherein the microcontroller is capable of dynamically managing the adjustable optical wavelength.
