1. A laser light supply system for fiber-optic data communication, comprising:
a laser light generator configured to generate a plurality of wavelengths of continuous wave laser light, the laser light generator being physically separate from any transmitter element configured to convert a data signal from an electrical domain to an optical domain, the laser light generator being physically separate from any receiver element configured to convert a data signal from the optical domain to the electrical domain, the laser light generator directing the plurality of wavelengths of continuous wave laser light to an optical output of the laser light generator, wherein the laser light generator is configured to maintain relative wavelength spacings between the plurality of wavelengths of continuous wave laser light generated by the laser light generator as variation in temperature of the laser light generator causes drift in the plurality of wavelengths of continuous wave laser light generated by the laser light generator;
an optical conveyance device having a first end optically connected to the optical output of the laser light generator; and
an optical distribution network having an optical input connected to a second end of the optical conveyance device, the optical distribution network configured to transmit each of the plurality of wavelengths of continuous wave laser light generated by the laser light generator to each of multiple transceivers.
