Abstract:
1. A compensation process for a network comprising: evaluating variations in amplifier gain over a selected range of wavelengths; establishing an inverse function of the gain variations; predetermining an output parameter of an optical transmitter in accordance with a corresponding value of the inverse function on a per wavelength basis including predetermining an output parameter for each one of a plurality of optical transmitters in accordance with a corresponding value of the inverse function selected from a plurality of corresponding wavelengths; providing a plurality of lasers as optical transmitters; setting a power output parameter for each member of the plurality of lasers in accordance with a corresponding value of the inverse function wherein the laser modules each have substantially the same power output profile and which includes providing pre-set laser modules for installation in a network where the number of optical spans between a module and a respective receiver is not larger than a predetermined exponent.
