Abstract:
1. A method of operating a production optical amplifier comprising: (i) determining a data set of training amplified spontaneous emission (ASE) values of a training optical amplifier over a plurality of training operating conditions, (ii) determining a data set of production ASE values of the production optical amplifier over a plurality of production operating conditions, the plurality of production operating conditions corresponding to at least a sub-set of the plurality of training operating conditions, (iii) determining an adjusted data set of adjusted ASE values produced by extrapolation from the production data set so that the adjusted data set is provided over a plurality of operating conditions corresponding to at least the plurality of training operating conditions, (iv) determining, for each of a plurality of operating conditions, a dynamic ASE tilt factor from the training data set and the adjusted data set so determined, (v) determining a larger data set of ASE values over a wider set of operating conditions than either the training data set or the production data set from the adjusted ASE data set and the dynamic ASE tilt factor, and (vi) compensating the optical output power of the production optical amplifier in correspondence with the larger ASE data set generated from the production data set and the dynamic ASE tilt factor over the plurality of operating conditions, which is a larger set of operating conditions than that of the training data set or production data set.
