Optical amplifiers - Test methods - Part 4-3: Power transient parameters - Single channel optical amplifiers in output power control
a) transient power response;
b) transient power overcompensation response;
c) steady-state power offset;
d) transient power response time.
The stimulus and responses behaviours under consideration include the following:
1. channel power increase (step transient);
2. channel power reduction (inverse step transient);
3. channel power increase/reduction (pulse transient);
4. channel power reduction/increase (inverse pulse transient);
5. channel power increase/reduction/increase (lightning bolt transient);
6. channel power reduction/increase/reduction (inverse lightning bolt transient).
These parameters have been included to provide a complete description of the transient behaviour of an output power transient controlled OA. The test definitions defined here are applicable if the amplifier is an OFA or an alternative OA. However, the description in Annex A concentrates on the physical performance of an OFA and provides a detailed description of the behaviour of an OFA; it does not give a similar description of other OA types. Annex B provides a detailed description background of the dynamic phenomenon in output power controlled amplifiers under transient conditions and Annex C details the impact of speed of transient inputs.This second edition cancels and replaces the first edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: alignment of the measure of amplified spontaneous emission (ASE) relative to signal power with the definition in IEC 61290-3-3.
