Optical amplifiers - Test methods Part 4-3: Power transient parameters - Single channel optical amplifiers in output power control
 N EN 61290-4-3

Annotation

This part of IEC 61290 applies to output power controlled optically amplified, elementary subsystems. It applies to optical fibre amplifiers (OFA) using active fibres containing rare-earth dopants, presently commercially available, as indicated in IEC 61291-1, as well as alternative optical amplifiers that can be used for single channel output power controlled operation, such as semiconductor optical amplifiers (SOA).

The object of this standard is to provide the general background for optical amplifier (OA) power transients and its measurements and to indicate those IEC standard test methods for accurate and reliable measurements of the following transient parameters:

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:

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)
