Scope and object This part of IEC 61290-4 applies to erbium-doped fibre amplifiers (EDFAs) and optically amplified elementary sub-systems. It applies to OAs using active fibres (optical fibre amplifiers@ OFAs)@ containing rare-earth dopants. These amplifiers are commercially available and widely deployed in service provider networks. The object of this part of IEC 61290-4 is to provide the general background for EDFA transients and related parameters@ and to describe a standard test method for accurate and reliable measurement of the following transient parameters: ? Channel addition emoval transient gain overshoot and transient net gain overshoot ? Channel addition emoval transient gain undershoot and transient net gain undershoot ? Channel addition emoval gain offset ? Channel addition emoval transient gain response time constant (settling time)
