Optical amplifiers - Part 7: Four wave mixing effect in optical amplifiers

IEC/TR 61292-7:2011(E) applies to optical amplifiers (OAs) using active fibres and waveguides, containing rare-earth dopants, currently commercially available. It provides guidance on crosstalk caused by the four-wave mixing (FWM) effect. The object of this technical report is to provide introductory information for understanding of the crosstalk issue raised by the FWM effect.
