Optical amplifiers. Test methods - Gain transient parameters. Two-wavelength methodWhat is BS EN 61290 4 1 Gain transient parameters Two wavelength method about? BS EN 61290 4 1 is a safety standard on the two wavelength method for the gain transient parameters. BS EN 61290 4 1 applies to optical amplifiers (OAs) using active fibres (optical fibre amplifiers (OFAs)) containing rare earth dopants including erbium doped fibre amplifiers (EDFAs) and optically amplified elementary sub systems. These amplifiers are commercially available
