STRUCTURE OF WORKING STANDARD
• measuring unit of average power of optic emission;
• portable computer;
• set of fiber optic cables and elements;
• kit of photoelectric measuring converters;
• measuring unit of time responses of optic emission sources;
• measuring unit of spectral characteristics of optic emission receivers.

PURPOSE
Working standard РЭСМ-В is designed for reproducing, storing and transmitting the unit of aver-age power of optic emission, calibration and verification of measuring instruments of average power at fixed length of волн излучения – calibration wavelength. Сalibrated and verificated measuring instruments include average power meters, wattmeters, optical testers, optical emis-sion sources, and fiber-optic attenuators for fiber-optic transmission systems. Verification can be carried out according to GOST 8.720-2010 and Р 50.2.070-2009.
