The calibration laboratory for optical testers, power meters and Optical Time Domain Reflectometers (OTDR) is described. There are stabilized laser sources with stabilization of radiation, power meter, attenuators, facilities for measurement of wavelengths, optical generator, calibrated measures of optical length of long fibers (about 1 km) at this laboratory. The laboratory can be used for calibration of power meters and OTDR of all types.
