DESCRIPTION

The OK6-13 Work Station provides the verification of the following parameters of fiber-optic communication measurement instruments:

– emission power and stability of generators, sources and testers;

– absolute and relative power levels measurement error of power meters, testers, reflectometers and attenuation meters;

– attenuation and attenuator’s setting error;

– reflectometer distance and attenuation scale measurement error and definition of its dead band;

– spectral characteristics of fiber-optic communication measurement instruments.

PRINCIPLE OF OPERATION

Principle of operation:

– comparison of power value of the signal alternatively applied from a stable power source to the Work Station Power Meter and Power Meter under test;

– spectral decomposition of the signal applied from the source under test using

the MDR-203 Monochromator and measurement of spectra characteristics of the photodetector under test by comparing them with the reference photodetector;

– reflectometric-based formation of two electrical pulses with the regulated time delay

with their further conversion to optical pulses.
