OT-2-4 Multichannel Optical Tester

The OT-2-4 is designed for measurement of attenuation change in optical fibers and cables, passive optical components under mechanical and temperature testing.

The tester consists of two modules:

a laser source;

a multichannel power meter.

The instrument provides simultaneous measurement of optical power levels in each optical channel (dBm), measurement of attenuation change (dB), calculation of fiber attenuation coefficient change (dB/km).

The usage of an external reference optical channel enables high measurement accuracy and long-term stability of the instrument.

The OT-2-4 operating control, representing, storing and data processing are provided by an IBM PC under the Windows95/98/NT (software screenshot).
