[OR]-2-2 the optical reflectometer Producer: Privately held company “the institute of information texnologies” Optical reflectometer [OR]-2-2 is intended for attenuation measuring before the optical fibers (ОВ) and their connections, length OV distance to the place of damage. Field of application: installation and operation [VOSP], production OV and optical cables. Instrument can work before the field and laboratory conditions. Reflectometer [OR]-2-2 consists of base block and change optical blocks for the measurement multimode and one-mode OV beyond different wavelengths.

Control besides the work of reflectometer, the working and mapping the results of measurement is accomplished with the aid of Personal Computer of the type Of notebook, which can enter into delivery set.

Convenient software makes it possible to determine all required characteristics OV, to simultaneously analyze on the display Personal Computer several reflectogram, to preserve on the disk and to read based on it measurement data, to print out them on the printer. Regime “template” makes it possible to substantially reduce the time of analysis and traveling papers of optical cable line. Reflectometer ensures storage and readout of reflectogram before the size Of bellcore.

The measurement of the parameters of electrical communication cables can be achieved with the aid of the additional plug-in package.

Instrument is executed before the durable metal housing, which corresponds to standard IP-65.
