RI-307M3 is a high-precision, field, 2-channel OTDR for applications with high requirements to the accuracy class (e.g., SCS, CATV networks, heat networks ODK systems, etc.).)RI-307M3 allows with low instrumental error (up to 3 cm) to make the following measurements on cables with lengths from 1 m to 128 km: measurement of cable lengths; measurement of distances to inhomogeneities of wave impedance or faults: breakage; low impedance defects (less than 1 kOhm); short circuit; defective soldering; defective amplifier; presence and location of taps; locked areas or areas with high humidity; couplings, cable splices; Poupin coils, broken pairs; flickering defects.Pulse reflectometer RI-307M3 is used for control during laying and operation of the following types of cable lines: copper-core communication cables; signalling and control cables; power cables; overhead cable lines; computer networks; television and radio frequency CLs.
