DEVICE FOR TESTING CABLE TO BE LAID INSIDE ROOMS AND STATIONARY OBJECTS Russian patent published in 2017 - IPC G01M11/08 

FIELD: cables.

SUBSTANCE: invention relates to cable industry and concerns a cable testing to be laid inside rooms and stationary objects. For the testing sample 1 of an optic cable (OC) in the form of coil 2 (OC length in the coil is 10–15 m) is placed on platform 3 of the vibration bench and is rigidly secured to its surface. Before and after platform 3 of the vibrobenchthe tested OC is attached to posts 4 to form two freely hanging semi-loops simulating the OC input-output sections between fixed points (the OC air input from a column to a building) and characterized by the most probable deformation. Sample is fixed on platform 3 on both sides of the vibrobench with clamps 5. Cable on both sides is reeled into two coils 6 with an internal diameter of not less than 20 of the nominal outer diameters of the cable or is wound onto drums with a neck diameter similar to the coil diameter. Ends of tested sample 1 are respectively connected with radiator 7 and receiver 8 with an optical power meter by optical connectors 9.

EFFECT: technical result is creation of a device for testing a cable, which enables to determine parameters-criteria of its usability, such as integrity of optical fibres and shells of the cable, attenuation coefficient of optical fibres and other parameters depending on the optical cable design.
