Optical Fiber Cable Tensile Testing Machine - Outdoor Cable

IEC-60794-1 Method E1, EN 187000 method 501, EIA/TIA-455 no. 33

Torontech's TT-OFCT-OD Optical Fiber Cable Tensile Testing Machine - Outdoor Cable is designed in accordance to IEC-60794-1 Method E1 for tensile testing of outdoor Optical Fiber Cables, this measuring method applies to optical fiber cables which are tested at a particular tensile strength in order to examine the behavior of the attenuation and/or the fiber 

elongation strain as a function of the load on a cable which may occur during installation. This method is intended to be non-destructive (the tension applied shall be within the operational values).

The cable length under test is 150 meters, Additional cable length is needed to connect the fibers to be tester. The apparatus consists of an attenuation measuring apparatus, typically an OTDR supplied by customer. A fiber elongation strain measuring apparatus based on dispersion testing equipment. A specially designed tensile test machine capable of tensioning 150 meters of optical cable in six legs of 25 meters each. The machine is equipped with a motor for controlled tensioning and a load cell for measuring the actual tension applied on the cable.

Cable is wound in the machine over appropriately sized sheaves. The cable ends extend to reach the measuring instruments. A pre-determined number of fibers within the cable are concatenated by fusion splicing. Typically, two sets of fibers are used, one will serve to measure attenuation change and the other serves for elongation monitoring.

After all initial measurements and calibration are carried out, the cable is pulled at a specified rate until a pre-attenuation and fiber length are measured.

This process may involve several tensile levels in order to characterize the entire tensile behavior of the cable, or be carried out only at the defined maximum allowed tension level.

Successful quality is tested when fiber cable is under load the fiber attenuation is not increased more than a predetermined value, typically 0.05dB over fiber length measured, and fiber cable is elongated more than a pre-determined value over its initial length. The allowed elongation under installation load is typically 0.25%
