Optical Fiber Horizontal Tensile Testing Machine

Model: UTOF35-TH, IEC 60794-1-21 Method E1: Tensile performance

Optical Fiber Horizontal Tensile Testing Machine is suitable for testing the mechanical character of tensile performance of optical cables within the specified tensile load (usually the load allowed during installation), i.e., to determine the attenuation changes in the optical fibers, the strain of the optical fibers, and/or the relationship between the strain of the optical cable and the tensile load. 

General introduction

Optical Fiber Horizontal Tensile Testing Machine is suitable for testing the mechanical character of tensile performance of optical cables within the specified tensile load (usually the load allowed during installation), i.e., to determine the attenuation changes in the optical fibers, the strain of the optical fibers, and/or the relationship between the strain of the optical cable and the tensile load. Can use for the OFC and ADDS cable,

Key Features

  • Main features
  • Standard reference

This testing machine uses computer control, servo motor drive, and precision ball screw transmission for loading, with measurement via a precision load sensor signal. It features smooth loading, accurate measurement, rapid control response, and various control modes, allowing for convenient and precise digital calibration of load and elongation. It also includes full-load protection and position protection.
