TT-JR300 Series Optical Fiber Cable Bend (Winding) Testing Machine is intended to determine the ability of an optical fibre cable or cable element to with stand bending around a test mandrel such as U bend and S bend.
The sample is wrapped in a close helix around the mandrel at a uniform rate. Sufficient tension is applied to ensure that the sample contours the mandrel. The sample then is unwrapped. A cycle consists of one wrapping and one unwrapping.
