INTRODUCTION

Intent

The intent of this bend test is to determine the degree of cable degradation that will occur if the cable is statically bent around a corner of a given radius. Cables that are most likely to be subject to this type of bend in actual installation are building entrance cables, flexible cables and buried service type cables.

Potential failure modes

Potential failure modes for this test include:

a) Optical performance degradation.

b) Cracking, splitting, or tearing of cable jacket.

c) Cable jacket deformation resulting in a permanent degradation of protection to the optical core of the cable.
