This document specifies a method of measuring the semi loose effect of a semi loose cable. Pull proof optical contacts are used. The optical contact (ferule) is longitudinally moving to preserve the optical performance even when cables are pulled. Consequently, the buffered fiber is moving beneath the strength members (called semi loose effect). This document is describing a test methodology to assess the quality of the cable when contact is pulled or pushed.
