This part of IEC 61300 describes a test to quantitatively assess the capability of fibre optic connector terminated fibre assemblies to withstand static tensile loads without uncoupling of the connector, physical damage to the assembly or degradation of optical performance. This test is intended to apply to fibre assemblies using any of the following: Media type 1: reinforced jacketed cordage of any diameter, Media type 2: cable with 900 m buffer coating that may or may not be reinforced or Media type 3: connectors terminating fibre with 250 m coating. The contents of the corrigendum of January 2015 have been included in this copy.
