ISO/IEC 14763-3:2006+A1:2011 specifies systems and methods for the inspection and testing of optical fibre cabling designed in accordance with ISO/IEC 11801 or equivalent standards. The test methods refer to existing standards-based procedures where they exist. It replaces ISO/IEC TR 14763-3, first edition, published in 2000, and constitutes a technical revision. It incorporates innovations and recent developments including guidance in the proper use of uni-directional and bi-directional OTDR testing, the three-jumper method as default test method, fibre end-face inspection and criteria for scratches, return loss values for SC and non-SC connectors and the normative use of reference connectors. However, the most substantial change is the application of the 2 parameters which are used to determine the two repeatable multimode launch conditions "modal power distribution and "coupled power ratio. This consolidated version of ISO/IEC 14763-3 consists of the first edition (2006) and its amendment 1 (2009). It bears the edition number 1.1. The technical content is therefore identical to the base edition and its amendment and has been prepared for user convenience. A vertical line in the margin shows where the base publication has been modified by amendment 1. Additions and deletions are displayed in red, with deletions being struck through. This consolidated version consists of the first edition (2006) and its amendment 1 (2009). Therefore, no need to order amendment in addition to this publication.
