UNE-EN 50377-4-3:2023

1.1 Product definitionThis document contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements which a connector terminated with cylindrical zirconia 9° angled PC ferrule and assembled singlemode resilient alignment sleeve SC-APC simplex connector set (plug/adaptor/plug), adaptor and patchcord meet in order for it to be categorized as an EN standard product. This document is intended to replace CECC 86 265-803.Since different variants are permitted, product marking details are given in 4.6.1.2 IntermateabilityProducts conforming to the requirements of this document are intended to intermate, and it is expected that the specified level of random attenuation performance will be met. The intention is that this will be true irrespective of the manufacturing source(s) of the product.1.3 Operating environmentThe tests selected, combined with the severities and durations, are representative of a category OP environment described in EN IEC 61753-1.1.4 ReliabilityWhilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this document does not guarantee the reliability of the product. This is expected to be predicted using a recognized reliability assessment programme.1.5 Quality assuranceCompliance with this document does not guarantee the manufacturing consistency of the product. This is expected to be maintained using a recognized quality assurance programme.
