Description of BS EN 50377-14-1:2018 20181.1 Product definition This standard contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements for an assembled single mode cord with cylindrical ferruled connectors to meet in order for it to be categorized as an EN standard product. Since different variants and grades of performance are permitted, product marking details are given in 4.5 and Clause 5. 1.2 Intermateability of the plugs Although all products conforming to the requirements of this standard are meant to intermate, the resulting level of random attenuation performance will only be expected in accordance with Table 1. The intention is that this will be true irrespective of the manufacturing source(s) of the product. When intermating plug variants having different attenuation grades as specified in EN 61755 1, the resulting level of attenuation cannot be ensured to be any better than the worst attenuation grade. The intermating of a grade C plug with a grade B plug will result in a grade C level of random attenuation performance. Table 1 — Ensured level of random attenuation Plug variant / Attenuation grade Plug 2 C B Plug 1 C C C B C B 1.3 Operating environment The tests selected combined with the severities and durations are representative of an EN 61753 1 Category C environment. 1.4 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this standard does not guarantee the reliability of the product. This should be predicted using a recognized reliability assessment programme. 1.5 Quality assurance Compliance with this standard does not guarantee the manufacturing consistency of the product. This should be maintained using a recognized quality assurance programme.
