27、- EN 50377-8-7:2007 1 Scope 1.1 Product definition This European Standard contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements which a connector terminated with cylindrical zirconia PC ferrule and assembled singlemode resilient alignment sle

28、eve LSH-PC simplex connector set (plug/adaptor/plug), adaptor and patchcord must meet in order for it to be categorised as an EN standard product. Since different variants and grades of performance are permitted, product marking details are given in 3.5. 1.2 Intermateability Although all products co

29、nforming to the requirements of this standard will intermate, the resulting level of random attenuation performance will only be ensured 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 havi

30、ng different attenuation grades, the resulting level of attenuation can not be assured to be any better than the worst attenuation grade. The intermating of a grade C plug with a grade B plug will result in an uncertain level of random attenuation performance. Table 1 - Ensured level of random atten

31、uation Plug variant/Attenuation grade C B C C C B C B 1.3 Operating environment The tests selected combined with the severities and durations are representative of a Category C environment as described in EN 61753-1. 1.4 Reliability Whilst the anticipated service life expectancy of the product in th

32、is environment is 20 years, compliance with this standard does not guarantee the reliability of the product. This should be predicted using a recognised reliability assessment programme. 1.5 Quality assurance Compliance with this standard does not guarantee the manufacturing consistency of the produ

33、ct. This should be maintained using a recognised quality assurance programme.

The optical alignment mech

49、anism of the connectors is of a resilient sleeve style. 3.1 Plug The plug features a cylindrical full zirconia ferrule and a latched push-pull mechanism. The plug has mechanical and colour coding. 3.2 Adaptor The adaptor has a zirconia ceramic resilient alignment sleeve. The mounting style can be: i square flange - 2 hole fixing; ii square flange - side clip fixing; iii square flange - top bottom clip fixing. Covers (dustcaps) shall be provided to protect each port of the adaptor. The adaptor has a mechanic
