ÖVE/ÖNORM EN 50377-14-1:2012-05

Заменен
Connector sets and interconnect components to be used in optical fibre communication systems - Product specifications - Part 14-1: Cords with IEC 60793-2-50 singlemode category B1.1 and B1.3 fibre for category C (english version)
1.1 Product definition

This standard contains the initial, start of life dimensional, optical, mechanical and environmental
performance requirements that an assembled singlemode patch cord with cylindrical ferruled connectors
shall 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 3.4
and Clause 4.

1.2 Intermateability of the plugs

Although all products conforming 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 having different attenuation grades as specified in EN 61755-1, the resulting
level of attenuation cannot 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 a grade C level of random attenuation
performance.

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 recognised
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 recognised quality assurance programme.
