Комплети конектора и компоненте за повезивање који се користе у оптичким комуникационим системима – Спецификације производа – Део 14-1: Симплекс и дуплекс савитљиви каблови направљени од симплекс утикача са цилиндричном ферулом, који користе мономодна B-652 или B-657 оптичка влакна према EN 60793-2-50, за категорију C у складу са EN 61753-1
Connector sets and interconnect components to be used in optical fibre communication systems - Product specifications Part 14-1: Simplex and duplex cords made from simplex plugs with cylindrical ferrules, using EN 60793-2-50 single-mode B-652 or B-657 fibre for Category C according to EN 61753-1
1.1 Product definition
This document contains the initial, start of life, dimensional, optical, mechanical and environmental performance requirements that an assembled single mode cord with cylindrical ferruled connectors will 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
Where the products conforming to the requirements of this document are intermateable, the resulting level of random attenuation performance will be 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 any better than the worst attenuation grade of the individual plugs.
Intermating 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 IEC 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 is predicted using a recognized reliability assessment program.
1.5 Quality assurance
Compliance with this standard does not guarantee the manufacturing consistency of the product. This is expected to be maintained using a recognized quality assurance program.
