PC ferrule and assembled singlemode resilient alignment sleeve
SC-PC simplex connector set (plug/adaptor/plug),
Since different variants and grades of performance are permitted.
Although all products conforming to the requirements of this European 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, 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 an uncertain level of random attenuation performance.
A simplex plug can be connected in a duplex adaptor without degrading its level of performance.
The tests selected combined with the severities and durations are representative of a category U environment described in EN 61753-1.
Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this specification does not guarantee the reliability of the product. This should be predicted using a recognised reliability assessment programme.
Compliance with this specification does not guarantee the manufacturing consistency of the product. This should be maintained using a recognised quality assurance programme.
