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 sleeve LC-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 3.6. 1.2 Intermateability 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 the resulting level of attenuation cannot be assured to be any better than the worst attenuation grade. Therefore, the intermating of a Grade C plug with a Grade B plug will result in an uncertain level of random attenuation performance.
