1.1 Product definition
This European Standard contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements that a Factory Polished Field Terminated (FPFT) single mode simplex connector set (plug adaptor plug) will meet in order for it to be categorized as an EN standard product.
The FPFT is designed for either fusion or mechanical splice methods. The performance is specified for the mated combination between a FPFT plug and an EN standardized plug from the EN 50377 series (configuration 1) or between two FTFP plugs (configuration 2). The fibre specified inside the FPFT plug in this European Standard is standard single mode fibre with low water peak as specified as B1.3, which is field mated to B1.3 fibre or bend insensitive single mode fibre specified as B6_a1 or B6_a2 in EN 60793-2-50. Mixing standard and bend insensitive fibres in a connection potentially causes a considerable intrinsic attenuation due to mode field diameter mismatch. These connectors are intended to be for an indoor installation. The connectors are terminated onto reinforced cables according to EN 60794-2-50 with outer diameter greater than 0,9 and up to 3 mm.
Since different variants and grades of performance are permitted, product marking details are given in 3.6.
