24、sional, optical, mechanical and environmental performance requirements of a Terminal Equipment Boxes for the FTTX networks. The Terminal Equipment Box will house the ONT/CPE (electronics) and it protects the optical fibres, splices and connectors from direct contact with the user. Optionally it can

25、contain the network test interface, the power supply and the batteries. The performance of the electronics, power supply or batteries are not part of this document. These are covered by another EN document, EN 50700. This specification contains the initial, start of life optical, mechanical and envi

26、ronmental performance requirements of the optical fibre termination in a Terminal Equipment Box, in order for it to be categorized as an EN standard product. 1.2 Operating environment The tests selected combined with the severity and duration is representative of indoor and outside plant for above g

27、round environments defined by: EN 61753-1 Category C Controlled environment 1.3 Reliability 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 us

28、ing a recognised reliability assessment programme. 1.4 Quality assurance Compliance with this specification does not guarantee the manufacturing consistency of the product. This should be maintained using a recognised quality assurance programme. 1.5 Allowed fibre types All EN 60793-2-50 fibres can

29、be stored in the Terminal Equipment Box with a minimum storage radius of 20 mm (up to a length of maximum 2 m). Smaller storage radii down to 15 mm are possible with the EN 60793-2-50 B6_a fibre types, but in this case the reduction in mechanical reliability should be taken into account (see Annex A
