DIN EN 50411-3-8:2016-10

This European Standard specifies the dimensional, 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 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 environmental performance requirements of the optical fibre termination in a Terminal Equipment Box, in order for it to be categorized as an EN standard product. The standard contains the minimum requirements, the details and the test severities for 17 different tests. The standard thus provides investment security for manufacturers and users and gives testing laboratories and manufacturers defined specifications for testing. The responsible committee is DKE/UK 412.7 "LWL-Verbindungstechnik und passive optische Komponenten" ("Fibre optic interconnecting devices and passive optical components") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
