Fibre organisers and closures to be used in optical fibre communication systems - Product specifications Part 2-10: Sealed fibre splice closures type 2, category G, for FTTH optical distribution networks
 N EN 50411-2-10

Annotation

Product definition

This specification contains the dimensional, optical, mechanical and environmental performance requirements of a fully installed splice closure for use in optical distribution networks at ground level (category G) in order for it to be categorised as an EN standard product. This type of sealed closure is intended for easy and/or frequent opening and closing in FTTH distribution and drop cable networks.

NOTE The sealing performance requirements and test severities of these closures are selected to obtain an IP 67 intrusion protection performance as defined in EN 60529.

Operating environment

The tests selected combined with the severity and duration are representative of an outside plant for ground level environment defined by EN 61753-1, category G: ground level. This corresponds with: - operating temperature range: -40 °C to +65 °C; - direct exposure to non weather protected outside plant conditions; - deployment at ground level up to 3 metres above ground level; - additionally to the category G environment, a deployment till 1 metre below ground level is added. Direct buried applications are allowed, however additional protection will be required when the locations are intended for passage of cars or other heavy vehicles.

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 using a recognised reliability assessment programme.
