适用范围

Product definition This European Standard covers passive optical fibre street cabinets for use in outside plant environments under category A according to EN 61753-1. This document contains the dimensional@ optical@ mechanical and environmental performance requirements of an installed passive optical fibre street cabinet@ in order for it to be categorized as an EN standard product. The street cabinet is a protective housing containing modular fibre management systems with splice trays for various fibre separation levels and connector mounting plates. The street cabinet may contain one or more of the following: ? storage and routing of fibre and cable; ? uncut (looped) fibre and cable storage; ? splice trays; ? adaptors and connectors; ? passive optical components (optical power splitters and wavelength division multiplexers). Street cabinets can also contain active optical components (amplifiers@ converters@ power supplies)@ but these applications are not part of this document. Operating environment The tests selected@ combined with the severity and duration@ are representative of outside plant above ground environments defined by EN 61753-1 Category A: Aerial environment. Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years@ compliance with this European Standard does not guarantee the reliability of the product. This should be predicted using a recognized reliability assessment programme. Quality assurance Compliance with this European Standard does not guarantee the manufacturing consistency of the product. This should be maintained using a recognized quality assurance programme. Allowed fibre and cable types This street cabinet standard accommodates EN 60793-2-50 single-mode fibres and EN 60793-2-10 A1a and A1b multimode fibres and all EN 60794 series optical fibre cables with various fibre capacities@ types and designs as long as fitting in the cabinet does not contravene the fibre or cable minimum bend radius.
