This document 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 categorised as an European standard product.
The street cabinet is a protective housing containing a modular fibre management system 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;
- adapters 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.
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.
Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this document does not guarantee the reliability of the product. This should be predicted using a recognised reliability assessment programme.
Compliance with this document does not guarantee the manufacturing consistency of the product. This should be maintained using a recognised quality assurance programme.
Allowed fibre and cable types
This street cabinet standard allows EN 60793-2-50 single-mode fibres and EN 60793-2-10 A1-OM1 to A1-OM5 multimode fibres to be used and is suitable for all EN 60794 series optical fibre cables with their various fibre capacities, types and designs as long as fitting in the cabinet does not contravene the minimum bend radius.
