What is BS EN 61758-1— Interface standard for closures about?
BS EN 61758-1 is the first part of an international standard that focuses on fibre optic interconnecting devices and passive components.
BS EN 61758-1 provides general information and guidance about closures. BS EN 61758-1 includes references, general closure and interface descriptions and definitions.
BS EN 61758-1 defines the following general interfaces for closures:
- Interface to cables
- Interface to FMS
- Interface to parts other than FMS or cables
- Interface to external sittings (pits, manholes etc.)
BS EN 61758-1 allows both single-mode and multi-mode fibre to be used and covers all IEC standard optical fibre cables as listed in Clause 2, with their various fibre capacities, types, and designs. It covers all types of closures.
Who is BS EN 61758-1— Interface standard for closures for?
BS EN 61758-1 on interface standard for closures is relevant to:
- Manufacturers of interface closures
- Manufacturers of optical fibre cables
- Manufacturers of testing apparatus
- Fibre optic technicians
- Fibre optic installers
- Testing authorities
Why should you use BS EN 61758-1— Interface standard for closures?
Closures are used for all external housings except outdoor cabinets, whereas, enclosures are used for both indoor housing cabinets, cases, distribution frames and outdoor cabinets.
BS EN 61758-1 is an informative specification that provides you with guidance for general closure, terminology related to it and interface descriptions for the same. BS EN 61758-1 describes all the technicalities of the closures such as functional requirements, closure safety, grounding interface, cable to closure interface, etc., that enables users to provide housing for a fibre management system, including cable element storage, and ancillary passive or active components or other functional parts to build an optical node. BS EN 61758-1 talks about active components and passive components of closure interface closure to FMS interface, closure interface to external sitting etc., that provides you with a management system for the external environment, e.g., subterranean chambers, aerial poles, and street cabinets as well as environmental and mechanical protection.
Overall, BS EN 61758-1 is useful as it provides guidance on the interface closures, which can be helpful for your business.
