What is BS EN IEC 61753‑111‑09 about?
BS EN IEC 61753 is a series on fibre optic interconnecting devices and passive components. Fibre optic interconnecting devices and passive components is a fibre-optic  telecommunications technology for delivering broadband network access to end customers. BS EN IEC 61753‑111‑09 closures define the requirements for standard optical performance under a set of specified conditions. BS EN IEC 61753‑111‑09 contains the minimum tests, test severities and measurement requirements that a sealed fibre optic closure need to meet in order to be categorized as meeting the BS EN IEC standard for category S – Subterranean.
BS EN IEC 61753‑111‑09 contains a series or a set of tests and measurements with clearly stated conditions, severities and pass/fail criteria. The set of tests is intended to be a basis to prove the product’s ability to satisfy the requirements of a specific application, market sector or user group.
Products having the same classification from one manufacturer that satisfy BS EN IEC 61753‑111‑09 will operate within the boundaries set.
Who is BS EN IEC 61753‑111‑09 for?
BS EN IEC 61753‑111‑09 on fibre optic interconnecting devices and passive components is useful for:
- Telecommunication equipment and component manufacturers
- Design engineer
- Quality control personnel
- Research and development facilities
Why should you use BS EN IEC 61753‑111‑09?
Testing and inspection of optical fibre devices and components are essential safeguards for digital communications. Sealed closure for optical fibre cables provides mechanical protection and environmental sealing to the spliced cables. BS EN IEC 61753‑111‑09 guides you about reliability testing which is the subject of a separate test schedule, where the tests and severities selected are such that they are truly representative of the requirements of this reliability test program.
BS EN IEC 61753‑111‑09 guides you about optical performance testing of fibre as the mechanical and environmental performance of a fibre splice is vital to the optical cabling system. Conformance to performance standards demonstrates that a product has passed a design verification test.
BS EN IEC 61753‑111-09 provides requirements for the tests and measurement methods for testing of sealed closure optical fibre which helps you to determine the ability of an optical-fibre cable to withstand and recover from the effects of a compressive force.
