What is BS EN 61753-121-3 - Fibre optic interconnecting devices and passive components about?
BS EN 61753 is a series on fibre optic interconnecting devices and passive components. Fibre optic interconnecting devices and passive components do not require electrical-to-optical or optical-to-electrical conversion during their operation. BS EN 61753-121-3 specifies the test requirements for finished cable assemblies for use as patch cords, work area cords and equipment cords for applications in an uncontrolled (U) environment according to IEC 61753-1, where the connectors already comply with the Category U requirements of IEC 61753-1. The assemblies consist of simplex or duplex fibre optic cable terminated at each end of the cable with non-angled (PC) or angled (APC) polished single-mode fibre optic connectors with cylindrical ferrules. The wavelength of operation is between 1 260 nm 1 and 1 625 nm.
The relevant requirements for mechanical and optical connectivity systems are covered by mechanical and optical interface standards IEC 61754 series and IEC 61755 series respectively. The relevant requirements for connector sets are covered by IEC 61753 series. The relevant requirements for cable are covered by IEC 60794-2-50.
Who is BS EN 61753-121-3 - Fibre optic interconnecting devices and passive components for?
BS EN 61753-121-3 on fibre optic interconnecting devices and passive components is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use BS EN 61753-121-3 - Fibre optic interconnecting devices and passive components?
Fibre optic interconnecting devices and passive components are widely used by people as a promising solution for modern access to telecommunication networks. Patch-cords, work area cords and equipment cords (called cords in subsequent text) defined according to BS EN 61753-121-3 are terminated cable assemblies with optical connectors. The cord comprises a cable and terminates fibre optic connectors on each end. The length, unless otherwise specified, is defined as between the end faces of the connectors. All tests and measurements have been selected from the IEC 61300 series for connectors and from the cable test procedure outlined in IEC 60794-1-2.
Additional requirements for certain tests are given in BS EN 61753-121-3. No deviation from the specified test method is allowed. Unless otherwise specified, all tests are carried out at the ambient temperature as specified. This visual examination is made to ensure that the captivation or attachment of a cable sheath to a connector will withstand all climatic and mechanical tests required in BS EN 61753-121-3. The purpose of the test as described in BS EN 61753-121-3 is to determine the influence of a side load applied to a cord assembled with connector strain relief. Fibre optic cords withstand side loads during optical transmission without degradation of the optical performance. BS EN 61753-121-3 shows in a more realistic manner the deformation of the connector strain relief. Using BS EN 61753-121-3 you can specify the test requirements for finished cable assemblies for use as simplex or duplex fibre optic cable.
