What is BS EN 61753-121-2 - Fibre optic interconnecting devices and passive components about?
BS EN 61753 is a series of 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 61753-121-2 specifies the test requirements for cords including reference cords used in a controlled (Category C) environment according to IEC 61753-1, where the connectors already comply with the Category C requirements of IEC 61753-1. The tests selected are a subset of the connector tests from IEC 61753-1 appropriate for requalification with additional requirements relevant to cords and the connector/cable interface.
The relevant requirements for the mechanical interface of connector sets are covered by BS EN 61753-121-2. The relevant requirements for the optical interface of connector sets are covered by IEC 61755 (all parts). The relevant requirements for the performance of connector sets are covered by IEC 61753 (all parts). The relevant requirements for fibres are covered by IEC 60793-2-50. The relevant requirements for cables for cords are covered by IEC 60794-2- 50.
Who is BS EN 61753-121-2 - Fibre optic interconnecting devices and passive components for?
BS EN 61753-121-2 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 61753-121-2 - Fibre optic interconnecting devices and passive components?
Fibre optic interconnecting devices and passive components architecture implement a point-to-multipoint topology in which a single optical fibre serves multiple endpoints by using unpowered (passive) fibre optic splitters to divide the fibre bandwidth among the endpoints. BS EN 61753-121-2 discusses the cords that consist of simplex or duplex fibre optic cable terminated at each end of the cable with single-mode fibre optic connector plugs with cylindrical ferrules. The operational wavelength range is between 1 260 nm and 1 625 nm. Short length cords are used as test samples as the attenuation of the cord and the temperature cycling performance will be affected by longer lengths of cable. It is important that any qualification of a cord whose length is greater than 5 m takes these factors into account.
Patchcords, work area cords, equipment cords and reference cords (called "cords" in subsequent text) defined according to BS EN 61753-121-2 are terminated cable assemblies with optical connector plugs at each end. The length, unless otherwise specified, is defined as being between the end faces of the connector plugs. Cords, except reference cords, can be of any cable length. Reference cords have a length between 2 m and 5 m. All tests and measurements have been selected from BS EN 61753-121-2 for connectors and from the cable test procedure. Additional requirements to certain tests are given in BS EN 61753-121-2. Using BS EN 61753-121-2 you can specify the test requirements for cords including reference cords used in a controlled (Category C) environment.
