Fibre optic interconnecting devices and passive components - Performance standards Part 121-3: Simplex and duplex cords with singlemode fibre and cylindrical ferrule connectors for category U - Uncontrolled environment
|Publication Date:||1 April 2012|
|ICS Code (Fibre optic interconnecting devices):||33.180.20|
This part of IEC 61753 specifies the test requirements for finished cable assemblies for use as patchcords, work area cords and equipment cords for applications in a 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.
1 Low wavelength limit depends on maximum cabled fibre cut-off wavelength specification.
