Fibre optic interconnecting devices and passive components - Connector optical interfaces - Part 2-4: Connection parameters of non-dispersion shifted single-mode physically contacting fibres - Non-angled for reference connection applications
Abstract
This part of IEC 61755 defines the dimensional limits of an optical interface for reference connections necessary to meet specific requirements for fibre-to-fibre interconnection of non-angled single-mode reference connectors intended to be used for attenuation measurements in the field or factory. Two different grades for reference connections are defined in this document. The use of each of these grades depends on the application and on the targeted attenuation measurement uncertainty. The singlemode reference connections are terminated to IEC 60793-2-50 class B fibre with restricted mode field diameter (MFD). The geometrical dimensions and tolerances of the specified reference connections have been developed primarily to limit the variation in measured attenuation between multiple sets of two reference connectors, and therefore to limit the variation in measured attenuation between randomly chosen reference connectors when mated with connectors in the field or factory.
