What is BS EN IEC 61755‑6‑2 - Fibre optic interconnecting devices and passive components about?
BS EN IEC 61755 is a series on fibre optic interconnecting devices and passive components. is a fibre optic telecommunications technology for delivering broadband network access to end customers. BS EN IEC 61755‑6‑2 defines the dimensional limits of an optical interface for reference connectors necessary to meet specific requirements for fibre-to-fibre interconnection of nonangled polished multimode reference connectors with cylindrical ferrules intended to be used for attenuation measurements in the field or factory.
One grade of reference connector is defined in BS EN IEC 61755‑6‑2. The reference connector is terminated to selected IEC 60793-2-10:2015 A1a fibre. The geometrical dimensions and tolerances of the specified reference connector 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.

Why should you use BS EN IEC 61755‑6‑2 - 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 IEC 61755‑6‑2 currently only specifies one performance grade. However, the construction of BS EN IEC 61755‑6‑2 allows inclusion for other grades in the future, if necessary. The performance of the grade for physical contact (PC) non-angled polished reference connectors detailed is listed in BS EN IEC 61755‑6‑2.
Optical reference connectors are connectors manufactured with restricted dimensional tolerances on dimensions that contribute to the lateral and angular offset of such optical connections. These connectors are mainly used for attenuation measurement purposes and are considered as part of the measurement setup. The goal is to strongly reduce the measurement uncertainty. The attenuation uncertainties due to the reference connectors are defined in BS EN IEC 61755‑6‑2. The performance of an optical interface is not only determined by the alignment accuracy of the optical datum targets of two mating fibres, but also by any fibre parameter mismatches. There are three conditions affecting the alignment of two optical datum targets those are lateral offset, angular offset, and longitudinal offset. BS EN IEC 61755‑6‑2 discusses parameters influencing the lateral and angular offset of the optical fibre axes, parameters influencing the longitudinal offset of the optical fibre axes, parameters influencing the fibre-to-fibre intrinsic attenuation and parameters that govern the connector end face deformation and control the physical contact of two mated connectors. Using BS EN IEC 61755‑6‑2 you can define the dimensional limits of an optical interface for reference connectors necessary to meet specific requirements for fibre-to-fibre interconnection of nonangled polished multimode reference connectors with cylindrical ferrules intended to be used for attenuation measurements in the field or factory.
