PD IEC PAS 63267 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. PD IEC PAS 63267‑3‑31 defines certain dimensional limits of a flat PC rectangular polyphenylene sulphide (PPS) ferrule optical interface to meet specific longitudinal offset requirements for fibre-to-fibre interconnection. Ferrules made from the material specified in this PAS are suitable for use in categories C, U, E, and O as defined in IEC 61753-1. Ferrule interface dimensions and features are contained in IEC 61754 (all parts), which deals with fibre optic connector interfaces.
PD IEC PAS 63267‑3‑31 on fibre optic interconnecting devices is useful for:
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. This PAS as described in PD IEC PAS 63267‑3‑31 defines the dimensional limits of flat PC rectangular ferrules with a single row of 12 fibres. The fibre centres are spaced with a nominal alignment pitch of 0,25 mm. Interface variant, which identifies nominal ferrule cross-section.
The performance of a multimode flat PC rectangular ferrule optical interface is determined by the accuracy with which the optical datum targets of two mating ferrules are aligned with each other. There are three conditions affecting the alignment of the optical datum targets: lateral offset, angular offset, and longitudinal offset. Using PD IEC PAS 63267‑3‑31 you can define the dimensional limits of a flat PC rectangular polyphenylene sulphide (PPS) ferrule optical interface.
