20、interface dimensions for the type LX.5 family of connectors. 2 Description The parent connector for the type LX.5 connector family is a single position plug connector set of plug/adaptor configuration which is characterized by a 1,25 mm nominal diameter ferrule. The connector includes a single coupl
21、ing latch and a ferrule spring loaded in the direction of the optical axis. The plug has a single male key, which may be used to orient and limit the relative position between the connector and the component to which it is mated. The optical alignment mechanism of the connectors is of a resilient sl
22、eeve style. 3 Interfaces The subsequent pages define the standard interfaces for the type LX.5 connector family. This document contains the following standard interfaces.

The maximum is limited by the shutter. The ferrule is movable by a certain axial compressing force, with direct contacting e
36、ndface, and therefore dimension AA is variable. Ferrule compression force must be 3,5 N to 6,0 N when the optical datum target, dimension AA is moved to the range 12,90 mm to 12,50 mm; NOTE 2 Dome eccentricity of the spherically polished endface must be less than 70 m. NOTE 3 A chamfer or radius is
37、allowed to a maximum depth of 0,5 mm from the ferrule endface; NOTE 4 These dimensional requirements apply to the finished ferrule, after all polishing procedures have been completed. NOTE 5 Dimension AM is defined as an angle between two planes: One plane, plane A, passes through the axis of the fe
38、rrule and the axis of symmetry of the key of the angled endface connector plug. The other plane, plane B, passes through the axis of the ferrule and the plane normal to the angled PC reference plane.

For a fixed sleeve the positional tolerance of dimension BU applies to both BU and A dimensions. For a floating sleeve, a gauge pin
45、inserted in the sleeve must be capable of moving freely into a position such that it is coincident with datum AA. Dimension A defines the inner diameter of the alignment feature. NOTE 2 The connector alignment feature is a resilient (split) alignment sleeve. The feature must accept a pin gauge to th
