2 Description
Add, after the existing paragraph, the following new text:
This part of IEC 61754 defines the standard interface dimensions of active device receptacles
for the type SC connectors. The receptacles are used to retain the connector plug and
mechanically maintain the optical datum target of the plugs at a defined position within the
receptacle housings.
3 Interfaces
Add, after Interface 4.2: simplex adaptor connector interface – push/pull, the following new
standard interfaces:
Interface 4-X1: simplex active device receptacle interface – for angled PC connector plug
Interface 4-X2: simplex active device receptacle interface – for PC connector plug
Interface 4-X3: duplex active device receptacle interface – for angled PC connector plug
Interface 4-X4: duplex active device receptacle interface – for PC connector plug

NOTE 1 An example of a mechanical stop feature is shown in figure 7a. A mechanical stop feature is required
in order to bring the fibre tip to the optical datum target. Due to the ferrule tip geometry variations, some means
of providing a mechanical reference stop for all types is required. The mechanical stop feature incorporated into
the reference should be capable of maintaining the optical datum target of both the fibre and the receptacle
within the clearances specified in table 7d depending upon the application.
NOTE 2 This may be a structure as shown by a dashed line shown in figure 7a.

NOTE 3 The connector alignment feature is a resilient sleeve. The feature accepts a gauge pin to the
centre of the receptacle with a force of 2,9 N to 5,9 N. The centre of the receptacle is defined by the right
side position of the dimension H. The measurement is performed using a single gauge pin.
