Add the following new clauses 4, 5 and 6:
4 SC duplex connector interfaces
The standard interfaces contained in this clause are the following:
– interface 61754-4-3: duplex plug connector interface – push/pull, PC;
– interface 61754-4-4: duplex adaptor connector interface – push/pull.
The duplex plug connector of interface 61754-4-3 has ferrules with a spherically polished
ferrule endface, and realises physical contact (PC).
The following standard interfaces are intermateable. It, however, shall be noted that in order to
obtain the designated optical performance, any plug shall be connected to a counterpart plug
whose ferrule end is polished to the same condition.

NOTE 1 – A chamfer or radius is allowed to a maximum depth of 1,2 mm from the ferrule endface.
NOTE 2 – Dimension H is given for plug endface when not mated. It is movable by a certain axial
compression force, with direct contacting endfaces, and therefore dimension H is variable. Ferrule
compression force shall be 7,8 N to 11,8 N when the dimension H is 7 mm ± 0,1 mm.
NOTE 3 – The negative dimension indicates that the position of the inside bottom plane is left-direction
relative to the reference plane.
NOTE 4 – The delatch housing shall be movable towards right and left direction. These dimensions are
given when the delatch housing is moved in its extreme right-direction position.
NOTE 5 – Dimension M should be below 0 mm, when the delatch housing is moved to its most left-
direction position.
NOTE 6 – The delatch housing may be a rigid sleeve. When two simplex plugs are retained together by a
flexible sleeve, the dimension P shall be from 8,89 mm to 8,99 mm.
NOTE 7 – Dimension BF shall be measured over a diameter of 0,25 mm around the ferrule axis. The
dome eccentricity of the spherical polished endface should be less than 50 μm.
NOTE 8 – The delatch housing may be a rigid sleeve. When two simplex plugs are retained together by a
sleeve or a clamp with a clearance, the dimension DB shall be 12,7 mm as a basic dimension.
NOTE 9 – The ferrules should be capable of taking up a common axis with the duplex adapter alignment
sleeves.
