The coupling sleeve shall be movable toward the right-and the left-directions. These dimensions are given when the coupling sleeve is moved in its most righ
41、t-direction position. 3. The dimension J is given for the plug endface when not mated. Note that the ferrule is movable by a certain axial compression force with direct contacting end faces. and therefore the dimension J is variable. Ferrule compression force shall be 5,5 N to 6.5 N when the positio
42、n of the optical datum target from the datum X is moved in the range of 3,9 mm to 4,l mm. In addition, the dimension J shall become less than 3.25 mm with a relatively large axial compression force. 4. The dimension Q shall be negative when the outer sleeve is in the extreme left position. 5. The do

For angled polished endfaces the dome offset shall be measured not only in the nominal position of the ferrule in the plug, but also in the extreme positions while rotated within the plug.
