According to AT&T in Sweden, the 1237J lightwave transmitter should
mate with any ST connector having specified ferrule diameter.
They are not sure whether there should be an polymer alignement insert,
or if the alignement should be ferrule to metallic body. They are
looking into the matter.
It seems likely that there is something wrong in the manufacturing
process, since standard ST connctors fit badly in the transmitter.

Could someone knowledgeable please respond...!
Current findings is that several other links using DEFXS-BA indeed
do work, even though the connector is NOT firmly aligned within the
connector receptable. After checking at the Royal Inst. of Tech we
even got our own link to loop, by placing the flat surface of the
two SC shells against a glass plate(to get z-axis ok) and adjusting the
distance and position until the yellow led started blinking.
Obviously the transmitter to st connector interface is not so critical
since a the transmitter connector on a good working link can we wiggled
enough so you can feel the lack of alignment easily. The subjective
feel is that the gap is tent's of mm rather than thousand's ( which
you'd not be able to feel)
I always thought that SMF equpment required the outmost mechanical
presision. How come this works anyway?
