Hey guys,
I would like to know whether or not the LC connector is fragile or less
reliable than its SC and ST counterparts. I've heard from a few
technicians that it breaks relatively quickly, is this true? Could you
please state why it would be preferable to SC if at all? Thanks alot :)

Michael

I've not had lots of experience with the LC, but LC makes SC look a bit of
an anomoly, in the reliabaility stakes.

The LC plugs in to it's socket more firmly and securely, whereas the SC
types might *look* as if they're plugged in, but they're not quite.

The bigger SC connectors are easier to disconnect from their fibre patch
lead, I find.

LC connector has been proven very reliable. There were some first
generation batches that got out with lousy latches that fell off and
problems like that, but they should be gone now. It really depends on
what you are connecting anyway. If you are connecting directly to
high density computer or switching ports, they all have LC now
anyway. Many FO modems and such still use SC. For me, it,s just been
about the right end for the job- no reliability concern. Having siad
that, techs should really train on fiber at least a little before
installing. Copper use in the cable plant and EMS floor manufacturing
can ingrain techniques that simply do not apply to, or kill a fiber!
(bending, crimping, cut and re-term, etc.)
