When I looked inside the OADM module, I don't remember seeing any
splices, but that may just be because I didn't look inside the optobox
itself.  I was under the impression that the connectors were not
pigtails spliced to the optobox fibers, but rather directly terminated
to the fibers emerging from the optobox.  I'm not sure the optobox is
meant to be opened.

So my question is, how hard is it to put a raw angled connector onto a
strand of fiber in the field without using factory pre-terminated
pigtails?  I assume the process would be the same as any other
connector: insert strand, cleave, polish, but using an angled sleeve
to polish the end at the correct angle?

Wow, that would be confusing.
