I have seen cwdm Add/Drop muxes that fit in a splice case. May fit what you need.

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.
