2-Channel CWDM Add/Drop with SC/APC connectors

Years ago I was able to purchase 2-Channel CWDM Plug-In 1-Wavelength
Optical Add/Drop Multiplexors from Finisar with SC/APC connectors on
them, even though they normally only make the SC/PC version shown
here:

FWSF-OADM-1-xx-SC

http://www.finisar.com/products/passives/MUX-DEMUX/CWDM_OADM-1_Plug-in_Module

but they won't do the SC/APC version for me now.

Does anyone know of a good alternative? There are lots of options for
modular/rack mount 2-Channel CWDM Add/Drops that have SC/PC or LC/PC
connectors made for data networks. There are also lots of options for
1-Channel SC/APC or LC/APC modules made for CATV applications. But
I'm having trouble finding 2-Channel versions with APC connectors that
I can use with data equipment + CATV transmission on the same ring.

I know I could combine two separate 1-Channel OADMs, but I prefer the
integrated, modular solution. A bonus would be to find an alternative
that fits in my existing Finisar 2-slot 1U chassis.

In any case, I'm open to hearing about all options. Actually, I
already have the 1490nm OADM in the SC/PC version, and I suppose I
could cut off the connectors re-terminate with SC/APC and replace the
bulkhead connectors with the green ones. My preferred fiber
contractor doesn't have experience with terminating APC connectors
though. Is it that much harder to terminate the angled connectors?

Thanks,
Chuck

for cwdm ADM i dont, sorry. our supplier just has regular multiplexers.

no - its just a different type of pigtail, but adding another splice, will
increase the insertion loss slightly.

we once ordered a cwdm splitter box at a different than usual place - as
always with sc/apc connectors.
the supplier changed the pigtails to accomodate our request. unfortunatly he
didnt change the bulkheads, which was less than helpfull.

kind regards

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.

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