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_Modul... 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. [snip]

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 Thilo
Thanks, Chuck

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.
