Hi SFP modules will generally have UPC connectors. You therefore need to use cables with UPC at one end and APC at the other end. If you use a APC-APC cable you will have 3-6 dB of optical loss. If it is a short connection and you are out of correct cables, it will usually work. On longer connections you need the extra power budget. As to where to buy, I will suggest fiberstore.com.

APC wins!
My real question is surrounding the connection on the SFPs themselves.
In general terms are the LC connectors on SFPs considered UPC or APC?
If the answer is UPC and if I am inheriting and/or building a network of single mode fiber with APC SC connectors, then is the best practice to use LC UPC to SC APC fiber jumpers?
If so, can anyone point me to a source for said jumpers that is (1) quick and (2) good?
Any thoughts on the same idea of mismatched fiber jumpers connector types to use on OLMs and OLSs? OTDRs? The concern here is to use the best possible fiber connector types (e.g. APC or UPC) when connecting lasers to my OSP fiber which uses APC with consideration to the optimal connector type for the laser transceiver.
My thoughts are to use fiber jumpers with UPC connectors on the laser side with APC on and throughout the OSP, but if it should be purely APC everywhere, then that is what I need to know.
Thanks!
