We are looking into doing cableTV/HFC distribution on campus, and fiber runs for HFC typically run APC connectors to avoid reflectance on the analog HFC signal where it is significant. We we're looking at converting some existing data UPC to APC for existing runs, and on the new ones either do a parallel split (UPC and APC) or just stay uniform (research seems to indicate APC is the winner). In asking some other groups (EDU LAN managers) I've heard both extremes... stick with all APC (and jumper APC-to-UPS on gear to data terminations), and I've heard the exact opposite (UPC is fine, just jumper UPC to APC at the terminations). The last time I asked here, the consensus seemed to be APC was ok, or else do parallel splits. My best understanding is that going APC across the board, and just using jumpers (APC to UPC) at the data ends should be fine, and I'm leaning in that direction. Are there any significant issues there? Do APC terminations "confuse" a data OTDR since you're now missing the expected reflections? Other issues? Before the RFQs go out on the fiber expansion, I'd like to have a clear goal in mind here :) Any reason NOT to go APC for the installed fiber plant and just adjust the terminating jumpers based on the endpoint targets? Thanks (again), Jeff
