Hi Aaron,Are there situations when angled connectors are not to be used? Are they 'safe' or even recommended for any kind of DWDM application?To my knowledge APC is always better than PC connectors. APC are used to eliminate back reflections. Due to the angled connector reflections are sent mostly towards the cladding and not the core and therefore.
Indeed. I have always held the idea that APC connectors induced greater chromatic and/or polarization mode dispersion -- yet can't find any resources that claim so, nor does that fit in with my working mental model of how light propagates. Just something I picked up during the hellish days of trying to deploy 10GbE before it was cool; now I'd like to know if it is grounded in any science (-: Thanks aaron
