In order to meet the system requirements of the cable TV(CATV) industry and
other high-speed digital systems, 3M has developed a single-mode FC 8° angle-
polished connector to minimize reflections to a mean of -80 dB.
Worldwide, there are two defacto standards for FC/APC connectors; a 2.0 mm
nominal connector key and a 2.15 mm connector key are in widespread use. Long
term, it is expected that the 2.0 mm nominal connector key will dominate the
marketplace.
Specially designed, tight key couplings are available for both the 2.0 mm and
2.15 mm connectors which offer premium optical performance. The angled end
finishes of the connectors could also mate with the standard FC couplings with
an additional 0.15 dB insertion loss.
