An SC/APC fiber optic adapter is a passive mechanical interface used to join two SC connectors that have angled physical contact (APC) ferrules, typically polished at 8°. If you work with single‑mode optical networks—FTTH, PON, CATV, 5G fronthaul—you will run into the SC/APC fiber optic adapter (sometimes called an SC/APC coupler) almost immediately. By linking two connectors precisely, fibre optic adapters allow the light sources to be transmitted at most and. Canovate's SC fiber optic adapters are compatible with all fiber types including single-mode (9/125 microns) and multi-mode (50/125 microns) fibers. Canovate components comply with both major industry standards – ANSI/TIA/EIA 568-B. Though small, the. SC Adapters Fiber Optic Connectors are available at Mouser Electronics. RS offer a wide selection of fibre optic adapters.
