  • central conductor wire (usually copper) surrounded
    by an insulating material, which, in turn, is surrounded by a braided metal shield. The cable is referred to as coaxial (coax for short) because the center
    wire and the braided metal shield share a common axis or centerline

SC connector

Three subtypes
- APC 8-degree angle to the curved end, lowering signal loss further

  • UPC polished extensively for a superior finish. These reduce signal loss significantly over PC connectors
