This document provides information on different types of physical terminations for networking including optical fiber connectors like SC and LC, copper connectors like RJ-45 and RJ-11, and small form-factor pluggable (SFP) modules. It lists common optical and copper termination standards and their applications for technologies such as 1000Base-SX/LX, 1000Base-T, and 10Gig X2.
