Fiber-optic cables can use many types of connectors, but the Network+ exam
is concerned only with the two major connector types: the straight-tip (ST)
connector and the subscriber (SC) connector. The ST connector is based on the
BNC-style connector but has a fiber-optic cable instead of a copper cable. The
SC connector is square and somewhat similar to an RJ-45 connector. Figure 1-24
shows the ST (the connector on the left side) and the SC (the connector on the right
side) connector types.
