Duplex SC Plug and Duplex SC Connector
The duplex SC connector connects stations, hubs, and switches that support the
1000BASE-SX fiber interface. Each fiber link needs a clearly defined, external
crossover. In other words, the transmit port of one interface must be wired to the
receive port of the opposite interface and vice versa. Fiber cables must be connected in
this manner to transmit and receive data.
The duplex SC connector and duplex SC plug are illustrated in Figure B-2.

Warning: Fiber optic equipment can emit laser or infrared light that might
injure your eyes. Never look into an optical fiber or connector port. Always
assume that fiber optic cables are connected to a light source.
