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.
