Duplex SC Plug and Duplex SC Connector | NETGEAR FS 750, FS 726

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.
