ATM Cabling

For single-mode or multimode SONET connections, connect the ﬁber cable to the SC-style

receptacle on the module front panel. The SONET SC-duplex connector is shipped with a

dust plug. Remove the plug by pulling on the plug as you squeeze the sides of the connector.

For SONET/SDH multimode connections, use one multimode duplex SC connector (see

Figure 4-52) or two single SC connectors. (See Figure 4-53.)
