Network Connection Considerations
Figure 4-53 Simplex SC Connector
For SONET/SDH single-mode connections, use the single-mode (ST2) connector
(bayonet-style twist-lock). (See Figure 4-54.)

Note The ATM network processor module for the Cisco 4000 series router uses identical
duplex SC connectors for single-mode and multimode SONET connections. The front
panels are similar in appearance. The best way to tell the difference is by the yellow laser
warning label on the front panel of the single-mode module, or by the specific part number
visible on the upper surface of all PLIMs.
