Cables and Connectors
Use single-mode (for short-, intermediate- or long-reach configurations) optical fiber cable to connect
your router to a network or to connect two OC12 POS line card-equipped routers back to back. For
SONET/SDH single-mode optical fiber connections, use two simplex SC-type cables (see
Figure 1-8 ),
or one duplex SC-type cable (see Figure 1-9 ).

Note
For maximum cable lengths between stations, see Table 1-1 on page 1-5 . Single-mode optical fiber
cables for the OC12 POS line card are not available from Cisco Systems; they are available from
commercial cable vendors.
Attach one pair of simplex fiber cables between the line card and the device to which the line card is
connected. Observe the receive (RX) and transmit (TX) cable relationship shown in
Figure 1-10 .
Note
For important laser safety information, see the “Laser Safety” section on page 2-5 .
Warning Invisible laser radiation can be emitted from the aperture of the port when no cable is
connected. Avoid exposure to laser radiation and do not stare into open apertures.
