OC12 Packet Over SONET Line Card Installation and Configuration

OL-3437-01

Chapter1 Overview

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).

Figure 1-8 Simplex SC-Type Cable and Connector

Figure 1-9 Duplex SC-Type Cable and Connector

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.
