Chapter 3 Overview: Cisco 7600 Series Router Shared Port Adapters
1-Port OC-12c/STM-4 ATM SPA Overview
For single-mode and multimode optical fiber connections, you can use either a duplex LC-type cable (see
Figure 3-21) or two simplex LC-type cables, one for transmit (TX) and one for receive (RX).
Use single-mode (for intermediate- or long-reach configurations) or multimode optical fiber cable to
connect your router to a network or to connect two 1-Port Channelized OC-12/STM-4 SPA-equipped
routers back to back.
Long-range SFP optical transceiver modules (for long-reach configurations) cannot be connected
back-to-back without using an attenuator between the two of them.
