Cabling and Specifications
4-port OC-3c/STM-1 ATM Line Card Power Specifications
The 4-port OC-3c/STM-1 ATM line card provides the Cisco 12000 series router with four 155-Mbps
OC-3c/STM-1c duplex SC single-mode or multimode SONET/SDH ATM interfaces. Table 5 lists the
power ratings and distances of these interfaces. The actual distance in any given case depends on the
quality of the fiber attached to the transceiver.
4-port OC-12c/STM-4c ATM Line Card Power Specifications
The 4-port OC-12c/STM-4c ATM line card provides the Cisco 12000 Series Router with four 622-Mbps
ATM interfaces. Table 6 lists the power ratings and distances of these interfaces. The actual distance in
any given case depends on the quality of the fiber attached to the transceiver.
8-port OC-3c/STM-1 ATM Line Card Power Specifications
The 8-port OC-3c/STM-1 ATM line card provides the Cisco 12000 Series Router with eight 155 Mbps
ATM interfaces. Table 7 lists the power ratings and distances of these interfaces. The actual distance in
any given case depends on the quality of the fiber attached to the transceiver.
