Cabling and Specifications
1-Port Channelized OC-12/STM-4 (DS3) Line Card Power Specifications
The 1-port channelized OC-12/STM-4 (DS3) line card is only available in a single-mode,
intermediate-reach configuration providing a full-duplex 622.08-Mbps 1310-nm laser-based
SONET-compliant interface. Table 9 lists the power budget and signal specifications of the 1-port
channelized OC-12/STM-4 (DS3) line card. The actual distance in any given case depends on the quality
of the fiber attached to the transceiver.
2-Port Channelized OC-3/STM-1 (DS1/E1) Line Card Power Specifications
The 2-port channelized OC-3/STM-1 (DS1/E1) line card is only available in a single-mode,
intermediate-reach configuration providing a full-duplex 155-Mbps 1310-nm laser-based
SONET-compliant interface. Table 10 lists the power budget and signal specifications of the 2-port
channelized OC-3/STM-1 (DS1/E1) line card. The actual distance in any given case depends on the
quality of the fiber attached to the transceiver.
Line Card Interface Cables
Channelized line cards with optic ports use fiber-optic cables. The line cards with T3, DS3, and E3 ports
use T3 cables. Each of these cables are described in the following sections:
• Fiber-Optic Cables, page 25
• T3 Cables, page 27
Fiber-Optic Cables
Use a single-mode optical-fiber interface cable to connect a line card with an optical port in your
Cisco 12000 Series Router to another line card or add/drop multiplexer (ADM).
Note Fiber cables are not available from Cisco Systems. They can be purchased from cable vendors. If the
plug is supplied with a dust cover, remove it before trying to connect it to the line card port.
The subscriber connector (SC) cable connectors are used with channelized line cards with optic ports
(Figure 16).
