Cisco Cisco 12000 Series 1-Port OC-48 STM-16 POS SDH ISE Line Card

Attach the line card cable-management bracket to the line card as follows:

Position the cable-management bracket over the front of the line card faceplate.

Insert and tighten the captive screw(s) to secure the bracket to the line card.

Starting with the bottom port on the line card, connect each interface cable to the intended port.

For multiport line card cable-management brackets, carefully wrap the cables with the supplied Velcro 
strap. (See 

Figure 14

.) 

For single-port line card cable-management brackets, carefully press the interface cable onto the cable 
clip. (See 

Figure 15

.) Avoid any kinks or sharp bends in the cable.

The following sections provide specifications for the channelized and electrical interface line card:

The SONET specification for fiber-optic transmission defines two types of fiber: single-mode and 
multimode. Signals can travel farther through single-mode fiber than through multimode fiber. 

The maximum distance for installations is determined by the amount of light loss in the fiber path. If 
your environment requires the signal to travel close to the typical maximum distance, you should use an 
optical time domain reflectometer (OTDR) to measure the power loss. 

The following sections describe the power budget and signal specifications for the optics used in the 
channelized line cards:

The 1-port channelized OC-12/STM-4 (DS1/E1) ISE 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. The transmitter section of this device uses a laser with full IEC 825 and
