DLP-G68 Install Fiber-Optic Cables for a Line Amplifier Node
Note Throughout this task, west refers to Slots 1 through 8, and east refers to Slots 10 through 17.
Step 1 Refer to the Cisco MetroPlanner Internal Connections table (see Table 3-1 on page 3-3) for your site
when completing connections. Before you begin the line amplifier node connections, read the following
rules:
• Line amplifier node layout allows all combinations of OPT-PRE and OPT-BST and allows you to
use asymmetrical card choices in west-to-east and east-to-west configurations. For a given line
direction, you can configure the four following possibilities:
–
Only preamplification (OPT-PRE)
–
Only booster amplification (OPT-BST)
–
Both preamplification and booster amplification (where a line amplifier node has amplification
in at least one direction)
–
Neither preamplification nor booster amplification
• If a west OPT-PRE card is installed:
–
The west OSC-CSM or OPT-BST COM TX is connected to the west OPT-PRE COM RX port.
–
The west OPT-PRE COM TX port is connected to the east OSC-CSM or OPT-BST COM RX
port.
• If a west OPT-PRE card is not installed, the west OSC-CSM or the OPT-BST COM TX port is
connected to the east OSC-CSM or OPT-BST COM RX port.
• If an east OPT-PRE card is installed:
–
The east OSC-CSM or OPT-BST COM TX port is connected to the east OPT-PRE COM RX
port.
–
The east OPT-PRE COM TX port is connected to the west OSC-CSM or OPT-BST COM RX
port.
• If an east OPT-PRE card is not installed, the east OSC-CSM or OPT-BST COM TX port is connected
to the west OSC-CSM or OPT-BST COM RX port.
Figure 3-12 shows an example of a line amplifier node with cabling.
Note Figure 3-12 is an example. Always install fiber-optic cables based on the Cisco MetroPlanner
Internal Connections table for your site.
Purpose This task installs fiber-optic cables on a line amplifier node in a DWDM
shelf.
