Chapter 3 Turn Up a Node
DLP-G67 Install Fiber-Optic Cables for a Terminal Node
• A terminal site has only one side (as compared to a hub node, which has two sides). The terminal
side can be either east or west.
• The terminal side OPT-BST or OSC-CSM card COM TX port is connected to the terminal side
OPT-PRE COM RX port or the 32DMX-O COM RX port.
• The terminal side OPT-PRE COM TX port is connected to the terminal side 32DMX-O COM RX
port.
• The terminal side 32MUX-O COM TX port is connected to the terminal side OPT-BST or
OSC-CSM COM RX port.
Step 2 Plug one fiber cable end into the desired RX port.
Step 3 Route the fiber cable on the card faceplate through the fiber clip on the faceplate, if provided. (Fiber clips
are factory-attached to the faceplates of 32MUX-O, 32DMX-O, OSCM, OPT-PRE, and OPT-BST
cards.)
Step 4 Route the fiber cable through the cable-routing channel and cutout on the appropriate side of the shelf
assembly, as necessary (Figure 15-35 on page 15-37).
Step 5 As needed, route slack fiber-optic cable around the round cable retainers in the fiber-storage tray
(Figure 15-38 on page 15-40).
Caution When you close the fiber-storage tray, the cables must not be pinched, and the cable bend radius must
be equal to or greater than the minimum radius that is recommended in your site specifications. As you
route each cable through the fiber-storage tray, make sure that adequate cable slack remains.
Step 6 Route the fiber cable out either side of the fiber-storage tray as necessary.
Step 7 Plug the other end of the cable into the desired TX port.
Note Cards display an SF LED after the OSC terminations are created (see the “NTP-G38 Provision
OSC Terminations” procedure on page 3-84) if transmit and receive fibers are not connected
correctly. For example, an RX port is connected to another RX port or a TX port is connected to
another TX port.
Step 8 Repeat 2 through 7 until you have connected the nodes according to the site plan.
Step 9 Return to your originating procedure (NTP).
