Chapter 3 Turn Up a Node
DLP-G65 Install Fiber-Optic Cables for OSC Link Terminations Between Two Adjacent Nodes
Step 2 Plug one end of a fiber into the west OPT-BST or OSC-CSM LINE TX connector.
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).
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 5 Plug the other end of the fiber cable into the adjacent node east OPT-BST or OSC-CSM LINE RX
connector. Repeat in the other direction (east to west, TX to RX). Always connect the west line ports to
the adjacent node east line ports.
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 6 If OSCM cards are not installed, continue with Step 7. If OSCM cards are installed on both sides of the
shelf, complete Steps a through d. If an OSCM is installed on the west side of the shelf, but not the east
side, complete Steps a and b only. If the OSCM is installed on the east side of the shelf but not the west,
complete Steps c and d only.
a. Plug one end of a fiber into the west OPT-BST OSC RX connector and the other end into west
OSCM OSC TX connector.
b. Plug another fiber into the west OSCM OSC RX connector and the other end to the west OPT-BST
OSC TX connector.
c. Plug one end of a fiber into the east OPT-BST OSC RX connector and the other end into the east
OSCM TX connector.
d. Plug another fiber into the east OSCM OSC RX connector and the other end to the east OPT-BST
OSC TX connector.
Step 7 Repeat Steps 2 and 6 at each node in the network. If this is the final node, continue with Step 8.
Step 8 Return to your originating procedure (NTP).
1 West OPT-BST LINE RX to east OPT-BST or OSC-CSM
LINE TX on adjacent node
5 East OSCM TX to east OPT-BST OSC RX

LINE RX on adjacent node
6 East OSCM RX to east OPT-BST OSC TX
3 West OPT-BST OSC TX to west OSCM RX 7 East OPT-BST LINE TX to west OPT-BST or
OSC-CSM LINE RX on adjacent node
4 West OPT-BST OSC RX to west OSCM TX 8 East OPT-BST LINE RX to west OPT-BST or
OSC-CSM LINE TX on adjacent node
