DLP-G70 Install Fiber-Optic Cables for an Amplified or Passive OADM Node
• The first west AD-xC-xx.x or AD-xB-xx.x card COM RX port is connected to the west OPT-PRE
or OSC-CSM COM TX port.
The first west AD-xC-xx.x or AD-xB-xx.x card COM TX port is connected to the west OPT-BST
•
or OSC-CSM COM RX port.
The first east AD-xC-xx.x or AD-xB-xx.x card COM RX port is connected to the east OPT-PRE or
•
OSC-CSM COM TX port.
The first east AD-xC-xx.x or AD-xB-xx.x card COM TX port is connected to the east OPT-BST or
•
OSC-CSM RX port.
• If a west OPT-PRE is present, the west OPT-BST or OSC-CSM COM TX port is connected to the
west OPT-PRE COM RX port.
If an east OPT-PRE is present, the east OPT-BST or OSC-CSM COM TX port is connected to the
•
east OPT-PRE COM RX port.
Consult the following rules for OADM node add/drop path cabled connections:
Step 3
AD-xB-xx.x add/drop (RX or TX) ports are only connected to the following ports:
•
• An AD-xB-xx.x add/drop band port is only connected to a 4MD-xx.x card belonging to the same
band.
For each specific AD-xB, the add and drop ports for that band card are connected to the COM TX
•
and COM RX ports of the same 4MD-xx.x card.
The AD-xB-xx.x and 4MD-xx.x cards are located in the same side (the connected ports will all have
•
the same line direction).
Consult the following rules for OADM node pass-through path cabled connections:
Step 4
Pass-through connections are only established between add and drop ports on the same band or
•
channel and same line direction.
Only connect AD-xC-xx.x or AD-xB-xx.x add/drop ports to other AD-xC-xx.x or AD-xB-xx.x
•
add/drop ports (as pass-through configurations).
An add (RX) port is only connected to a drop (TX) port.
•
• Only connect 4MD-xx.x client input/output ports to other 4MD-xx.x client input/output ports.
• A west AD-xB-xx.x drop (TX) port is connected to the corresponding west 4MD-xx.x COM RX
port.
A west AD-xB-xx.x add (RX) port is connected to the corresponding west 4MD-xx.x COM TX port.
•
• An east AD-xB-xx.x drop (TX) port is connected to the corresponding east 4MD-xx.x COM RX
port.
An east AD-xB-xx.x add (RX) port is connected to the corresponding east 4MD-xx.x COM TX port.

– Another AD-xB-xx.x add/drop port (a pass-through configuration)
shows an example of an amplified OADM node with AD-1C-xx.x cards installed.
Figure 3-14 is an example. Always install fiber-optic cables based on the Cisco MetroPlanner
Internal Connections table for your site.
