9.5.6 Amplified or Passive OADM Node Fiber-Optic Cabling
• The first Side B AD-xC-xx.x or AD-xB-xx.x card COM TX port is connected to the Side B
OPT-BST or OSC-CSM RX port.
• If a Side A OPT-PRE is present, the Side A OPT-BST or OSC-CSM COM TX port is connected to
the Side A OPT-PRE COM RX port.
• If an Side B OPT-PRE is present, the Side B OPT-BST or OSC-CSM COM TX port is connected to
the Side B OPT-PRE COM RX port.
The following rules generally apply for OADM node add/drop path cabled connections:
• AD-xB-xx.x add/drop (RX or TX) ports are only connected to the following ports:
–
4MD-xx.x COM TX or 4MD-xx.x COM RX ports
–
Another AD-xB-xx.x add/drop port (a pass-through configuration)
• 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-xx.x card, 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 all have the
same line direction).
The following rules generally apply for OADM node pass-through path cabled connections:
• Pass-through connections are only established between add and drop ports on the same band or
channel and in the same line direction.
• AD-xC-xx.x or AD-xB-xx.x add/drop ports must be connected to other AD-xC-xx.x or AD-xB-xx.x
add/drop ports (as pass-through configurations).
• Add (RX) ports must be connected to drop (TX) ports.
• 4MD-xx.x client input/output ports must be connected to other 4MD-xx.x client input/output ports.
• A Side A AD-xB-xx.x drop (TX) port is connected to the corresponding Side A 4MD-xx.x COM
RX port.
• A Side A AD-xB-xx.x add (RX) port is connected to the corresponding Side A 4MD-xx.x COM TX
port.
• An Side B AD-xB-xx.x drop (TX) port is connected to the corresponding Side B 4MD-xx.x
COM RX port.
• An Side B AD-xB-xx.x add (RX) port is connected to the corresponding Side B 4MD-xx.x COM TX
port.
Figure 9-37 shows an example of an amplified OADM node with AD-1C-xx.x cards installed.
Note Figure 9-37 is an example. Always install fiber-optic cables based on the
Cisco TransportPlanner Internal Connections table for your site.
