DLP-G70 Install Fiber-Optic Cables for an Amplified or Passive OADM Node
Note Throughout this task, west refers to Slots 1 through 8, and east refers to Slots 10 through 17.
Note Amplified OADM nodes contain OPT-PRE cards and/or OPT-BST cards. Passive OADM nodes do not.
Both contain add/drop channel or band cards.
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 connecting fiber-optic cabling for amplified or passive
OADM nodes, read the following rules for all OADM connections:
• The two sides of the OADM node do not need to be symmetrical. On each side, Cisco MetroPlanner
can create one of the following four configurations:
– OPT-BST and OPT-PRE
– OSC-CSM and OPT-PRE
– Only OSC-CSM
– Only OPT-BST
Step 2 Consult the following rules for OADM node express path cabled connections:
• TX ports should only be connected to RX ports.
• EXP ports are connected only to COM ports in between AD-xC-xx.x or AD-xB-xx.x cards that all
belong to the east side (that is, they are daisy-chained).
• EXP ports are connected only to COM ports in between AD-xC-xx.x or AD-xB-xx.x cards that all
belong to the west side (that is, they are daisy-chained).
• The EXP port of the last AD-xC-xx.x or AD-xB-xx.x card on the west side is connected to the EXP
port of the first AD-xC-xx.x or AD-xB-xx.x card on the east side.
• The OPT-BST COM RX port is connected to the nearest (in slot position) AD-xC-xx.x or
AD-xB-xx.x COM TX port.
• The OPT-PRE COM TX port is connected to the nearest (in slot position) AD-xC-xx.x or
AD-xB-xx.x COM RX port.
• If OADM cards are located in adjacent slots, the TCC2/TCC2P card assumes they are connected in
a daisy-chain between the EXP ports and COM ports as noted previously.
Purpose This task gives instructions, rules, and examples for installing fiber-optic
cables on an amplified or passive optical add/drop multiplexing (OADM)
node in a DWDM shelf.
