Overview

This section explains how to build a point-to-point Routed Optical Networking topology using Cisco NCS 1010 nodes. It describes required modules, wiring, node roles, and follow-up configuration tasks.

Topology diagram

This topology diagram illustrates the setup for point-to-point networks using NCS 1010 nodes.

Topology components

You need this hardware to build this topology:

  • Cisco NCS 1010 devices

  • NCS1K-MD-32O-C modules

  • QDD-400G-ZR-S transceivers

  • LC/LC cables

  • Cisco 8201 routers

For more information, see Hardware components.

Port connections

Use this sequence to connect the cables and build this topology:

  1. On the Cisco 8201 routers:

    1. Align the QDD-400G-ZR-S transceiver module with the transceiver socket opening in Port 20. Then, carefully slide the transceiver into the socket until the transceiver comes in contact with the socket electrical connector.

    2. Holding the pull-tab, seat the transceiver in the module’s transceiver socket fully until it clicks.

    3. Attach an LC/LC fiber immediately to the QDD-400G-ZR-S transceiver module.

    4. Connect the other end of the LC/LC fiber to the corresponding bulkhead adapter on the front panel of the NCS1K-MD-32O-C (MD-32-O-C) module. In this sample topology, we use a frequency of 196.1 THz (1528.77 nm).

  2. Connect an LC/LC fiber from the COM-TX port of the MD-32-O-C module to the A/D 2 RX port of the OLT-R-C module in NCS 1010–1.

  3. Connect an LC/LC fiber from the COM-RX port of the MD-32-O-C module to the A/D 2 TX port of the OLT-R-C module in NCS 1010–1.

  4. Connect an LC/LC fiber from the LINE RX port of the OLT-R-C module in NCS 1010–1 to the LINE 0 TX port of the ILA-2R-C module in NCS 1010–2.

  5. Connect an LC/LC fiber from the LINE-0 TX port of the OLT-R-C module in NCS 1010–1 to the LINE 0 LINE RX port of the ILA-2R-C module in NCS 1010–2.

  6. Connect an LC/LC fiber from the LINE 2 LINE RX port of the ILA-2R-C module in NCS 1010–2 to the LINE 0 TX port of the OLT-R-C module in NCS 1010–3.

  7. Connect an LC/LC fiber from the LINE-2 TX port of the ILA-2R-C module in NCS 1010–2 to the LINE RX port of the OLT-R-C module in NCS 1010–3.

  8. Connect an LC/LC fiber from the A/D 2 RX port of the OLT-R-C module in NCS 1010–3 to the COM-TX port of the MD-32-O-C module.

  9. Connect an LC/LC fiber from the A/D 2 TX port of the OLT-R-C module in NCS 1010–3 to the COM-RX port of the MD-32-O-C module.
