Deployment Topologies

This chapter describes examples of deployment topologies that utilize the Routed Optical Networking architecture.

Routed Optical Networking supports the following deployment topologies.

  • Metro/Regional–This topology is used for shorter reach metro use cases and longer regional use cases.

  • Long Haul–This topology is used for distances greater than 400 km. The QDD-400G-ZR-S optic has a maximum reach of 120 km. Longer distances require the use of QDD-400G-ZRP-S optics.

The Routed Optical Networking solution architecture or network design is the same for in network (core, aggregation, or DCI). The only differentiating factor is the hardware that is used for any deployment. The following topologies are examples of specific hardware deployments.

Port Connections

To build this topology, connect the cables in the following sequence:

  1. On the Cisco 8201-1 and Cisco 8201-2 routers:

    1. Align the QDD-400G-ZR-S transceiver module in front of 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-64-C (MD-64-1) module. In this sample topology, we use channel ID 7, which corresponds to a frequency of 195.65 THz (a wavelength of 1532.29 nm).
