Basics of optical network design

How can a mesh network be upgraded to transport more services?

  • A Configuring new WSS cards is the most effective way to give flexibility and network bandwidth to an existing mesh network.
  • B The Protection and Restoration Combined (PRC) mechanism can enable more bandwidth but only for the protected services.
  • C Upgrading the network to coherent transmission is the only effective way to enable more bandwidth to the existing mesh network.
  • D Upgrading link capacity and/or installing new links provides more bandwidth to the existing mesh network.
Explanation

Increasing the capacity of existing links and/or deploying additional links raises the available transport bandwidth and adds paths through the mesh, allowing more services to be carried. Coherent transmission can be one capacity-enhancement approach, but it is not the only effective one. Nokia documentation also describes increasing an in-service network’s bandwidth capacity through supported capacity upgrades.
