  • Why: Marginal for the PM, but PON's evolution beyond 10G (25G/50G time- and wavelength-domain options) is the access-side bookend of the optics roadmap they track — the same traffic-growth forces pushing 800G in the DC push higher split ratios and rates at the edge.
  • What: A recap of PON fundamentals, where standards and deployments stand today, and how PON evolves beyond 10G to support higher speeds and increasing traffic demands. (from abstract only)
  • How: Standards/deployment survey of next-generation PON options and their capacity implications.
  • Where applicable: Access/broadband networks; vendor-presented (Ciena), and pitched as a recap-plus-roadmap, so treat the evolution claims with the usual vendor filter. Skippable if your remit doesn't touch access networks.
