Last year’s OFC write-up focused on the divergent flavors of PON for supporting 5G xHaul. The divergence in PON types continues, with this year's OFC write-up focusing on the readiness of the ecosystem along with initial test results and proposals by operators.


  • The divergence in PON solutions for transport is putting a strain on the ecosystem, encompassing subcomponent vendors, optical module vendors, equipment vendors, and operators.

Features and Benefits

  • Examines the various PON solutions being proposed for 5G xHaul.
  • Assesses the impact of the divergent PON types on the ecosystem.

Key questions answered

  • Which types of PON are being considered for wireless backhaul, midhaul, and fronthaul? What is leading to the divergence?
  • What are the advantages of reusing the FTTH network for 5G xHaul?
  • Which player in the ecosystem can push for convergence?
