Coherent transceivers have become a mature and widely used technology in optical transport networks, and attention is now turning to how these capabilities can extend to future PON generations. Meeting the high link budget requirements of access networks while maintaining tight cost and power constraints for optical network units introduces significant engineering and commercial pressures. Operators must evaluate scalability, interoperability and time‑sensitive performance to justify investment decisions. Enabling fast and reliable burst‑mode operation adds further complexity as networks push toward lower latency and higher efficiency. These factors make DSP innovation central to ensuring sustainable ROI for next‑generation coherent PON deployments.
In this session, Ognjen Jovanovic will examine methods for enabling low‑complexity burst‑mode DSP that supports coherent transmission in time‑division multiplexed PON environments. He will outline challenges such as rapid DSP convergence, stringent power budgets and upstream burst detection and discuss how these constraints shape system‑level decision metrics, including capacity, overhead and return on capital. He will also share insights from experimental demonstrations that show how scalable implementations can reduce operational risk in next‑generation access networks. Attendees will gain a clearer view of the practical considerations shaping coherent PON evolution.
