The broadband access industry has grown rapidly in the past 30 years, enabling high-speed internet access for billions of people worldwide. To meet the increasing demand for capacity and speed, the industry is working on developing a 100 Gbps passive optical network (PON). This paper examines the feasibility of a specific coherent PON physical layer that aligns with existing PON channel management protocols. The analysis considers cost, optical budget, system throughput, latency, jitter, and the potential for coherent PON to replace point-to-point fiber solutions in various applications.
