Coherent detection has revolutionized optical communications since its introduction in long-haul, high-speed systems. Now, as demand for higher data rates grows in access networks and data center interconnects, the industry is exploring how coherent technology could replace traditional IMDD-based solutions.
Standardization bodies like ITU-T are already discussing what comes next beyond 50G-PON. While a 100G/𝜆 solution might push IMDD to its limits with advanced PAM-4 modulation and DSP, going beyond 100G/𝜆 will likely require a shift to coherent detection.
Our latest work at Allegro presents a single carrier filtering model designed for Metro-Access scenarios—bridging the gap between today’s IMDD networks and the coherent-driven future.
We’re excited about the potential of this approach to enable the next generation of high-speed, efficient, and scalable optical networks.
Let’s connect and discuss! What are your thoughts on the role of coherent detection in access networks? 👇
