PON has become the gold standard for fixed optical access, with over a billion terminations deployed globally. As ITU-T and IEEE drive new standards to push bit rates even further, the discussion now includes 200 Gb/s per wavelength using PM-QAM and coherent detection.
🔍 Why Coherent Transceivers in PON?
Beyond just increasing bit rates, coherent PON can deliver:
âś… Longer reach for extended access networks
âś… Higher splitting ratios, supporting more ONUs per PON tree
âś… Greater network layer flexibility, optimizing metro and access integration
🌍 ALLEGRO’s Vision
Our theoretical scalability analysis explores an end-to-end all-optical convergence of metro and PON segments—enabled by coherent transmission and ROADM-based interconnection. By pushing the span budget to new limits, we aim to redefine how metro and PON networks seamlessly integrate.
