Challenges of IM-DD and Digital Empowerment from End-to-End to Unleach System Cabability
15 August 2019
We review the propagation of light in single mode fibers and summarize the principles of operation of current commercial fiber-optic transceivers relying on power modulation and detection, which unnecessarily constrain these systems. We review a few recent proposals employing DSP techniques to significantly uplift performance and capabilities.
