As the second issue in 2020 of the Optical Communications and Networks Series (OCNS), this series selects articles that cover interesting advances on devices, systems and networks regarding optical communications and networking. We are pleased to witness active innovations in this area, which will make the data exchange and processing in the future Internet more adaptive, application- aware, and cost-eff ective. For this issue, we have selected four contributions that address (i) interleaved data converter architectures for future high-speed fiber optical communications; (ii) improved modulation designs for visible light communications; (iii) new bandwidth allocation schemes for supporting green fog integration in next-generation optical access networks; and (iv) a techno-economic study on optical network disaggregation employing open-source software business models.
