Sub-Nanosecond Clock and Data Recovery in an Optically-Switched Data Centre Network
ECOC(2018)
Abstract
We demonstrate a clock and data recovery technique that achieves u003c625ps locking time for 25.6Gb/s-OOK and show its robustness under worst-case data centre temperature variation. The locking time was improved by 12×, making nanosecond optical switching viable in data centres.
