Journal and Invited Conference Papers Published on Low Power and Latency Transceivers

A paper describing the CONfigurable Transceiver Energy uSage Toolkit (CONTEST) has been accepted for publication in IEEE Transactions on Very Large Scale integration (VLSI).

CONTEST, a collaboration between Dr Philip Watts, of the Optical Networks Group at UCL, and the Cambridge Computer Laboratory, provides an open source design to promote future work in low power, low latency transceivers for future optical switching networks in high performance servers and data centres.  The paper is now available on IEEExplore as an early access article.

The latest results from CONTEST were presented in an invited paper at the international Conference on Advanced technologies for Communications (ATC) held in Hochiminh City, Vietnam during October 16th - 18th.  The work showed that 4 wavelength WDM links can have 79% lower power consumption than serial NRZ links for a 25Gb/s aggregate bit rate.  Power gating of SERDES circuits (the highest contributor to transceiver power) was also demonstrated with restoration times of <1 ns and restoration energies of <47 pJ for bit rates up to 25 Gb/s.
