Low Power DSP-Based Transceivers for Data Center Optical Fiber Communications

By Radha Nagarajan, SVP and CTO, Optical and Copper Connectivity Business Group

As the volume of global data continues to grow exponentially, data center operators often confront a frustrating challenge: how to process a rising tsunami of terabytes within the limits of their facility’s electrical power supply – a constraint imposed by the physical capacity of the cables that bring electric power from the grid into their data center.

Fortunately, recent innovations in optical transmission technology – specifically, in the design of optical transceivers – have yielded tremendous gains in energy efficiency, which frees up electric power for more valuable computational work.

Recently, at the invitation of the Institute of Electrical and Electronics Engineers, my Marvell colleagues Ilya Lyubomirsky, Oscar Agazzi and I published a paper detailing these technological breakthroughs, titled Low Power DSP-based Transceivers for Data Center Optical Fiber Communications.
