Katharine Schmidtke is responsible for Optical Technology strategy at Facebook. She obtained Katharine
a Ph.D. in non-linear optics from Southampton University in the UK and completed post-doctoral Schmidtke
research at Stanford University. She has over 20 years’ experience in the Opto-Electronics
industry including positions at New Focus, JDSU (now Lumentum), and Finisar Corporation. Technical Sourcing
Manager,
Increasing Datacenter Bandwidth: A Technology or a Manufacturing Issue?
Optical Strategy
The scale of optics deployments at hyperscale datacenters is redefining Packaging as a new
focus. Optical technology is no longer restricted to a niche telecommunications application, but Facebook (USA)
is being deployed at increasingly larger volumes in data centers. As optical technology finds
applications in interconnecting not just switches but also servers, the scale will experience a
step function that will drive innovation in integration and packaging to solve thermal challenges
and improve manufacturability, and reliability.

Magnus Herrlin is a member of the High Tech Group at Lawrence Berkeley National Laboratory Magnus Herrlin
where he manages a diverse portfolio of energy efficiency projects in data centers. Magnus is
also President of ANCIS Incorporated, a consultancy providing thermal and energy solutions for Lawrence Berkley
data centers. Prior to establishing ANCIS, he served ten years as Principal Scientist with Bell National Laboratory
Communications Research where he led efforts in optimizing energy and cooling efficiency of
electronic equipment rooms. Magnus holds a Ph.D. in Building Services Engineering from the
Royal Institute of Technology, Stockholm, Sweden.

Immersion Cooling of Electronics and Related Data Center Research at LBNL:

A large amount of energy is consumed to cool electronic equipment in data centers. Two-phase
immersion cooling has the capacity to substantially reduce the energy requirement for
high-performance computing data centers. This methodinvolves immersing the electronic
equipment in a non-conductive liquid that changesphase from a liquid to a gas when heated. In
2016, Lawrence Berkeley National Laboratory completed a demonstration project, and we will
share some of the most important findings. Related data center research at LBNL includes
developing innovative ways of packaging energy-saving measures for quick and inexpensive
implementation. The focus has been to approach hard-to-reach markets with great potential for
reducing the cooling energy, such as smaller data centers. There are tremendous opportunities
to save energy in this segment but also tremendous non-technical barriers. We will present
some of the results from our research and also provide some initial thoughts on removing the
barriers.
