One terabit optical ethernet

Coming to a point-of-presence near you in the near future.

From the link:

Researchers with the Terabit Optical Ethernet Center (TOEC) at the University of California, Santa Barbara (UCSB) are aiming for 1 Terabit Ethernet over optical fiber — 1 trillion bits per second — by 2015 and 100 Terabit Ethernet by 2020. Partnering with TOEC as founding industry affiliates are Google Inc., Verizon, Intel, Agilent Technologiesand Rockwell Collins Inc.

Ethernet is constantly evolving, but soon — in as little as five years, according to some estimates — it won’t be able to keep up with the speed and bandwidth required for applications like video and cloud computing, and distributed data storage. “Based on current traffic growth, it’s clear that 1 Terabit per second trunks will be needed in the near future,” says Stuart Elby, Vice President of Network Architecture for Verizon.

Current Ethernet technologies can’t be pushed much past 100 Gigabits per second — the speed that’s beginning to be implemented now — mainly because of the amount of power needed to run and cool the required systems, says Daniel Blumenthal, Professor of Electrical and Computer Engineering at UCSB and Director of TOEC. Large data centers can consume as much power as a small city. New generations of Ethernet need to be much more energy-efficient and cost-effective, or the power problem will limit Ethernet development, crippling the growth of key U.S. industries and technologies.
