Tbps

(redirected from Optochip)

Tbps

(TeraBits Per Second, TeraBytes Per Second) One trillion bits or bytes per second. Tbps is a measurement that prior to the 21st century was unthinkable. As 40 and 100 Gbps Ethernet become the norm for high-speed backbones, terabit-per-second ratings will become common in the future. See space/time, Gbps and Mbps.


The Holy Optochip
In 2012, IBM introduced an optical chipset that transfers data at 1 Tbps. Designed for short-range transmission (less than 500 feet) in a multimode fiber array, the CMOS chip has 48 holes (top) that allow access to the 24 photodiode receivers and 24 VCSEL transmitters as seen from the back (bottom).

IBM (NYSE: IBM) scientists will report on a prototype optical chipset, dubbed "Holey Optochip", that is the first parallel optical transceiver to transfer one trillion bits one terabit of information per second, the equivalent of downloading 500 high definition movies.
"Reaching the one trillion bit per second mark with the Holey Optochip marks IBM's latest milestone to develop chip-scale transceivers that can handle the volume of traffic in the era of big data," said IBM Researcher Clint Schow, part of the team that built the prototype.
Using a novel approach, scientists in IBM labs developed the Holey Optochip by fabricating 48 holes through a standard silicon CMOS chip.
Consistent with green computing initiatives, the Holey Optochip achieves record speed at a power efficiency (the amount of power required to transmit a bit of information) that is among the best ever reported.
Technical Aspects of the Holey Optochip Parallel optics is a fiber optic technology primarily targeted for high-data, short-reach multimode fiber systems that are typically less than 150 meters.

IBM (NYSE:IBM) announced on Thursday that its scientists will today report at the Optical Fiber Communication Conference in Los Angeles on a prototype optical chipset, dubbed "Holey Optochip", that is the first parallel optical transceiver to transfer 1TB of information per second, the equivalent of downloading 500 high definition movies.
The Holey Optochip was created by fabricating 48 holes through a standard silicon CMOS chip.
The Holey Optochip illustrates that high-speed, low-power interconnects are feasible in the near term and optical is the only transmission medium that can stay ahead of the accelerating global demand for broadband, the company said.
This will enable the miniaturisation of new optochips which, in turn, will help develop a whole new class of devices and applications."
