In a large data center like Facebook and Google, there are many high-speed servers that are processing as well as exchanging much data at extremely high speeds. It was reported according to Facebook’s Dunn Lee that the peak pipe speed required for Facebook data center server communications have reached 4 terabits/second. Currently the company is [...]
With the 100G Ethernet commercially available, now people are aiming at the next generation Ethernet technology. In OFC/NFOEC 2008, people considered one terabit Ethernet. After that, some initial investigations were booming in academy. For example, some researchers are using optical coherent-OFDM technology to carry one terabit per second data rate over a single channel over [...]
Orthogonal frequency division multiplexing (OFDM), which was original developed for wireless communication technique for efficient spectrum utilization, has been successfully extended to optical transmission systems. One of key advantages is the OFDM-based technology has better tolerance to fiber dispersion and is expected to support high data-rate over a single channel through modulating multiple low-rate data [...]
In this year’s OFC/NFOEC there is a special panel session on Terabit Ethernet organized by Andrew Ellis, Seb Savory respectively from Tyndall Natl. Inst., Ireland, and Univ. College London, UK. Viewing the fact of increasing bandwidth requirement and the success of 100G Ethernet commercial deployment, people are more and more interested in the next generation [...]
We have seen 100G Ethernet commercially available in year 2009. In year 2008, people were talking about Terabit Ethernet on OFC/NFOEC. It was predicted that the technology would be commercially deployed in year 2015, according to the father of Ethernet, Bob Metcalfe. Please the interesting video show below from lightreading.com
