IBM Set New Record In Data-Transfer Speeds

Analysts have set a new record for data transfer over multimode optical fibre sending data @ 64 gb per second. Researches at IBM Corporation sent data @ 64 gigabits per sec over a cable 57 metres long using a sort of laser termed as vertical cavity surface emitting laser.

IBM Set New Record In Data-Transfer Speeds

The success rate was about 14% speed than the previous record and that is about 2-5 times speed than the capabilities of current typical commercial technology.Analysts also revealed the success proved that the standard, existing technology for sending data over short distance should be able to meet the improving needs of servers, data centers and supercomputers by the end of this decade. Also said that to improve or suceed such high speed, analyst used the VCSEL lasers advanced at Chalmers University of Technology in Sweden and custom silicon-germanium chips developed at IBM Corporation.

The receiver chip is rare and uncommom design that together accomplish speed and sensitivities well beyond todays commercial offerings. Reseacher Dan Kuchta of IBM TJ Watson research center in NY.The driver chip integrates transmit equalization which widens the bandwidth of the optical link. While this design has been universally used in electcal communication, it hasn’t yet captured in optical communication.

Analysts consistently rely on the rule of thumb that says the usable data transfer rate if about times the bandwidth. With VCSEL laser which has the bandwidth of about 26GHz, the rate would be only about 44 Gb. The quick speed only worked for as distance of 57 metres, means this technology is not designed for sending the data across continents.
