Research of data transmission system of IBM light emitting rate up to 25Gbps per channel

IBM announced a few days ago, the company developed a using light instead of electronic signal for the data transmission mode, this technology may soon make large file transfer limit into history.

IBM says, this ” groundbreaking ” technology in the calculation of light pulse to replace the electronic signal – named the ” Silicon nanophotonics ” – available in a single piece by the 100nm semiconductor technology made of silicon chip to create a different optical components and circuit collaborative environment.

Nano silicon photonics is designed to let the server, large data center and super computer computer chips in large data transfer speed. The pulses of light rather than electronic signals are used, the research field behind the concept is to slow down the computer relay point between the congestion, and reduce the traditional mode of interconnection fee.

The transmission system transceiver can reach 25Gbps each channel data transmission rate. In addition, the technique is also able to cope with a plurality of parallel optical data stream, and the use of a compact chip internal wave division multiplexing equipment they twist into a single strand of fiber. This at a high rate multiplexer to transfer large amounts of data flow concept is expected soon to commercial application.
