Fujitsu and HHI achieve optical amplitude noise reduction using ultra high-speed optical switch
( 01 Jun 2008 )
Fujitsu Laboratories and Fraunhofer Institute for Telecommunications, Heinrich Hertz Institut (HHI) have developed an ultra high-speed optical switch that uses nonlinear optical fiber to reduce optical amplitude noise,which degrades the quality of optical signals when they are transmitted. Employing this technology, suppression of optical amplitude noise using a 107Gbps phase modulated ultra high-speed signal was successfully verified. In addition, in a data transmission test across 320km, it was verified that data quality after transmission could be received with roughly the equivalent of its quality prior to transmission.
Both companies anticipate that this new technology will be applied to optical regeneration, which is a key technology for next-generation ultra high-speed photonic networks.
