Vitesse Semiconductor Corp. says it has shipped more than five million of its VSC7716 burst-mode transimpedance amplifiers (TIAs) for EPON in FTTx applications. Infonetics Research estimates that approximately 5.7 million EPON optical line termination (OLT) ports will be shipped by 2012; therefore, the milestone is proof of Vitesse's market leadership position in burst-mode EPON TIAs, the company asserts.

Fujitsu Ltd. has detailed research that could make digital signal processing (DSP) chips for coherent detection significantly smaller, lower cost, and less power hungry. The new chip design can compensate not only for linear distortions of the optical signal like chromatic dispersion, but also for complex waveform distortion caused by nonlinear effects – something that the current generation of DSP chips does not do.

Fastweb, one of Italy‘s largest broadband providers, is deploying the country’s first 100 Gigabit per second (100G) per channel optical fiber network between Milan and Rome. Using Nokia Siemens Networks technology, the network will be capable of simultaneously transmitting up to 40 wavelengths of light, each carrying data at 100G. This will allow a total data transfer speed of up to 4 Terabits per second.
