Agile DSP-based Optical Transmission Systems

OPN7.pngWith exponential traffic growth projected from mobile and cloud applications, optical networks powering the Internet backbone will require orders-of-magnitude transmission capacity gains. At the core of our innovation in this area are agile digital signal processing (DSP)-based approaches, including digital Nyquist spectral shaping, DSP-based nonlinearity compensation, and advanced soft-decision forward error correction (FEC) that optimize spectrum utilization, maximize transmission reach, and provide data rate flexibility. Our recent world-leading achievements in this area include the first real-time transmission of a 1Tb/s Nyquist superchannel over 7,200km using only erbium doped fiber amplifier (EDFA) repeaters, proving that an ultra high-speed 1Tb/s optical superchannel can have transoceanic reach.

 

Our series of ground-breaking world- and industry- firsts have been showcased in the following press releases:
