Vodafone Spain Trials 400G With Alcatel-Lucent

PARIS -- Alcatel-Lucent (Euronext Paris and NYSE: ALU) and Vodafone Spain have successfully carried out a trial of transporting data at speeds of up to 400G (gigabits-per second) over a distance of 400 kilometers between Madrid and Zaragoza using existing optical infrastructure.

The trial was conducted with Alcatel-Lucent’s 400G technology and demonstrates the ability of an existing optical network to carry data at up to 17.6 terabits-per-second (Tbps), doubling the current spectral efficiency in fiber. It is the equivalent of transmitting the contents of 88 Blu-ray discs in a single second while reducing power and space consumption by half.

Key Facts:

  • Successful 400 Gbps transmission trial was conducted on Vodafone Spain’s existing Dispersion Compensation Module network between Madrid and Zaragoza.
  • Trial covered a distance of 400km using the existing optical network that was originally carrying a mix of 10 Gbps, 40 Gbps & 100 Gbps traffic streams.
  • Alcatel-Lucent’s optical trial solution is based on its 1830 Photonic Service Switch platform, and has the ability to be deployed simultaneously with existing multiple 10 Gbps, 40 Gbps and 100 Gbps network links.
  • 400 Gbps optical technology was developed by Bell Labs, Alcatel-Lucent’s research arm, to address the capacity requirements that networks are experiencing with the emergence of new applications, services and smart devices that require high bandwidth and seamless connectivity.
  • Trial demonstrated that 400 Gbps transmission can be added on an existing network without disruption of the traffic or reengineering of the optical link.

    Type of modulation? Is there a reason they don't say what type of modulation is used?  That would seem to be the critical piece of information regarding this trial.
