- Utilises Ciena’s WaveLogic 6 Extreme on NO-UK system between Norway and UK
What happened: Record-setting subsea transmission reaches 1.6 Tb/s over in-service cable
Altibox Carrier has demonstrated the world’s first 1.6 terabits-per-second single-carrier wavelength over an active submarine fibre cable using Ciena’s WaveLogic 6 Extreme (WL6e). The trial ran error-free on Altibox’s NO-UK system connecting Norway and the UK, achieving a spectral efficiency greater than 9 b/s/Hz. This live, high-capacity trial proves that terabit-scale transmission is now achievable in real-world subsea networks.
