This document discusses ultra-flexible modulation techniques that can increase network capacity by up to 30 times. It describes how ADVA Optical Networking's FSP 3000 TeraFlex capabilities provide dramatically boosted network capacity through flexible modulation formats. Key applications discussed include maximizing capacity in existing networks, adapting to different network infrastructures, and optimizing bandwidth usage.

Submarine network application
Maximizing reach times capacity in every network
• Open cable – many submarine networks are already disaggregated
• Capacity is the key factor – optimizing channel bandwidth vs. spacing
• Ultra-flexible interfaces enable maximum capacity
• Submarine trial examples (see related press releases):
• Open cable trial: 300Gbit/s via 6800km submarine network at 75GHz spacing
• MAREA cable: 400Gbit/s wavelengths via >6000km, at 75 and 80GHz
