Q&A Session 2 – Andrey Golovanov
summary
Aluminum subsea cable math: aluminum is 61% as conductive as copper, 30% of the weight and 25% of the price, so cables use more aluminum to match resistivity and end up ~50% lighter and ~60% cheaper while cutting ohmic losses that today consume ~50% of subsea power. Typical project timelines run 4–6 years due to seabed surveys and permits; unmanned survey boats like Saildrone are being trialed. Operations use CLI, TL1 and netconf; migrations mean coordinated capacity moves across endpoints with synchronized scheduling. Control plane resilience uses geo blast‑shield partitioning, per‑geo controllers and dual‑vendor roles often running Sonic.
