Some submarine systems, aged 20–25 years, are approaching end-of-life and require replacement or augmentation. Ultra-high fiber-pair systems (48+, 96 pairs) with open spectral capacity appeal to futures proofing.

CHALLENGE

"Complex multi-stakeholder coordination and geopolitical risk"

Cross-border submarine cable projects often involve multiple nations, each with distinct licensing, law, and marine regulation—coordination is challenging. Cable routes traversing disputed maritime zones face geopolitical tension and potential sabotage. Regulatory discrepancies in marine protection zones, fishing lanes, and territorial waters necessitate lengthy approvals. Data sovereignty & national security policies can restrict foreign participation. Maintenance in remote ocean zones requires vessel availability; globally, only ~ 60 specialized repair vessels are in operation.
