Space-based optical communications becomes a $12.9B strategic market

The third edition of Novaspace’s Optical Communications Market report forecasts cumulative global revenues for space-based Laser Communication Terminals (LCTs) to reach $12.9 billion through 2035, driven overwhelmingly by LEO constellations, which will account for more than 99% of demand.

“As constellations scale and operators seek to reduce reliance on extensive ground infrastructure, optical communications provide the high-capacity, efficient data transfer needed to maintain seamless connectivity,” said Rami Ibrahim.

LCTs are rapidly transitioning from emerging technology to a core component of next-generation satellite networks. The total number of terminals in orbit is projected to reach 118,000 units by 2035. Closed markets – where LCTs are developed in-house – are expected to represent 74% of total market value (2026–2035), with open markets accounting for the remaining 26%.

Growth in space-based optical links is being matched by expansion on the ground. The number of Optical Ground Segment (OGS) assets is projected to grow at a 31.3% CAGR, surpassing 830 units by 2035, with cumulative OGS revenues reaching $774 million over the same period.

The continued expansion of NGSO constellations and data-intensive applications, particularly in Earth observation, is accelerating deployment. Large-scale satellite operators and mega-constellations are expected to be the primary drivers of OGS market growth and scaling.

“As optical links move from niche deployments to a core capability, execution will be critical,” added Ibrahim. “Adopting optical communications is becoming essential to future-proof satellite networks and position operators for sustained value creation in an increasingly data-driven market.”
