Lightera to Triple Submarine Fiber Capacity by 2029

Executive Signal Summary

Lightera, a global optical fiber and connectivity solutions provider and part of the Furukawa Electric Group, has announced a major capital investment to expand its submarine optical fiber manufacturing operations in Denmark and the United States. The expansion aims to nearly triple manufacturing capacity by 2029 to meet the growing global demand for submarine communications infrastructure, driven by AI infrastructure investments, hyperscale data centers, cloud computing, and network expansion. The company also positions itself for the commercialization of multicore fiber (MCF), with initial submarine deployments expected around 2029-2030. Lightera's facilities in Brøndby, Denmark, and Norcross, Georgia, USA, serve as its global manufacturing centers for submarine optical fiber.

EON: Laser-based Space Links to Replace Subsea Cables

The article argues that subsea fiber — which carries roughly 95% of intercontinental data — is increasingly fragile and slow to expand, citing recent cable cuts and logistical limits of cable-laying. Endeavor Optical Networks (EON) proposes a space-based alternative: ground-to-satellite optical laser relays into Medium Earth Orbit (MEO) using a bent-pipe architecture to deliver multiple terabits per second between continents. The piece describes how cheaper commercial spacecraft, standardized components, and established supply chains now make high-throughput space links economically viable. EON targets hyperscalers, enterprises, and sovereigns, claiming capacity can be deployed in months and providing route-diverse intercontinental bandwidth that avoids the seabed.

Lightcurve Partners with Harmonic for Multi-Gigabit Broadband over Coax

Harmonic announced that broadband service provider Lightcurve is deploying its cOS virtualized broadband platform to deliver multi-gigabit internet speeds to Multi-Dwelling Units (MDUs) in central and western Washington state. Using Harmonic's Oyster nodes with Pebble Remote PHY devices in a distributed access architecture, Lightcurve can offer up to 8 Gbps downstream and 1 Gbps upstream over existing coaxial wiring, avoiding the cost and disruption of fiber overbuild. The solution also includes Harmonic's Central AI-powered network intelligence for proactive troubleshooting. Lightcurve's COO, Dr. Pao Lo, emphasized the speed and cost-effectiveness of the deployment, while Harmonic's SVP of Global Sales, Jeffrey Glahn, highlighted the capital-efficient path to multi-gigabit broadband. Harmonic will showcase the platform at SCTE TechExpo26.

Ex-SpaceX Engineers Raise $50M to Revolutionize Data Centers

Three former SpaceX engineers — Travis Brashears, Cameron Robinson and Serena Grown-Haeberli — founded Mesh Optical Technologies, a Los Angeles startup that raised $50 million in a Series A led by Thrive Capital. Mesh plans to mass-produce optical transceivers for data centers (targeting a production rate of 1,000 units per day within the year) to serve high-performance GPU clusters used for large AI model training and inference. The company aims to build supply chains outside China and qualify for bulk orders in 2027–2028. Mesh’s design removes a power-hungry component that its founders say could cut GPU-cluster power use by 3–5%. Investors frame the company as addressing interconnect bottlenecks and national-security risks tied to reliance on Chinese suppliers.
