The British Empire's Resilient Subsea Telegraph Network

Image
The British empire had largely completed its Red Line cable network by 1902. This network allowed news and messages to be delivered in a few minutes or several hours at most depending on the message queue's length. It spanned the globe and formed a network ring so traffic could be routed in the opposite direction in case of disruption. It was, as Dr. Michael Delaunay has argued, a highly resilient network. Besides the ring configuration, the network relied on multiple cables between any pair of given end points to ensure uptime. The British military believed it would be impossible for an enemy to cut enough cables on any route to sever all communications between any given pair of end points. The Committee of Imperial Defense concluded that 57 cables must be shut down to isolate the British Isles from the Red Line network. The figure was 15 for Canada and 7 for South Africa. The Empire was self sufficient in terms of manufacturing the components for a subsea telegraph cable and re...

The Short Life Expectancy of Starlink's LEO Satellites

Image
According to FCC filings Starlink shut down almost 500 Starlink satellites during the first half of 2025. The company had them reenter the atmosphere where they burned up. What is striking is that these satellites were all less than 5 years old. The general consensus is that LEOs have a life expectancy ranging from 5 to 8 years. Shorter than expected life spans for the satellites will hit Starlink's income statement hard by increasing network depreciation and replacement needs. However, Starlink has managed to lower its LEO's manufacturing costs down to $500K versus initial figures around $1 million. So these production economies of scale might offset some of the higher than expected depreciation. However, there are also rocket launch costs as well. It costs Starlink about $3 million to put a satellite into orbit. The Falcon 9 costs $67 million per flight and delivers 23 LEOs into low Earth orbit. As a private company Starlink financials are a bit of mystery. The company press ...

Update on META's Waterworth Project

Image
META has started selecting landing sites. As the map below shows, the subsea cable's routing is unique, a record breaking 50,000 kilometers in length, and it will form a ring around the world. A ring allows Facebook to reroute traffic in the opposite direction if there is a fault. Waterworth is a 24 fibre pair system. That puts at the top of the fiber pair count for spatial division multiplexing systems. So figure a design transmission rate of a half petabit per second.  Although crazy news outlets have reported it will cost $10 billion, that figure is absurd. The project can easily be done for $2 billion or less even with extensive terrestrial trenching to create new and unique fibre routes. Will the project use new technologies like multicore fibre or multiband spectrum? Doubtful. The price tag dictates the META subsea cable design team will use standard proven technology. No one wants to tell their boss they just wasted $1.5 billion dollars. It is not good for your career. 😃 Wa...
