Japanese Break Bandwidth Record: 450 Tbps On A Single Standard Fibre Pair

Image
The National Institute of IT and Communication Technology (NICT) in Japan has been diligently working for many years on dramatically increasing fibre optic bandwidth by using a wider spectrum range than the traditional C and L bands. The long haul fibre optic networks have relied exclusively on the C and L bands because they offer the lowest optical attenuation for silicon-based fibre optics. Light in these frequency bands fades and loses strength relatively slowly as it passes through fibre optic glass. But as the chart below shows, the C and L bands comprise just a fraction of the available spectrum that lasers can use.  In this trial the NICT achieved 450 Tbps on a repeatered London metro fibre pair connecting Telehouse London to the University of London. Because existing optical amplifiers are designed to work only in the C and L bands, NICT has spent years developing amplifiers optimized for the O, E, S, and U bands. These bands required that the fibre optic strands in the am...

The Anthropic xAI Deal Is An Admission Of Failure

Image
The chart shows US business paid AI subscription growth. Musk's AI company is in last place. He shoved xAI into SpaceX in order to siphon off SpaceX cash flow and IPO proceeds to finance his struggling venture. On its own, no one would lend to xAI given its third tier position in the AI service and its $1 billion per month cash burn. Now Anthropic is leasing a huge chunk of xAI data center capacity to estimate its models. Supposedly worth about $1.25 billion per month. I say supposedly because contracts can vary from rock solid to as soft as jello. Indeed, some industry contracts are really just letters of intent, non-binding expressions of customer interest. In this case both sides can cancel the agreement with only 90 days notice. Again, the Musk cheerleaders are prematurely celebrating. What this deal implies is that there's very little demand for xAI's models. So just as X pivoted from social media platform to AI, it is now pivoting to the AI data center b...

More Details On The 2Africa Cable Design & Capacity

Image
The standard description is that 2Africa is a 16 fibre pair cable with 180 Tbps throughput. It comes right off the 2Africa website. That public figure is a bit misleading. Only the Mediterranean and Red Sea segments have 16 pairs. The all-important West Coast segment has 8. Now these fibre pairs should individually be capable of 20 Tbps or slightly more. So West Coast transmission capacity probably does total 180 Tbps. Indeed, the Mediterranean segment could easily exceed 320 Tbps. And the same for the yet unfinished Red Sea segment. Design Capacity By Segment A. Mediterranean Sea: 16. B. Red Sea: 16. Not finished due to hostilities. C. Red/East Africa: 7. D. Red Sea/India: 9. E. West Coast: 8.

Starlink IPO Prospectus Insights: Huge Negative Cash Flow

Image
The chart below shows the issue. Total 2025 investments totaled $19.5 billion, yet the 1Q2026 investment alone was $16 billion. So unless the first quarter is an outlier, we are looking at $80 billion spent this year with most of it on an AI business that grew 22% in 2025 versus openAI's 230%. Note that xAI's recent deal with Anthropic does not necessarily improve the situation. This contract involves using xAI's data centers to train Anthropic large language models. Contracts of this nature are often closer to letters of intent than hard revenue commitments. And while such a deal might generate a lot more revenue, it will probably also require Starlink to spend more money on power, buy more GPUs, and the like. In other words, this deal might increase the company's negative cash flows. Starlink's current debt at the end of the first quarter of 2026 was $26 billion. The IPO will provide ample cash to wipe the slate clean, but there is a clear risk given that Musk is ...

AI Division Severely Harming SpaceX Financial Results

Image
1. AI division booked a $2.5 billion loss in operating income in the first quarter of 2026. The AI division began as X, but when Musk got AI religion, he pivoted towards developing the Grok large language model and two large AI data centers. To a large extent, he was searching for a way to make X profitable as the site right wing toxicity caused the loss of billions of dollars in advertising revenue. 2. The AI division is causing SpaceX as a whole to suffer massive bottom line losses. It is offsetting the healthy net income of the Internet service division. 3. Transforming X into an AI company with a large language model and accompanying GPU infrastructure was both a me-too investor move and an act of financial desperation. Musk's acquisition of X led to advertising revenue declining from $4.7 billion in 2022 to $1.8 billion in 2025. It was easy for Musk to take X private because the widening losses reduces the company's equity value. 4. Musk used his voting sh...

Starlink Consistently Loses Billions - IPO Prospectus Revelations

Image
As the chart shows, Starlink is on track to lose $20 billion this year. These losses largely reflect the struggling xAI division that Musk shotgun merged with Starlink: "SpaceX had a net loss of $4.28 billion on revenue of $4.69 billion for the first quarter, compared with a net loss of $528 million on revenue of about $4 billion a year earlier, the filing shows." Not only does the company lack a clear path to profitability given the xAI division, it is giving Musk permanent control through a special class of voting shares. This is poor corporate governance and should never be done. No man is infallible. It is a recipe for financial disaster as Musk's plans are completely unrealistic and unprofitable like a lunar base, a million orbital data centers, and a Mars colony.
