5.7 Tbps Throughput FSO Link At The University of Eindhoven

University of Eindhoven in the Netherlands has set up a 4.6 kilometer free space optical link that traverses the city center. Its throughput is 5.7 Tbps. Unfortunately, I don't see signal to noise measurements. Free space lasers suffer from atmospheric turbulence such as rain, fog, and clouds. They work well in outer space. The technology is the basis of the new NASA deep space communications network.

Breaking Story: Facebook Building Subsea Cable That Will Encompass The World

Image
Several sources have whispered in my ear that META is planning a new 16 fibre pair cable that will encompass the world going from the US East Coast to the US West Coast via the Atlantic, Indian Ocean, and the Pacific. The most ambitious subsea project ever undertaken. I do not know the exact routing. I know that the cable will launch from the American East Coast and will go down the West African Coast to South Africa and then head straight to Mumbai. It is not clear if Europe will be online or not. From Mumbai it will head straight to Australia and then up to the US West Coast. I speculate that there may be branching units to Singapore, Malaysia, and Indonesia. But the basic routing is US/South Africa/India/Australia/US. What is not clear is if there will be branching units to add more countries to the cable.  This semi-secret cable reflects META's desire for network resiliency given the four month Red Sea down time that AAE-1 and other subsea cables suffered during the first half ...

Facebook's Semi-Secret W Cable

Image
 A few days ago I wrote that Facebook was planning a new subsea cable directly linking the US East Coast to South Africa, then up to India, onward to Australia, and finally to the US West Coast. Clearly resiliency is a big theme. It avoids Lisbon, Marseille, Egypt, the Red Sea, and Singapore. All choke points due to their telecom hub status. Note that the map below shows lots of branching units, but I don't have insider confirmation although they make perfect sense. The cable is 16 fibre pairs.  This cable may be heavily influenced by AI considerations. AI data centres require lots of space and power. The US, South Africa, India, and Australia are good candidates for AI data centres in terms of space. All of them except for South Africa have modern power grids. But South Africa is still the best place on the continent for large scale AI facilities. An AI theme makes particular sense given the cable's high latency. An AI data centre does not directly serve custo...

How To Calculate An IRU Price For a 100G Wavelength

The IRU price should reflect your forecast of future lease revenes. If the current MRC is high and prices have been stable and are expected to remain so, then the opportunity cost of selling an IRU is high. You are sacrificing a lot of lease revenue if you sell that capacity. In this case the upfront IRU price should equal the three year MRC multipled by 4 to 6 years. So if the three year Faster cable MRC is $17K, then 48x to 72x times that number is fair value. So 48*$17K=$816K. Plus a standard 4% annual fee to cover the wavelength's share of maintenance and operations.. So strong markets and tight capacity mean that leasing is more attractive than IRUs to the supplier. Vice versa, the buyers will be desperate to lower their long term costs via an IRU. In my example, $816K divided by 15 years equates to $4500 per month excluding O&M. Bad for the seller. Good for the buyer. That's why so many of you are looking for IRU capacity to resell to your clients, but finding few se...
