Subsea Cables & Internet Infrastructure

This project will deploy the first fibre optic cable to connect connect Ireland to Continental Europe. Pisces provides a unique route that sharply improves the resiliency of Ireland's connectivity to the rest of the world. The EU loves projects that bypass non-EU countries and directly ties together EU member states. As the UK is notorious for surveillance, it is particularly welcomed. Consortium members include the Irish subsea permitting firm, MDM, an equity fund appropriately named Equitix, and Orange. The cable will have 16 fiber pairs. I estimate aggregate throughput will be at least 320 Tbps. I admire the unique routing of this system. What is not clear to me is the hyperscaler demand for its capacity. Microsoft has agreed at least in principle to take a fibre pair. There is certainly a prima facie case for Google and Amazon to take single fibre pair IRUs on the system because it will improve their own network's resiliency. However, that advantage must be balanced against...

Americans like to focus on the first short lived Trans-Atlantic cable, a project completed in 1858. But the first commercial and successful subsea communication cable connected Paris and London. The honors go to the startup English Channel Submarine Cable Company, which two engineer brothers, Jacob and John Watkins Brett, founded. Its first attempt in 1850 failed. There are several differing accounts. What these accounts have in common is that the cable had no protection. One colorful story is that the cable lasted 24 hours before a French fisherman cut the cable thinking it was a new type of seaweed. According to this account, the cable sent a telegraph message to Prince Louis Napoleon Bonaparte before the cable died. Other more reliable accounts suggest the cable never worked at all. But the second attempt in 1851 using armored cable was successful. Commercial telegraph service between London and Paris began November13, 1851. Landing points were near Calais and Dover. It was viewed a...
