Subsea Cables & Internet Infrastructure

Fastnet is a 16 fibre pair submarine network landing in Maryland and in Southern Ireland near Castlefreke. Design capacity is 320 Tbps. This is the first cable in perhaps ten years to land in Ireland and the first landing ever in Maryland. The Irish landing makes perfect sense; Amazon has roughly 350,000 m2 of data center space in the country. It hosts an important cloud region (eu-west-1) there in large part due to a very low corporate tax rate. In addition, it just received clearance to build three data centers near Dublin totaling usable space of 42,585 m2. The choice of Maryland again shows that the hyperscalers value resiliency versus latency more than do the wholesale carriers and telecom incumbents. The latter focus on low latency routes for both Internet backbone and financial trading firms. The main US East Coast telecom hubs are Secaucus Equinix and Ashburn Equinix. If latency was Amazon's top priority, Maryland would not have been the landing point. The sa...

Bevan Slattery likes to build things. His latest project, scheduled for a 2028 RFS, is the16 fibre pair APX-EAST cable linking Australia to the US. Bevan is Subco's CEO, one of the few successful private cable sea builders and operators. Previous projects include the OMAN to Australia system. The US Pentagon was the anchor tenant on that cable. Subco is a consortium member of the relatively low capacity, but important Indigo West cable linking Singapore to Perth and Sydney.  APX-EAST is designed to be fully powered by either end point. This is a resilience feature that should appeal to hyperscalers looking to take capacity on the system. I believe Google's Firmina also can be fully powered from either end point as well. Might not be a coincidence.  But the most striking feature is the lack of optical regeneration. Let's be clear. This cable is repeatered. It will use optical amplifiers like all other repeatered systems. Optical regeneration in this context means landing the...
