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...
