The Pacific's Highest Capacity Subsea Cable Ever Is RFS: Meet Juno

Juno is the Queen of the Olympian gods in Roman Mythology. This 20 fibre pair cable has design capacity of 320 Tbps, which makes it the highest capacity subsea network to connect the US to Asia. It lands at Grover Beach, California, and also has Japanese landings at Shima and Minami-Boso. NTT is the project's main backer and owner. The carrier clearly felt that two Japanese branches along with three cable landing stations (Softbank Maruyama, NTT Shima, and NTT Minami-Boso) would significantly improve resiliency given Japan's reputation for earthquakes and other natural disasters such as tsunamis. As is usual for a NTT project, it created a standalone company known as SerenJuno in which it has majority ownership to minimize risk. This way any misfortunes would not result in the parent company having financial liabilities. NTT is also extremely reserved about revealing capacity owners on the system. I have learned that PCCW is on the system. Details Ownership: NTT and Mitsui. Cap...

META's 1 Petabit Cable And The Evolution Of Spatial Division Multiplexing

In a recent interview META subsea engineers suggested their next project would be a 1 Petabit Trans-Atlantic cable. They pointed to three possible ways of accomplishing it: multicore fibre, use of the C and L spectrum bands, and 50 fibre pair SDM. Pros and Cons 1. Multicore is subject to cross talk. Right now the only multicore cable is the Taiwan-Phillipines-US cable scheduled to go live this year. A Google project with NEC as the vendor, it has two cores per fibre strand and 26 Tbps total per fibre strand or 13 Tbps per core. The challenge is cross talk. The light spills from one core to the other and vice versa. Obviously this distorts the signals and at high transmission rates the distortions become greater and greater and the signal-to-noise ratio disintegrates. The advantage of multicore fibre is that no redesigning of the optical amplifiers is required. Since everyone acknowledges that SDM alone is unlikely to surpass the half terabit mark, Google is obviously interested in mult...

SubOptic 2025 Conference - Anjana Cable Details Revealed

Anjana is a half terabit META cable landing at Myrtle Beach, South Carolina, and Santander, Spain. It is well known that the design capacity is 480 Tbps based on 24 fibre pairs. Here are some new details: A. There are 89 optical amplifiers space 80 kilometers apart. That's 48 US miles and is near the amplifier distance limit for high capacity systems. B. The presenter said it uses 8,000 volts of DC. I ask the engineers reading this post to tell me if this makes sense. C. The standard for a reliable subsea network is one bad bit in a trillion or less. In other words, a bit error equal or less than 10 to the minus 12 power.
