that became operational in 2001. It had an original design capacity of 640 Gbit/s, but was initially equipped to use only 80 Gbit/s of this capacity. In April 2008 a capacity upgrade was completed, bringing equipped capacity to 240 Gbit/s. Design capacity was also increased to 1000 Gbit/s. Further upgrades will increase equipped capacity to meet increasing demand.
International Cable Protection Committee. The AJC network employs a collapsed loop design that features diverse landings in Australia, Guam and Japan and diverse routing at water depths less than 4000m. This design reduces cost by using a common sheath in deep water, where risk of failure is low, but provides redundancy to mitigate risk in shallower waters and in the landing stations. The network supports a range of access interfaces, including SDH at STM1, STM4, STM16 and STM64 levels, 2.5G clear, Direct Wavelength Access,
