The
Australia–Japan Cable, or
AJC, is a 12,700 km
submarine telecommunications cable system linking
Australia and
Japan via
Guam that became operational in 2001. It had an original design capacity of 640 Gbit/s, but was initially equipped to utilise 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.
