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.
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 utilising 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, Gigabit Ethernet
Gigabit Ethernet
Gigabit Ethernet is a term describing various technologies for transmitting Ethernet frames at a rate of a gigabit per second , as defined by the IEEE 802.3-2008 standard. It came into use beginning in 1999, gradually supplanting Fast Ethernet in wired local networks where it performed...
and 10 Gigabit Ethernet
10 Gigabit Ethernet
The 10 gigabit Ethernet computer networking standard was first published in 2002. It defines a version of Ethernet with a nominal data rate of 10 Gbit/s , ten times faster than gigabit Ethernet.10 gigabit Ethernet defines only full duplex point to point links which are generally connected by...
. A range of protection options are available, including SDH span and ring protection and 1:n wavelength redundancy.
The cable has a design life to 2026.
Landing pointsCable landing pointA cable landing point is the location where a submarine or other underwater cable makes landfall. The term is most often used for the landfall points of submarine telecommunications cables and submarine power cables. The landing will either be direct or via a branch from a main cable using a...
