JASURAUS (cable system)
Encyclopedia
Jasuraus is a 5 Gbit/s, 2800km optical submarine telecommunications cable
connecting Jakarta
in Indonesia
to Port Hedland In Australia
. The name was derived from a concatenation of the original planned sites of 'Jakarta' - 'Surabaya' - 'Australia'. However the Surabaya landing was abandoned before project commencement, though the name remained.
Originally conceived as a link from Australia to provide telephony services connection to the world in 1995-1996 its capacity and major role was overtaken in 2000 by the 40 Gbit/s SeaMeWe3
and 320 Gbit/s Southern Cross Cable Network
. It remains to this day as an emergency backup link out of Australia, as well as handling some minimal capacity for organisations such as The Australian Academic and Research Network AARNet
as part of its connectivity to the APCN Cable System
.
At time of being ready for service in 1997, the main cables linking Australia to the world were Tasman2 (Sydney
to Auckland
connecting with Pac Rim East continuing to Hawaii
) 2 fibre pairs of 560 Mbit/s and Pac Rim West
(Sydney
to Guam
) 2 fibre pairs of 560 Mbit/s and was a dramatic increase in network capacity.
Cost factors have proven an issue for the primary operators Telstra
and Optus
often with cables and technology in general, they reach the end of their economic life, well ahead of their operational life which is generally around twenty years, Jasaurus has an expected life of 25 years.
At the beginning of the Internet Era capacity requirements grew rapidly. The upgrade ability was also hampered by the high cost which Telstra
charged to provide transit to Perth
, and whilst the cable could have been potentially upgraded to 20 Gbit/s, such agreements would have to have agreement between all parties and especially APCN's
owners. Such agreements were not forthcoming.
