Upgrade Project 2008
AJC CAPACITY UPGRADE
In mid 2007 AJC contracted for an Upgrade of the initially installed AJC capacity of 40G+40G by 80G+80G to total 120G+120G (equivalent to 240G unprotected). This Upgrade required some additional equipment in each of the AJC cable stations but no change to the wet segment comprising the submarine cable and repeaters. The Upgrade was partially completed in December 2007, with final upgrade acceptance as scheduled on 14 April 2008. The Upgrade has a five year warranty.
As part of the analysis for the Upgrade, the supplier advised that technical improvements, including new FEC (Forward Error Correction), provide increased design capacity to a minimum of 1320 Gbit/s between Australia and Guam and 1000 Gbit/s between Guam and Japan. The different design capacity is due to different repeaters south of Guam compared to north of Guam
The Upgrade provides not only continuity of AJC's existing SDH products of Protected and Unprotected capacity but supports higher speed interfaces and introduced GbE & 10GbE Ethernet plus 10G Direct Wavelength Access capacity.
