How Infinera assisted AJC to recover network on submarine


Infinera today said it assisted Australia Japan Cable (AJC) to recover network capacity on the submarine optical fiber cable connecting Australia, Guam and Japan.

In order to recover the network, Infinera and AJC rerouted over 400 Gb/s of traffic from the affected AJC section to alternate paths on the AJC optical fiber ring configuration. Earlier, AJC experienced a network path failure following a subsea cable fault in 7,000 meters to 8,000 meters water depth.

The rerouting utilized the Infinera DTN-X platform featuring its new on-demand Time-based Instant Bandwidth technology. The submarine cable company started the rerouting of the lost traffic within minutes after AJC receiving the Time-based Instant Bandwidth license. AJC could avoid a route outage while the cable repair ship was mobilized, transited to the repair site, and implemented in the challenging deep water repair.

AJC experienced a subsea fault affecting services operating on the optical fiber route between Maruyama, Japan and Tumon Bay, Guam, including services on the Infinera DTN-X and other vendor platforms.

AJC utilized Infinera’s new Time-based Instant Bandwidth technology to activate new capacity on an alternate AJC route because of the systems ring-based architecture and recover all of the traffic being carried via Infinera equipment.

An expansion of Infinera’s Instant Bandwidth enables the on demand activation of bandwidth in those increments for specified durations of time, with the deactivation of the line-side bandwidth at the end of the time period.

AJC deployed the Infinera DTN-X platform to deliver up to five terabits per second of non-blocking optical transport network capacity with 500 Gb/s super-channels. The high capacity super-channels are enabled by PICs developed and fabricated by Infinera.
