Australia Japan Cable Reroutes Around Subsea Cable Fault with Infinera

The Australia Japan Cable recently experienced a network path failure following a subsea cable fault in 7,000 meters to 8,000 meters water depth, but was able to quickly reroute 400 Gbps of traffic to alternate paths.  The fast reroute capability was enabled by capabilities of the Infinera DTN-X platform featuring Infinera’s new on-demand Time-based Instant Bandwidth technology. 

The rerouting of the lost traffic was able to commence within minutes after receipt by AJC of the Time-based Instant Bandwidth license. This avoided a route outage while the cable repair ship was mobilized, transited to the repair site, and implemented in the challenging deep water repair.

AJC is a private submarine cable network and operates a 12,700 km link from Sydney to Tokyo via Guam. 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. Using Infinera’s new Time-based Instant Bandwidth technology, AJC in collaboration with Infinera was able to quickly respond by activating network capacity over an alternate route consisting of one terrestrial and two subsea AJC segments to recover over 400 Gb/s of affected traffic.

“We are pleased to continue our successful partnership with AJC,” said Lonny Orona, executive vice president for customer support at Infinera. “Customer satisfaction is of utmost importance to us and we are committed to help in any way possible so they can, in turn, fully meet their customers’ needs. Both the AJC and Infinera teams worked jointly with urgency to recover network capacity, minimizing disruption to the AJC network and services.”
