Infinera details resolution of AJC submarine cable network outage

Infinera (NASDAQ:INFN) asserts its Time-based Instant Bandwidth technology helped Australia Japan Cable (AJC) recover from a recent network outage. The outage resulted from a network path failure following a submarine cable network fault at a depth of 7,000 to 8,000 m.

The 12,700-km AJC undersea cable network connects Australia, Guam, and Japan (see "Australia Japan Cable nearing completion after reaching Australian shores"). The network suffered a subsea fault along the route between Maruyama, Japan and Tumon Bay, Guam. Thanks to the fiber-optic network's ring configuration, Infinera and AJC technicians were able to reroute more than 400 Gbps of traffic from the faulty section to alternative paths using the Time-based Instant Bandwidth technology within the DTN-X platforms AJC uses on parts of the network (see "Australia Japan Cable submarine network adds Infinera DTN-X"). The alternative routes included one terrestrial and two subsea AJC segments.

As its name implies, the Time-based Instant Bandwidth capability enables on-demand activation of bandwidth for bounded periods of time, with the deactivation of the line-side bandwidth at the end of the specified period. It is a variation on Infinera's Instant Bandwidth capability, which is designed to permanently add increments of bandwidth as capacity needs increase (see "Infinera offers Instant Bandwidth on DTN-X packet optical transport platform").

The fault was later repaired, Infinera says.
