Spark completes Cook Strait inter-island cable link

By

New Zealand’s largest telco Spark has completed an upgrade to the Nelson-Levin inter-island cable link across the Cook Strait which it says provides improved resiliency.

The Nelson-to-Levin link is one of New Zealand’s three marine cables carrying data traffic between the North and South Islands; two of the cables are part of Spark’s Network.

The link between Levin and Nelson, installed by Spark in 2001, is 237 km and includes a 212 km submarine section from Nelson’s Cable Bay to Hokio Beach in Levin – and Cable Bay was the landing site of New Zealand’s very first international telegraph cable to Sydney, built in 1876.

Spark general manager Technology Infrastructure Campbell Fraser says the upgrade involved installing the latest optical transport technology at the landing point in Nelson’s Cable Bay and means that traffic can now be re-routed to the cable in the event that one or both of the other inter-island cables fail – securing critical connectivity between the two islands.

According to Fraser, the upgrade offers connectivity benefits to New Zealand.

“The completion of this upgrade improves the resiliency of our network particularly between the North and South Islands, as the Nelson-to-Levin cable is shallow buried rather than laid on the surface of the sea floor, and is away from known fault lines. In emergency situations it gives us more options for routing traffic and keeping people connected.”

Now’s the Time for 400G Migration

The optical fibre community is anxiously awaiting the benefits that 400G capacity per wavelength will bring to existing and future fibre optic networks.

Nearly every business wants to leverage the latest in digital offerings to remain competitive in their respective markets and to provide support for fast and ever-increasing demands for data capacity. 400G is the answer.

Initial challenges are associated with supporting such project and upgrades to fulfil the promise of higher-capacity transport.

The foundation of optical networking infrastructure includes coherent optical transceivers and digital signal processing (DSP), mux/demux, ROADM, and optical amplifiers, all of which must be able to support 400G capacity.

With today’s proprietary power-hungry and high cost transceivers and DSP, how is migration to 400G networks going to be a viable option?

PacketLight's next-generation standardised solutions may be the answer. Click below to read the full article.
