Spark begins deployment of faster, ‘self-healing’ optical transport network

21 Jul 2020

New Zealand telco Spark has announced the completion of the first stage of its next generation optical transport network (OTN 2) with ‘self-healing’ capabilities to automatically restore services after events such as natural disasters. The rollout will also increase data capacity on Spark’s network by up to eight times and support the company’s 5G services. The first section of the new OTN 2 fibre network has been installed between Glenfield and Papakura in Auckland, and is now live and operating at 800Gbps.

Spark selected Ciena to supply the hardware, software and services to design and build its OTN 2, including solutions to enable a more efficient and resilient network that can adapt to customer needs and quickly respond to potential network faults by re-routing traffic as needed based on available network resources.

The OTN 2 rollout is a two-year project which has started in Auckland and will expand towards Hamilton, Wellington and Christchurch. Initially the new OTN equipment will be an express overlay to the existing core network, but will then eventually replace the existing network.
