Southern Cross Cable Limited (“Southern Cross”) and Ciena announced recently to deploy GeoMesh Extreme submarine solution utilising Ciena’s 6500 Submarine Line Terminating Equipment (“SLTE”) powered by WaveLogic 5 Extreme coherent optics for the new 13,494 km Southern Cross NEXT (“NEXT”) submarine cable in the Pacific.

This deployment will allow Southern Cross to not only tackle the growing demand for bandwidth but also support the resiliency, reconfigurability, and rapid activation requirements that their customers have become accustomed to from Southern Cross, as end-user digital applications continue to proliferate and require global networks to become more adaptive,

The Southern Cross NEXT system will leverage Ciena’s WaveLogic 5 Extreme to seamlessly mesh the new system into the current Southern Cross network fabric while supporting higher connectivity services and a fully integrated eco-system. Consisting of three diverse submarine cable routes, 20+ access points, and over 43,000km, this single ecosystem supports high capacity and low latency routes between Australia, New Zealand, Fiji, Tokelau, Kiribati, Hawaii, and the US West Coast.

According to Southern Cross Cables Limited,  Southern Cross engaged an external global consultancy to independently review and evaluate the various leading industry solutions and after a thorough process, the Ciena WaveLogic 5 Extreme was identified as the ideal choice.

To be completed in early 2022, the Southern Cross NEXT cable will leverage the Ciena GeoMesh Extreme submarine solution as part of the overall Southern Cross network fabric to seamlessly integrate the multiple terabits of traffic across the network; Manage, Control and Plan (MCP) for network planning and operational management of services; Blue Planet Bandwidth on Demand (BoD) to support and enhance service flexibility; and the Insights Service to optimize network analysis, all at lowering power requirements per bit in support of Southern Cross’ sustainability goals.
