How we’re bringing ‘continuous connection’ to our subsea cables

We live in a world of continuous connection. As part of my job, I am always on the go. While I’m writing this article from Hong Kong, I’m constantly connected to my home in Singapore. I read the news from my smartphone, collaborate with colleagues via my laptop, and video call my family (the best part of my day).

It’s a constant connection that I know I take for granted. But without it, I simply couldn’t do my job and remain so connected to home. That’s why I’m excited to announce that together with Ericsson and Ciena, Telstra is launching a new rapid restoration service on our busiest subsea cable routes in Asia – to help keep all of us connected.

When we watch Netflix or shop online, often we don’t think about the technology that enables it. All of this connectivity is made possible by intricate fibre-optic cable systems under the sea. In fact, 99 per cent of the world’s international data is transmitted through subsea cables.

But that doesn’t come without its challenges. Telstra is proud to have the largest subsea cable system in the Asia Pacific, and earlier this week we announced two new investments that further grow our diverse footprint.

The Asian region however, presents one of the most challenging environments for subsea cable systems. Busy and shallow shipping ports in Hong Kong and Singapore, high-levels of fishing activity across northern Asia, and an ecosystem prone to natural disasters, all threaten to disrupt or damage underwater infrastructure.

And the reality is, damage to a subsea cable can take weeks or even months to fix. Enter our continuous connection service. By combining the vast scale and diversity of Telstra’s subsea cable network, with flexible programmable infrastructure technology through Ciena’s GeoMesh Extreme solution, we can reroute customers impacted by potential damage to another subsea cable path. What’s more, we can do this in less than 30 minutes.

Following successful trials in December, the new service is now available on Telstra’s Hong Kong to Singapore, Singapore to Japan, and Japan to Hong Kong routes.

Our continuous connection service builds on Telstra’s assured availability “Always on” service, which currently offers restoration within eight hours. Telstra’s new service will reduce that time from hours to minutes – a significant reduction to current restoration service arrangements in Asia.

What Ericsson and Ciena’s technology allows us to do is exciting. By increasing the intelligence of our subsea network, we can rapidly respond to changing network demands – all without manual intervention.

Through the scale and diversity of Telstra’s subsea cable footprint and Ericsson and Ciena’s with flexible programmable infrastructure technology, we are able to help remove the pain of potential network impacts for our customers, with an almost seamless restoration of their services.

If connectivity never falters and it becomes something we don’t need to think about, then that’s progress that would benefit us all.
