SUBCO Deploys Ciena to Provide a Secure Gateway from Australia to Europe

Leveraging Ciena GeoMesh Extreme, the Oman Australia Cable boasts lower latency, reliability, and security

Following the successful upgrade on the Indigo Submarine Cable, SUBCO is once again using Ciena (NYSE: CIEN) technologies to provide a resilient and reliable undersea corridor between Australia and Europe via the Oman Australia Cable (OAC). Leveraging Ciena GeoMesh Extreme, powered by WaveLogic 5 Extreme in the 6500 Packet-Optical Platform, OAC has now increased its capacity to a maximum of 48Tb/s, helping support increased bandwidth demands.

“We have a long history of working with Ciena and, together, we are proud to provide our customers with an express gateway for onward capacity from Australia to Africa, Europe, and the Middle East. OAC provides the market with the most secure and diverse route to connect Europe with Asia Pacific and is important in boosting Australia’s digital resiliency,” said Lee Harper, Chief Operating Officer, SUBCO.

“Security and reliability are important to SUBCO as OAC prides itself as an alternative for moving traffic from Asia Pacific to Africa, Europe, and the Middle East, and promotes Australia’s role as a digital hub. With Ciena’s GeoMesh Extreme solution, SUBCO can keep pace with proactive bandwidth requirements and reactive performance demands while guaranteeing overall network availability,” said Ivan Polizzi, Regional Managing Director, Ciena Australia, New Zealand and the Pacific.

Launched for commercial service in November 2022, OAC is a 9,800km submarine cable connecting Muscat, Oman, and Perth, Australia, with an alternate path that leads from Salalah, Oman into Europe and Africa to be ready by 2024.
