UNITY serves as a key trans-pacific route for Telstra Global to service customers in and out of the Asia-Pacific region, and forms one of the core routes for its transmission and IP backbone worldwide.
The 100G technology is intended to meet the increasing business demands of Telstra's Trans-Pacific and Asia-Pacific customers.
It will be one of the first cables to be equipped with 100G technology, and the development represents a breakthrough in optimising 100G transmission over the 9,600km route from Japan to the US.
"This is just one the many projects we are working on to ensure our network is always growing, improving and providing world class services," said Martijn Blanken, Telstra Global's president and managing director.
"Demand for network services in the Asia Pacific region is growing exponentially. We are always working to deliver new technologies to ensure we have a strong connected Asia," he added.
UNITY is a five-fibre-pair trans-Pacific cable system linking the Chikura cable station in Japan with One Wilshere, the carrier building in Los Angeles.
