This trajectory is expected to grow driven by 5G and IoT deployment and edge compute technologies.

Juno can meet the increasing demand for global internet bandwidth as existing Japan-US cables are nearing capacity.

“This new subsea cable is the latest joint effort NTT has led in a long and proud history of providing reliable global internet infrastructure.”

Japan, located midway between the US and key Asian markets, is considered the “Data Hub” in the Asia-Pacific region.

Juno is critical to support the global internet backbone, and further growth in Asia-Pacific countries and worldwide.

It offers several unique benefits to customers:

1. It will introduce SDM (Space Division Multiplexing) technology, enabling the provision of 20 optical fibre pairs (40 cores) per cable, (conventional technology currently provides a maximum of 16 fibre pairs or 32 cores).

2. It provides the maximum capacity of 350Tbps.

3. It offers resiliency by connecting to two separate landing stations in between Japan and the US, providing additional security and resilience against any potential disturbances due to rough weather conditions, particularly along the coastal areas of Japan.

4. Juno can alter the amount of bandwidth to each branch route according to demand and in response to customers’ evolving requirements.

5. Seren will provide network services to technology companies, OTTs, telecommunication carriers to strengthen the telecommunications environment in the US and Asia through sales, operations and management support.
