A 354-kilometer under-sea link in Indonesia, critical to the country’s international connectivity, has been upgraded by Nokia Siemens.

PT Telkom now benefits from bandwidth of 40 Gigabits per second (40G) per channel on its JaSuKa undersea cable between Dumai and Dangas, while reusing existing assets.

Nokia Siemens provided its optical networking equipment to deliver the world’s longest 40G link deployment without intermediate amplifiers. With currently four 40G channels - or wavelengths of light - in operation, the link’s maximum information carrying capacity has been increased over 16 times.

The link carries fixed and mobile voice and data traffic from PT Telkom and other major operators of Indonesia, many of them employing elements of Nokia Siemens Networks’ Liquid Net architecture.

“This initiative is part of our vision to develop the Nusantara Super Highway to provide ‘true’ broadband to 90% of capital districts across the Indonesian Archipelago by 2015. We are upgrading our terrestrial network to 40G to cope with the increased demand for bandwidth-intensive applications and services. The JaSuKa undersea cable is critical for international connectivity and we felt it was time to increase its capacity too,” said David Bangun, executive general manager of Telecommunication Infrastructure Division at PT Telkom.

Under the contract, Nokia Siemens also provided implementation services such as survey, installation, commissioning and integration for the DWDM equipment. The company used its end-to-end project management expertise for rapid deployment of the network, helping the operator achieve its targeted return on investment.
