Indonesia under-sea fiber link gets huge capacity boost


Telkom, Nokia Siemens Networks deliver world’s longest repeater-free 40G channel submarine link




A 354 kilometer under-sea link in Indonesia, critical to the country’s international connectivity, has been upgraded by Nokia Siemens Networks. PT Telekomunikasi Indonesia (PT Telkom), the largest telecom operator in Indonesia, 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 Networks 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 Telekomunikasi Indonesia. “Nokia Siemens Networks proposed a solution that made the most of our existing investments, delivering a high quality, cost-effective and reliable 40G network on time.”




“Indonesia is witnessing a rapid uptake of broadband services. With ever-increasing wireline and mobile broadband penetration and the roll-out of new services, operators need to ensure round-the-clock connectivity for end users,” said Salman Zafar, head of PT Telkom customer team at Nokia Siemens Networks. “By investing in the optical undersea link that carries international telecoms traffic, whether it’s mobile or fixed, PT Telkom is well prepared to meet the increase in demand.”




Nokia Siemens Networks provided its dense wavelength division multiplexing (DWDM) solution**, comprising the hiT 7300 optical network platform, which is part of the company’s Liquid Transport architecture. The hiT 7300 platform aims to provide cost savings by either adopting no dispersion compensation (DCM-free) techniques on new fiber or simply by utilizing the operator’s installed DWDM network infrastructure. The latter option enables operators to benefit from higher capacity without the costly and time-consuming fiber measurement required by conventional systems***.




Nokia Siemens Networks’ network planning tools simplified the project’s design phase, and its network management system is managing the JaSuKa backbone network.




Under the contract, Nokia Siemens Networks 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.

*JaSuKa is an abbreviation for Jawa Sumatra Kalimantan – the three main islands of Indonesia. JaSuKa is a project inside PT Telkom and has extensions since several years. Nokia Siemens Networks is a partner from the very beginning and started deployments with this project with hiT 7500. PT Telkom is DWDM partner even earlier: Nokia Siemens Networks deployed WL8 in the end of the last century.




**Part of the company’s Liquid Transport architecture, Nokia Siemens Networks’ DWDM solution, comprising the multihaul hiT 7300 system and a DWDM planning tool, provides a cost optimized, flexible and automated platform for optical networking, thereby offering a viable answer to excessive traffic demand, reconfiguration and cost pressure issues. The design principle of the hiT 7300 is based on high modularity on a single platform ranging from metro to core. It also provides network operators with a new level of simplicity for commissioning and managing DWDM systems, driving out complexity, while providing complete administrator control. Nokia Siemens Networks’ end-to-end planning tool provides optimal network design, guaranteed performance and automated configuration, resulting in significant OPEX savings as well as reduced outage time and procedural errors along with an exceptionally low TCO.




***Using the CP-QPSK (coherent polarization multiplexed quadrature phase shift keying) modulation format, the transponder integrated into hiT 7300 detects not only an optical signal’s amplitude, but also its phase and polarization. Its enhanced detection capability brings superior performance at highest bit-rates, even in presence of transmission impairments.
