SK Telecom increases optical network capacity to 100G
Seoul, Korea – January 7, 2013
Selects Nokia Siemens Networks' optical network equipment to provide 8 Tbps per fiber
SK Telecom, the largest mobile operator in Korea, has started to introduce 100G (gigabits per second) technology into its existing 40G network, to significantly increase its transmission capacity. To do this, the operator has selected Nokia Siemens Networks' DWDM (dense wavelength division multiplexing)* 100G technology and related services. The capacity expansion enables SK Telecom to simultaneously transmit up to 80 wavelengths of light, each carrying data at 100G on a single optical fiber, giving a total capacity of up to 8 Tbps (terabits per second) per fiber.
"With increasing smartphone adoption in Korea, there is a surging demand for higher capacity networks. Operators such as SK Telecom need to expand their network capacity multifold, and they need to do so cost efficiently by optimizing the use of existing fiber," said Tapani Sairanen, head of Asia and Middle East cluster, customer sales support, Optical Networks, Nokia Siemens Networks. "Our scalable and flexible optical products help SK Telecom transition to a 100G network cost efficiently, as our technology eliminates the need for costly installation of more fiber. This ultra-fast data transmission allows SK Telecom to continue to ensure a superior mobile broadbandcustomer experience."
For the capacity expansion, Nokia Siemens Networks is providing its hiT 7300 DWDM platform. The platform utilizes the installed network infrastructure by using coherent transmission technology, thereby protecting the operator's investments. This transmission technology is based on a modulation format called CP-QPSK (coherent polarization multiplexed quadrature phase shift keying)**.
In addition, Nokia Siemens Networks provides its network management system to ensure simplified network operations and comprehensive network performance monitoring for SK Telecom. The company also provides its network planning, optimization and implementation as well as hardware and software maintenance care services for the project.
On December 3, 2012, Nokia Siemens Networks and Marlin Equity Partnersannounced that they had reached an agreement for Nokia Siemens Networks to sell its Optical Networks business unit to Marlin Equity Partners. The announcement outlined that the deal would result in the unit being established as an independent company with the goal of becoming a leading provider in the optical market.

* Comprising the hiT 7300 and TransNet DWDM planning and automation tool, Nokia Siemens Networks' DWDM offering provides a cost optimized, flexible and automated platform, thereby offering a viable answer to excessive traffic demand, reconfiguration and cost pressure issues. The design principle of the DWDM platform (hiT 7300) is based on high modularity as well as high re-use, thus creating a single platform from metro to core. It also provides network operators with a new level of simplicity for commissioning and maintaining DWDM systems, driving out complexity while providing complete administrator control. Nokia Siemens Networks' TransNet end-to-end planning tool provides optimal network design, guaranteed performance and automated configuration, resulting in significant operational expenditure savings as well as reduced outage time and procedural errors along with an exceptionally low Total Cost of Ownership.With over 100 DWDM customers around the world, Nokia Siemens Networks provides a migration path to Terabit Optical Transport. It also provides scaling capacity for channels of 10/40/100 Gbps, with its platform being open to 400Gbps and even more.
** 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 the presence of transmission impairments.
