With increasing smartphone adoption in Korea, there is a surging demand for higher capacity networks. Korea’s mobile operator SK Telecom (News - Alert) is trying to match this demand by significantly increasing its transmission capacity. The company has chosen Nokia Siemens Networks’ DWDM (dense wavelength division multiplexing) 100G technology and related services.
For the capacity expansion, Nokia Siemens Networks (News - Alert) is providing its hiT 7300 DWDM platform. The platform will be using the installed network infrastructure by using coherent transmission technology, allowing the operator to cost efficiently carry out the mission. This transmission technology is based on a modulation format called CP-QPSK or coherent polarization multiplexed quadrature phase shift keying.
In addition, Nokia Siemens Networks has agreed to offer its network management system to ensure simplified network operations and comprehensive network performance monitoring for SK Telecom. The company also will be offering its network planning, optimization and implementation as well as hardware and software maintenance care services for the project.
“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,” Tapani Sairanen, head of Asia and Middle East cluster, customer sales support, Optical Networks, Nokia Siemens Networks said in a statement.
“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 broadband customer experience,” Sairanen added.
The capacity expansion will help 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 eight terabits per second per fiber.
Back on December 3, 2012, Nokia Siemens Networks and Marlin Equity Partners announced that they reached an agreement for Nokia Siemens Networks to sell its Optical Networks business unit to Marlin Equity Partners.
