SK Telecom Upgrades Optical Net to 100G with NSN

SK Telecom, the largest mobile operator in Korea, is upgrading its optical transmission backbone to 100G using DWDM equipment from Nokia Siemens Networks.

NSN is providing its hiT 7300 DWDM platform, enabling SK Telecom to scale the network 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 per fiber.

In addition, Nokia Siemens Networks provides its network management system, along with network planning, optimization and implementation as well as hardware and software maintenance care services for the project. Financial terms were not disclosed

“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. 

  • On December 3, 2012, Nokia Siemens Networks and Marlin Equity Partners announced 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.
