SK Telecom to deploy 100G through Nokia Siemens Networks

07 January 2013 | Kavit Majithia


Korean operator SK Telecom has started to introduce 100G to increase its optical network capacity on its existing 40G network.

In a bid to increase its transmission capacity, the operator has partnered with the vendor to deploy Nokia Siemens Networks’ DWDM technology.

The deal will enable SK Telecom to simultaneously transmit 80 wavelengths of light, each carrying data at 100G on a single optical pair, giving total capacity of up to 8Tbps per fibre.

“With increasing smartphone adoption in Korea, there is 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 optimising the use of existing fibre,” said Tapani Sairanen, head of Asia and Middle East, customer sales support, optical networks at NSN.

“This ultra-fast data transmission allows SK Telecom to continue to ensure a superior mobile broadband customer experience.”

NSN is providing its DWDM platform to utilise the installed network infrastructure, and by using coherent transmission technology, it is able to protect operator investment.

NSN will further provide a network management system to ensure simplified network operations and comprehensive network performance monitoring for SK Telecom.

The partnership also provides SK Telecom with its network planning, optimisation and implementation, as well as hardware and software maintenance.

In December 2012, NSN reached an agreement with Marlin Equity Partners for the company to sell its Optical Networks business unit to the financial group. The network solutions unit will be established as an independent company.
