SK Telecom and NSN strike a deal

SK Telecom opts Nokia Siemens Networks' 100G-ready optical network equipment for a cost-effective capacity expansion. SK Telecom has plans to increase its network capacity by four times with 40 gigabits per second (40G) transmission and prepare its network for transition to 100G capacity in the future. The system uses dense wavelength division multiplexing DWDM to carry information at 40G.

“Korea is one of the most advanced broadband markets in the world, and is home to a vast number of growing smart device users. As data traffic continues to surge in this country, operators are considering plans for terabit optical transport networks or 100G,” said Paul Tyler, head of APAC region at Nokia Siemens Networks. “Nokia Siemens Networks has over 100 DWDM customers around the world and utilizes its technology leadership to ensure a superior end-user experience for SK Telecom customers.”

As part of the contract, Nokia Siemens Networks will deliver its hiT 7300 dense wavelength division multiplexing (DWDM) platform to SK Telecom. Based on the CP-QPSK modulation format, the company's coherent detection 40G transponder will utilize the operator's installed DWDM network infrastructure to transition to 40G line rate without the costly and time-consuming fiber measurement currently required by other systems.
