SK Telecom prepares for 100G


SK Telecom of Korea announced it will soon 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 operator has selected Nokia Siemens Networks‘ 100G-ready
optical network equipment for a cost-effective capacity expansion. The system
uses dense wavelength division multiplexing (DWDM), where a number of different
-colors’ or wavelengths of light transports data down the same optical fiber,
each carrying 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,” Tyler added.



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.
