SK Telecom Upgrades Optical Network Capacity to 100G

SK Telecom, a South Korea based mobile operator, has upgraded its optical network capacity with Nokia Siemens Networks’ assistance. It has introduced 100G (gigabits per second) technology into its existing 40G network, to significantly increase its transmission capacity. The operator has deployed Nokia Siemens Networks DWDM (dense wavelength division multiplexing) 100G technology. The capacity expansion enables 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 8 Tbps (terabits per second) per fiber.
