stc, in collaboration with Huawei, successfully completed the first global 1.2T/channel trial in its Dense Wavelength-Division Multiplexing (DWDM) optical network.

The DWDM optical fiber technology is used to increase the bandwidth of existing fiber networks. The completion of the project reflects stc’s leadership and pioneering advantage in the ultra-high-speed transmission field and verifies the 1.2T/channel transmission capability on its live network.

The optical layer uses the Super C technology (120 channels in one pair of fiber), and the maximum single-fiber capacity can reach 48T, providing bandwidth assurance for Saudi Arabia's new services and applications such as e-government, smart healthcare and smart education, causing the acceleration of Saudi Arabia's digital transformation.

"stc Group has been the leader of the region in the field of optical transmission innovation and has paid a great attention to large-capacity transmission technologies," said Eng. Bader Allhieb, infrastructure VP of stc Group. "Huawei's 1.2T high-speed transmission technology maximizes the single-fiber capacity by 4 times and greatly improves the bearer efficiency of optical networks. In the future, stc Group and Huawei will continue to cooperate and explore the ultra-high-speed optical transmission field, accelerate the application of innovative technologies, construct more efficient optical networks and provide high-quality connection services to cope with explosive traffic growth."

The pioneering vision and leadership of stc Group in the digital market is a leading contributor to the success of Saudi Vision 2030’s aim for digitization and automation. As the digital market leader in Saudi Arabia, stc Group has been committed to modernizing telecom infrastructure, strengthening its technical advantages and network capabilities and ultimately providing an excellent user experience.
