Cloud computing enables on-demand access to shared computing resources, allowing organizations to quickly provision and release capacity with minimal management effort. Its adoption is increasing as businesses migrate IT infrastructure to the cloud to enhance scalability, cut costs, and improve efficiency. Ultra-low-loss fiber supports this trend by enabling high-speed, reliable long-distance data transmission with minimal signal loss, improving data center interconnectivity, reducing latency, boosting bandwidth efficiency, and ensuring seamless delivery of cloud services worldwide. For example, in October 2025, according to AAG IT Services, a UK-based IT and digital transformation services company, public cloud services experienced a revenue surge, surpassing $415 billion in 2022, with forecasts indicating growth to $526 billion in 2023. Therefore, the proliferation of cloud computing is driving the growth of the ultra-low-loss fiber market.

Industry leaders are advancing optical fiber technology to meet the needs of 5G networks and rising global data traffic. Multi-core fibers, which contain multiple cores within a single cladding, significantly increase transmission capacity without enlarging cable size, improving efficiency and reducing infrastructure costs for high-capacity applications such as 5G, data centers, and submarine communications. In September 2023, Sumitomo Electric Industries Ltd., Japan, introduced the world’s first mass-produced ultra-low-loss multi-core fiber, offering a transmission loss of just 0.158 dB/km at 1550 nm and low inter-core cross-talk. This innovation doubles transmission capacity without increasing cable size, enabling next-generation optical networks capable of handling growing cloud service usage, 5G expansion, and surging global data traffic.

Ultra-low-loss fiber is a specialized type of optical fiber engineered for exceptionally low signal attenuation, generally below 0.17 dB/km. It is produced using ultra-pure materials and advanced manufacturing processes that significantly reduce light scattering and absorption. This type of fiber enables long-distance optical transmission with high efficiency and excellent signal quality, supporting high-capacity networks while minimizing the need for frequent signal amplification.

The primary types of ultra-low-loss fiber include single-mode and multi-mode fibers. Single-mode fiber features a very small core that transmits light over long distances with minimal loss and high bandwidth. These fibers are manufactured from materials such as silica, plastic, and other substances. They are applied in areas including telecommunications, data centers, submarine cable systems, military and aerospace sectors, industrial uses, and more. Key end-users include telecom operators, internet service providers, enterprises, government bodies, and other organizations.
