China Mobile Deploys First Three-Band Multi-Core Optical Cable Line
China Mobile has successfully deployed the world's first S+C+L three-band multi-core optical cable line in Qingdao, an innovation developed with industry partners. This new optical fiber technology uses a four-core structure to expand single-core bandwidth by nearly 50%, with a single optical fiber's capacity exceeding five times that of traditional fiber. This development aims to meet future demands for AI computing and terabit-level ultra-high-speed data transmission.
Key Takeaways
- China Mobile deployed the world's first S+C+L (short, conventional, long wavelength) three-band multi-core optical cable line in Qingdao.
- The new optical fiber uses an innovative four-core structure, integrating four independent signal channels within a single fiber.
- This technology expands single-core bandwidth by nearly 50% and increases a single optical fiber's capacity by over five times compared to traditional fiber.
- The development extends ultra-low-loss and large effective area characteristics to the S band, enabling three-band parallel transmission.
Why It Matters
The deployment of China Mobile's S+C+L three-band multi-core optical cable line significantly boosts network capacity, addressing the growing demands of AI computing and ultra-high-speed data transmission within streaming infrastructure. This advancement allows for a substantial increase in data throughput per fiber, potentially reducing infrastructure costs and improving performance for demanding video applications. It highlights the ongoing race to scale global network backbones to accommodate exponential data growth. Industry participants should monitor how quickly these multi-band, multi-core fiber technologies are adopted and standardized beyond initial deployments to anticipate future network capabilities.
