As a next-generation communication key technology, hollow-core fiber has been deployed on a large commercial scale for the first time between intelligent computing centers 30 kilometers apart in Zhongwei, Ningxia. By embedding a micro glass cylinder structure inside, this technology provides a low-loss, high-speed transmission channel for optical signals.
With the explosive growth in demand for computing power driven by large model training and inference, cross-regional computing power scheduling has become the norm. Traditional optical fibers face latency and loss bottlenecks in long-distance transmission, while hollow-core fiber reduces latency and loss by over 30%, effectively alleviating the ultra-high latency problem caused by distance between Ningxia and computing power demand regions such as the Beijing-Tianjin-Hebei area.
The implementation of this technology provides key infrastructure support for building a computing power network with ultra-low latency and ultra-large bandwidth. In the future, the large-scale promotion of hollow-core fiber is expected to further optimize the transmission efficiency of the national integrated computing power network, helping the AI industry achieve flexible allocation of computing power resources across a broader geographical scope.
