Hollow-core fiber uses air as the transmission medium, replacing the traditional optical fiber that uses "glass core" as the transmission medium. With ultra-low latency, ultra-low nonlinearity, potential ultra-low loss and wider passband bandwidth, hollow-core fiber can help OTN systems achieve greater transmission capacity, longer transmission distance, and smaller transmission time delay.

The pipe hole resources of underground communication pipelines are basic communication resources in short supply for operators. Except for newly built roads and roads in development zones, the occupancy rate of pipe holes on other roads is generally high.
