Hollow Optical Cable Construction
Hollow core fiber (HCF) is an optical fiber that uses air as its transmission medium. This reduces latency to around 3. 5 microseconds per kilometer, offering a 30 to 50 percent speed increase. "Hollow core fiber represents the next revolution in optical networking, offering unprecedented speeds and lower latency that traditional fiber simply cannot match," says Dr. Winston Schoenfeld, vice president for research and innovation at the University of Central Florida. These features make them very promising for. -gas recovery, 5G x-haul mobile networks, and intra-data center interconnection. Low latency can be achieved by straight transmission line connection, minimization of equip ent delay, and optimizing DSP in transceivers, or use of wireless communication.
