New Method Achieves Beyond Terabit/s Transmission Using Hollow-core Fibers

Recent advancements in optical communication have been highlighted in a new paper titled "Demonstration of Beyond Terabit/s/lambda Nonlinearity-free Transmission over the Hollow-core Fibre" by Yang Hong and colleagues. The study presents a method for transmitting signals at speeds exceeding one terabit per second per wavelength through hollow-core fibers (HCF), which are known for their low loss and reduced nonlinearity compared to traditional single-mode fibers (SMF).

The research indicates that the HCF-based optical recirculating loop achieved approximately 17.4% higher capacity than the SMF-based loop at a launch power of 23 dBm after 25 loops. Additionally, both laboratory experiments and field trials demonstrated that HCF exhibited about 1.6 microseconds per kilometer lower latency than SMF. This reduction in latency is significant for applications requiring high-speed data transmission, such as telecommunications and data centers.

The findings suggest that hollow-core fibers could play a crucial role in the future of optical communication systems, particularly as the demand for higher data rates continues to grow. The study was presented at the 50th European Conference and Exhibition on Optical Communication (ECOC 2024).
