Chinese researchers have set a new fiber optic transmission record. They achieved a total data rate of 51.3 terabits per second without repeaters.
The tests were conducted under conditions close to commercial networks. The key innovation was using hollow-core optical fiber.
Unlike traditional cables, light travels through an air channel inside the fiber. This reduces latency and increases potential capacity.
Engineers achieved 1.2 Tbps per wavelength. The total throughput reached 51.3 Tbps without any amplifiers.
This is the best result for spectral compression systems without remotely pumped amplifiers. An adaptive control system optimized power and speed.
