Abstract
We achieved 0.1397 dB/km at 1566 nm and 0.1406 dB/km at 1550 nm on a silica-core single-mode fiber. Both of them were 2 mdB/km lower than the previously recorded low-loss fiber in 2017. The improvement of the transmission losses was realized by the reduction of Rayleigh scattering loss. We estimated the system performance using the fiber figure of merit theory, and it was shown that the number of repeaters could be reduced by 2% compared to the previously recorded low-loss fiber. This ultra-low loss fiber is expected to improve the submarine transmission system more cost- and power- efficient.
期刊介绍：
The Journal of Lightwave Technology is comprised of original contributions, both regular papers and letters, covering work in all aspects of optical guided-wave science, technology, and engineering. Manuscripts are solicited which report original theoretical and/or experimental results which advance the technological base of guided-wave technology. Tutorial and review papers are by invitation only. Topics of interest include the following: fiber and cable technologies, active and passive guided-wave componentry (light sources, detectors, repeaters, switches, fiber sensors, etc.); integrated optics and optoelectronics; and systems, subsystems, new applications and unique field trials. System oriented manuscripts should be concerned with systems which perform a function not previously available, out-perform previously established systems, or represent enhancements in the state of the art in general.
