Abstract

A record continuous transmission bandwidth of 16.4 THz is demonstrated in O-band fibre transmission over an 80-km single-mode ultra low-loss fibre span. Bismuth-doped fibre amplifiers with an output power of 25 dBm and a low noise figure of 3.6 dB compensate a loss of 80-km fibre span. An O-band wavelength selective switch with a 16.4 THz bandwidth maximises the transmission capability and enabled optimisation of the input spectrum shape to reduce nonlinear interference near zero dispersion, resulting in a potential achievable information rate of over 100 Tb/s to be reached.

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.
