We developed an analytic characterization of the steady-state throughput of a free-space optical satellite communications (FSOSC) system which includes an ultra-high-speed transmission control protocol for FSOSC (TCP-FSO) and an adaptive- distributed

Performance instabilities due to the fading are vital subjects for long distance free space optical communication systems in which the signal lights travel through the atmosphere. The straightforward approach is to introduce the combinations of optic

In order to stably achieve high throughputs in the satellite-to-ground free space optical communication systems, suppression of the influence of the fading due to atmospheric turbulence is an important technical subject to be overcome. Our group has

C-band and L-band wavelength division multiplexing (WDM) transmission performance was improved by using bidirectional signal assignment (BSA) to reduce crosstalk (XT) in square lattice structure 16-core fiber. Transmission of 16 WDM channels with 256

We report investigations on the mode diversity receiver applied in optical links from low-earth-orbital satellites to a ground terminal. We numerically simulated temporal power variations coupled to each mode of a FMF under atmospheric turbulence at

We proposed and evaluated the effectiveness of a simple rate control technique of Adaptive Distributed Frame Repetition (ADFR), which achieves both high speed link in the stable condition and suppresses the influence of turbulence-induced fading in t

We investigated the performance of mode diversity reception of a polarization-division-multiplexed (PDM) signal with few-mode-fiber (FMF) coupling for high-speed free-space optical communications under atmospheric turbulence. Optical propagation thro

We demonstrate crosstalk reduction using bidirectional signal assignment on WDM transmission of 256 Gb/s PM-16QAM over square lattice structure 16-core fiber. Mixed SSMF and MCF transmission with 6 spans of MCF is possible with Q crosstalk penalty be
