Journal ArticleDOI
Modeling of Fog and Smoke Attenuation in Free Space Optical Communications Link Under Controlled Laboratory Conditions
TL;DR: In this paper, the authors theoretically and experimentally investigate the spectrum attenuation of free space optical (FSO) communication systems operating at visible and near infrared (NIR) wavelengths.
Journal ArticleDOI

TL;DR: The design and fabrication of integrated transmitter and receiver components are reported and a preliminary result of a MIMO system implementation operating at a data rate of 1 Gbps is demonstrated.
Journal ArticleDOI
Performance Analysis of Ethernet/Fast-Ethernet Free Space Optical Communications in a Controlled Weak Turbulence Condition
TL;DR: In this paper, the performance of the Ethernet and Fast-Ethernet free space optical (FSO) communications link under the influence of the weak atmospheric turbulence is investigated and a dedicated experimental indoor atmospheric chamber is used to generate and control the turbulence conditions that affect the FSO link performance.
Journal ArticleDOI
Enhancing the Atmospheric Visibility and Fog Attenuation Using a Controlled FSO Channel
TL;DR: In this paper, two methods for characterizing fog attenuation in terms of atmospheric visibility V in free space optics (FSO) communications are analyzed and compared using a charge-coupled device (CCD) camera and a laser-diode at 0.55 μm.
Journal ArticleDOI
Ethernet FSO Communications Link Performance Study Under a Controlled Fog Environment
TL;DR: Results shown indicate that the 4-PPM signalling scheme is the most robust to the fog attenuation due to its high peak-to-average power ratio and shows the potential of the indoor atmospheric chamber to replicate outdoor atmospheric effects (such as fog) and be able to quickly characterise and assess the FSO system under a controlled environment.
