Free Space Optics (FSO) is a technology that transmits data, video or voice, using laser beams via a line of sight optical bandwidth connection. 5Gbps, and at frequencies above 300GHz, with. By enabling high-data-rate inter-satellite links, secure UAV–ground channels, and efficient HAPS backhaul, FSO technology is paving the way for sustainable 6G non-terrestrial networks. However, the stringent requirement for precise line-of-sight (LoS) alignment between the optical transmitter and. Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking over long distances. "Free space" means air, outer space, vacuum, or something similar. This contrasts. CableFree: Wireless Excellence has pioneered reliable, carrier-class Free Space Optics (Optical Wireless) equipment, with thousands of commercial deployments in diverse markets since 1997. We hold the longest track record of commercial FSO vendors, and widest global deployment. Our CableFree range. Free-Space Photodetector Modules feature biased or amplified Si diodes, or a high speed InGaAs diode that cover the UV, VIS, NIR, and SWIR spectra from 200 – 1700nm. These detectors provide fast rise times and bandwidths for immediate detection for pulsed lasers, the Si version features 1ns rise. Our design solutions for free space optical systems development include optical framing protocols and simulation/emulation for various optical communications channels. air, a vacuum or even outer space.
