Free Space Optics is a technology that transmits light directly through the air without a medium like fiber-optic cable. The technology uses laser light to transmit high-speed, point-to-point connectivity. This can be useful for overcoming challenges in deploying middle-mile broadband infrastructure where permitting or geographical features make fiber deployment difficult and protracted. #FreeSpaceOptics #X-Lumin #ProjectTaara

Problems we had with this 24 years ago: 1. You need a flat area or a long slow slope. 2. Air density. Some of the transceivers would see one way better than the other. Oddly enough people had difficulty seeing one way more that the other. 3. People built buildings in the way. 4. Some buildings had reflective surfaces so at certain times a day, we'd lose connectivity. 5. Heavy snow, fog 6. The transceivers on short distance LEDs couidn't be close to each other. This means that if I needed to send signal at 45 and 135 the tranceivers has to separated. In the end, we used it until we could get fiber there and then we removed them. I'm sure the new tech is better, but we never revisited it. Plaintree Wavebridge. Look it up.

Thanks for the comment. It looks like Wavebridge only used LED technology. I assume the laser technology used today would be much better and more reliable. It still would require line of sight, so a building being in the way is not the right application, unless you're delivering broadband to that building. A reflective surface of a building may be less of an issue with a laser. Heavy fog can still be problem. Apparently the size of droplets in fog is similar to the wavelength that FSO uses, which can causing attenuation from scattering. That is going to limit the distance that can be deployed. But, going over a railroad track or a river might be a good use case. Rivers often have fog over them, but maybe if the distance is short it won't be much of an issue.
