https://www.tarluz.com/wp-content/uploads/2015/10/FTTx-technology.jpg585468Optical fibre has incredibly low loss coupled with extremely high capacity, making it a unique transmission medium. From the point of view of the access network The Shannon Limit can effectively be ignored. Distance is not an inherent limitation as optical signals can travel 70–80 km before they need to be amplified. Instead the limitations […]
