The Evolution of Fiber Transmission in Optical Communications
Optical communication systems’ transmission capacity continues to be increasing forever. From telegraph systems carrying a few clicks per second a hundred years ago, towards the state-of-the-art, long-distance, DWDM Network systems carrying over one Tbps today, the capacity of wired long-haul systems has burgeoned in an average annual increase of around one third (or perhaps a […]
