Introduction of Optical Networking
Optical networking began its development in the 1970s and has since grown to become the technological backbone of today's telecommunications infrastructure. The earliest long-distance fiber optic networks could transmit data over distances of up to a few kilometers using LED light sources. However, it was the invention of continuous wave and pulsed lasers in the 1960s that enabled optical signals to travel much farther without amplification, laying ... Read more
