Fiber optic links have been used to transport video signals for over a quarter of a century. Early fiber optic transport links often carried a very few analog channels over modest distances. Later, highly linear lasers and detectors were developed, increasing the channel count. Along the way, the use of single channel and multi-channel FM links rose and then declined sharply as wide bandwidth, highly linear analog links became affordable.
Today, analog fiber optic links remain popular for CATV applications, using one laser to carry up to 110 analog channels, plus hundreds of digital channels, over great distances. Fiber optic L-Band links (900 MHz to 2,200 MHz) ...
