Abstract :
The effect of optical backreflection is measured on a 450-MHz optical link using a commercial Fabry-Perot laser without an isolator. With a low backreflection photodetector, the dynamic range of the Fabry-Perot link is comparable to a link with a high-linearity distributed feedback laser. With a standard photodetector, the dynamic range is 13 dB lower.
