Abstract

The performance and design of fiber-optic links for analog signal transmission at microwave frequencies are discussed. The effect of impedance matching the fiber-optic transceiver using either lossless or lossy circuit elements is presented. In particular, the following performance parameters are examined: link insertion loss, transceiver input and output VSWR, and link bandwidth. The contributions of RF circuit losses as well as optical losses to the overall RF link insertion loss are described. Commercially available fiber-optic links are shown to be unsuitable for most microwave applications. However, fiber-optic links employing lossless impedance matching to the laser diode and photodiode are shown to minimize the link insertion loss and VSWR in a finite frequency band and are therefore practical for many applications involving microwave signal transmission.
