[en] A versatile fiber optic system of outstanding performance has been designed and utilized in the development of the CPRF pulsed power equipment. These fiber optic systems consist of a family of interchangeable, but application oriented, mother and daughter PC boards. Furthermore, a self contained, chassis, or ''CAMAC'' format of links are available. The transmitter family may be described as having a true instrumentation amplifier front end (of unique design), a temperature compensated V/F converter, and fiber optic and differential current loop outputs. The receiver family consists of various mother and daughter boards which can easily be interchanged to optimize overall system requirements. The receivers are temperature compensated and capable of driving 50Ω loads to full output. Receivers boast a better than 67 dB S+N/N ratio without any noticeable overshoot or ringing. A no input ''shutdown'' and a ''remote flag'' feature is used to protect sensitive or control hardware. The overall link performance can be typified by having a bipolar ''pick ampersand mix'' accuracy of better than .5% from all causes; offset, drift, non-linearity, and thd. Hand-picked pairs easily achieve better than .2% bipolar accuracy. A unipolar circuit can easily be set to ''0'' error, with less than .5 mV/degree C offset. Presented will be the detailed design information along with examples of application specific hardware. 11 figs., 1 tab
