ABSTRACT:
A fiber optic repeater includes a photodetector stage, an amplification and pulse sharpening stage and a driven stage for an injection laser diode, the three stages being made up of only three MESFETs, preferably of the GaAs type and each stage being similar to the other stages in configuration so as to lend itself to MSI or LSI fabrication of a very simplified and reliable microwave frequency optical repeater.
