Abstract
The design, construction, and performance of a practical optical link with interface circuits for coding and decoding 1.5-Mb/s, bipolar, digital signals are described. The optical devices used are light-emitting diodes and PIN photodiodes. A feedback or “transimpedance” preamplifier that incorporates a silicon junction-field-effect transistor is used in the receiver, which has a sensitivity of −57.2dBm average optical power for a 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−9</sup> bit-error-rate. The receiver demonstrates an optical power dynamic range of about 28 dB without requiring automatic gain control. Timing recovery is accomplished by a simple, conventional technique.
