Paper Abstract

A miniturized D( to 300Mb/s optical transmitter and receiver modules have been developed. The optical transmitter utilizes an InGaAsP/InP surface emitting LED (the center wavelength is 1315nm) as a light source. The pulse width distortion is maintained less than ± 0.2nsec because the compensation circuit is employed to adjust the LED's response. The optical receiver utilizes an InGaAs/InP PIN-photodiode which responsivity is 0.82A/W for 62.5/125 GI 0.29NA fibers. Pre-amplifier using a Si-IC, has a transimpedance of 10kΩ and bandwidth of 200MHz. Automatic Threshold Control (ATC) circuit utilizes high speed peak-hold circuit technique to respond to burst signal within several handred nano-seconds. And in order to prevent the appearance of error pulses at extinct input, Automatic Threshold Bias-level Control (ATBC) circuit is employed. By the use of ATC and ATBC circuit, the receiver can receive the burst optical signal, which include a continuous extinct level, in short settling time and slight pulse width distortion.
