| Résumé : |
Local computer networks which communicate over copper conductors have been developed both to promote resource sharing and provide increased performance.
in this report the use of fibre optics in such networks is considered, and a status report on the optical fibre network experiment which operates at 1Mbit/s and 10Mbit/s is given.
The system performance of the Optical Ethernet experiment, which uses an LED with power output control possibility, multimode step index fibre, PIN photodiode, and incorporating a collision-detection-device is described.
Circuitry developed for each sub-system is presented with its characteristic curves and output waveforms for a specific input signal.
The performance of the receiver used is examined, the noise present in the unit, the minimum power required are measured as well as the value of its sensitivity for a SNR of 21.6dBm which yields a BER of 10⁻⁹ .
Finally suggested circuit for measurement of the BER is presented as an expansion possibility for this project. |
