Paper Details

This work is based upon the concept of enlightenment and communication using laser. The dependency onwavelength of silicon photodiode (Si PD) used in the optical communication is studied by means of simulation. Thesensitivity of the silicon photodiode is compared for three wavelengths corresponding to Red (680nm), green (550nm)and Blue (450nm).The performance of red is high as compare to green and blue at different weather condition. VisibleLight Communication is an upcoming field in the communication world. It will provide highest band width, high refuge,efficient power transmission and less spin as compared to all other wireless networks. The major challenge on VisibleLight Communication technology is atmospheric attenuation that hampers data transmission of the system by increasingbit error rate. Fog is the distinctive condition which causes highest amount of signal weakening. Signaling rate is takenis 5Gbps, transmitting power is 15 mW and NRZ encoding technique is taken during transmission, transmitter channel isFSO and for reception a PIN photodiode with Bessel filter is taken. This paper primarily describes the effect of badweather condition on FSO link within 100m range for an attenuation of up to 80 dB/km. Simulation parameter such asQuality factor, minimum BER(bit error rate) and Eye diagram are studied to have the idea of system performance usingOPTISYSTEM 12.0 of optical software.
