Passive splitting of optical transmission lines result in high additional system attenuation, proportional to the amount of desired clients. Splitting an optical signal, using a one to eight star coupler with bi-direction data transmission over a single POF, results in a splitting attenuation of about 28.5 dB. Adding a transmission line of 100 m SI-POF results in an overall system attenuation of 35.5 dB at 530 nm. Achieving flexible and robust data transmission with the given system requires a specialized signal modulation. Therefore, a basic frequency modulation is used to convert the data to an analog signal that is then modulated and transmitted over POF. Demodulation and synchronization of the analog signal are done by a FFT (Fast Fourier Transform). Using frequency modulation with high performance optical receivers, data can be transmitted over a distance of up to 400 m with an approximated BER of about 1.6×10-2 and a data rate of 781,25 kBit/s.
