Noise Analysis and Multi-Gbit/s Transmission in PoF Scenarios over SI-POF

In this work the delivering of optical power with several mW simultaneously with Gigabit data transmission in step-index plastic optical fiber is reported. Theoretical analysis of the signal-to-noise ratio of data signal at 650 nm is presented to study the influence of the feeding power at 405 nm on the data traffic. We experimentally explore this influence on a real-time Ethernet link at a speed of 1 Gbit/s using commercial products. The system performance was tested at 650nm and a low loss designed multiplexer was used to enhance the power budget of the system. The system was able to deliver several mW of optical power in coexistence with data transmission at 1Gbit/s and BER ~ 1×e-10
