Visible WDM System for Real-Time Multi-Gb/s Bidirectional Transmission Over 50-m SI-POF. IEEE Photonics Technology Letters, 28(15), 1696–1699.1041-1135https://hdl.handle.net/10016/33783We report a 2 Gb/s bidirectional real-time data transmission with bit error rate (BER) < 1 x 10(-10) in a 50 m step-index polymer optical fiber link. The system is able to transmit 5 Gb/s using five channels. The system performance is tested using the most restrictive channels with the shortest and longest wavelengths in a real-time Ethernet link. The implementation takes an advantage of the PAM-16 modulation spectral efficiency and low loss multiplexers and demultiplexers, which provide an enhanced link power budget. The optical power per transmitted bit considering the BER implication for TCP/IP networks throughput is below 5.8 pJ/b. This is due to the low insertion losses <4 dB, in each five-channel multiplexer and demultiplexer.4eng© 2016, IEEE.Polymer optical fiberVisibleWavelength division multiplexingGigabit transmissionTechnologyresearch articleElectrónicaTelecomunicacioneshttps://doi.org/10.1109/LPT.2016.2529703open access1696151699IEEE Photonics Technology Letters28AR/0000018116
