High speed WDM transmission on standard polymer optical fibers

We have developed WDM multiplexer and demultiplexer in the visible spectral range for POF transmission links and have carried out transmission experiments using different lengths of standard SI-POF. Our 4-channel WDM system with laser diode sources is operated in the violet, blue, green and red spectral range. Using discrete multitone modulation (DMT), we demonstrated a total data rate of 14.77 Gbit/s over 50 m and 8.26 Gbit/s over 100 m of SI-POF.
