Record error-free 5 Gb/s data transmission over 25 m of SI-POF is demonstrated in an LED-POF link using a PAM-32 modulation scheme. The APD-based receiver is shown to provide 8 dB greater link power budget over a PIN photodiode-based link.
The use of an APD-based receiver in a PAM-16 4 Gb/s LED-POF link is shown to provide 10 dB greater link power budget over a PIN photodiode link. Error-free transmission is achieved over 25m SI-POF.
The transmission performance of multi-channel adaptively modulated optical OFDM (AMOOFDM) signals is numerically investigated, for the first time, in optical amplification- and chromatic dispersion compensation-free, intensity-modulation and direct-detection systems incorporating directly modulated DFB lasers (DMLs). It is shown that adaptive modulation not only reduces significantly the nonlinear...
