Technique for the reduction of optical beat interference in subcarrier multiplexed systems

Summary form only given. In conclusion, we have demonstrated that out-of-band clipping tones can be used to reduce optical beat interference (OBI), and give error-free transmission of QPSK signals. To perform this experiment we used a self-homodyne technique. This technique provides a simple way to...

Description
Summary:Summary form only given. In conclusion, we have demonstrated that out-of-band clipping tones can be used to reduce optical beat interference (OBI), and give error-free transmission of QPSK signals. To perform this experiment we used a self-homodyne technique. This technique provides a simple way to simulate worst-case OBI without relying on matching lasers.
