- Abstract :
A block-ciphered (M-ary) optical code division multiplexing (OCDM) can provide
larger security than a conventional OCDM system based on bit ciphering. We propose a
polarization multiplexed (POL-MUX) M-ary OCDM system and demonstrated 2.5 Gbps,
POL-MUX 256 (=16X16)-ary OCDM transmission using a single multi-port optical
encoder/decoder (E/D). We show that this architecture reduces the number of required
optical codes and enhances the system confidentiality.
