Abstract :
We propose a tunable encoder/decoder based on polarization modulation for the spectrum amplitude coded-optical code-division multiple access (SAC-OCDMA) passive optical network (PON) and experimentally demonstrate its coding/decoding performance for the first time. The experiment result verifies that the encoder/decoder with 40-dB blocking ratio can fully suppress the unwanted spectral slices and performs good coding/decoding capability. Code length of 45 and code weight of 9 are demonstrated for proof-of-concept.
