Phase II reconfigurable incoherent OCDMA testbed

  • Introduced the concept of M-ary (multi-symbol) OCDMA to increase spectral efficiency
  • Demonstrated 10 Gb/s usingoptical encoded PPM (M-ary) with M = 4, 6 users
  • INtegrated, computer-controlled tunable delay lines allowed receiver to tune to any transmitter code
  • Scalability analysis shows 31 simultaneous users
  • Also demonstrated asynchronous, incoherent OOK operating at 5 Gb/s with 8 users @ 10-9 BER
