Rationale of OCDMA/OFDMA for NG-PON

Abstract

There will be good motivation to pursue OCDMA and OFDMA technology as promising options for NG-PON2 other than TDMA and DWDMA. Rationale behind it will be discussed.

Single and multirate FFH-OCDMA networks based on PSK modulation formats

“…All of these requirements can be fully satisfied by joining the PON architectures with the OCDMA technique in order to constitute the passive optical code-division multiple-access (OCDMA-PON). OCDMA-PON networks also have several other remarkable attributes, such as asynchronous access, capacity on demand, lower cost/complexity for new users, the possibility of offering virtual point-to-point technology, high scalability, security, flexibility in code projects, and support for multiple data rate transmission at the physical layer [10]- [14].…”
