Abstract
In this tutorial overview, the principles, advantages, challenges, and
practical requirements of optical orthogonal frequency division multiplexing
(OFDM)-based optical access are presented, with an emphasis on orthogonal
frequency division multiple access (OFDMA) for application in
next-generation passive optical networks (PON). General OFDM principles,
including orthogonality, cyclic prefix use, frequency-domain equalization,
and multiuser OFDMA are summarized, followed by an overview of various
optical OFDM(A) transceiver architectures for next-generation PON.
Functional requirements are outlined for high-speed digital signal
processors (DSP) and data converters in OFDMA-PON. A techno-economic outlook
for such a “software-defined,” DSP-based optical access platform
is also provided.
