Limits of the bit error rate (BER), information spectral efficiency and transmission reach are analyzed for an all-optical orthogonal frequency division multiplexing (AO-OFDM) with 200Gbaud/s symbol rate and quadrature phase-shift keying (QPSK) or quadrature amplitude modulation (QAM).
We propose and test a coherent all-optical orthogonal frequency-division multiplexing (AO-OFDM) system, based on all-optical (de)multiplexing and coherent detection, for multiterabit per second (multi-Tbit/s) passive optical networks (PONs). The proposed approach allows us to greatly increase the downstream data rate per user and extend the standard… (More)
We consider a simple and effective solution for unbundling the local loop in optical access networks, based on the orthogonal frequency division multiplexing technique, without coherent detection. The proposed architecture has a reduced power consumption and allows a flexible and scalable resource assignment among the operators and/or the users. System… (More)
We describe an innovative transceiver for both all-optical orthogonal frequency division multiplexing (AO-OFDM) and Nyquist wavelength division multiplexing (NWDM) systems, that allows flexible superchannel generation, by varying the number of the subcarriers, the modulation formats and the corresponding bit rates.
A novel high-capacity, energy-efficient and bit-rate flexible optical transceiver (Tx/Rx), capable of supporting rates from 10Gb/s to beyond 1Tb/s, has been designed and its performance in long-haul transmission has been carefully investigated. The device can realize both orthogonal frequency division multiplexing (OFDM) and Nyquist wavelength division… (More)
