A detailed study on the effectiveness of three proposed optical orthogonal frequency-division multiplexing (OOFDM) adaptive loading algorithms (ALAs) is conducted, addressing, for the first time, a number of crucial issues related to OOFDM directly modulated laser-based intensity-modulated and direct-detected passive optical networks (PONs). The ALAs(More)
The Peak-to-Average Power Ratio (PAPR) and Optical Beat Interference (OBI) is examined thoroughly in Orthogonal Frequency Division Multiplexing Access (OFDMA)-Passive Optical Networks (PONs). Four techniques for mitigating the PAPR/OBI problem are evaluated, namely the bit-loading algorithm and clipping for the PAPR, and the power-loading and thermal(More)
The peak-to-average power ratio (PAPR) and optical beat interference (OBI) effects are examined thoroughly in orthogonal frequency-division multiplexing access (OFDMA)-passive optical networks (PONs) at a signal bit rate up to $$\sim 20\,\mathrm{{Gb}}/{\hbox {s}}$$ ∼ 20 Gb / s per channel using cost-effective intensity-modulation and direct-detection(More)
Detailed investigations of the effectiveness of three widely adopted optical orthogonal frequency division multiplexing (OOFDM) adaptive loading algorithms, including power loading (PL), bit loading (BL), and bit-and-power loading (BPL), are undertaken, over < 100km single-mode fibre (SMF) system without incorporating inline optical amplification and(More)
A quantitative comparison of up to 40 Gb/s low-cost orthogonal frequency-division multiplexing access (OFDMA)-passive optical networks (PON) implementations for both upstream (US) and downstream (DS) directions is evaluated based on different modulation and detection techniques.
