“…The electro-optic modulator normally employed for downlink transmission in hybrid LR-FTTH is the Mach-Zehnder modulator (MZM), due to the electro-optic bandwidth available. In the works that have been reported in the literature about transmission of OFDM signals, chirpless Manuscript operation of the MZM has been considered [3]- [5]. Intensitymodulation direct-detection (IMDD) OFDM transmissions using chirped electro-optic devices, such as electro-absorption modulator [6], semiconductor optical amplifiers [7] have been reported.…”

We investigate the transmission performance of an optical signal composed by a custom orthogonal frequencydivision multiplexing (OFDM) gigabit ethernet (GbE) signal, a long-term evolution (LTE) signal, and an OFDM ultrawideband (OFDM-UWB) signal, when chirp is introduced in the intensity modulation based on a dual electrode Mach-Zehnder modulator. The results show that, when the optical signal is generated with controlled negative chirp, it is possible to reduce the optical signal-to-noise (OSNR) penalty after transmission through a long reach fiber-to-thehome network by approximately 5, 1.5, and 0.5 dB, for the OFDM-UWB, LTE, and OFDM-GbE signals, respectively. Furthermore, the results show negative OSNR penalty for OFDM-UWB and LTE signals after transmission, for specific distances.Index Terms-Chirp, dispersion compensation, dual electrode Mach-Zehnder modulators (DEMZM), hybrid long reach fiber-to-the-home networks.

“…Wireless OFDM is included in wireless local access networks (WLANs), ultra wideband (UWB), worldwide interoperability for microwave access (WiMAX) and long term evolution (LTE) standards, among others [5,[9][10][11]. The transmission of OFDM signals in optical fiber communication systems has been appointed for long-haul, metro and access networks [12][13][14][15][16][17].…”

Abstract:The simultaneous transmission of four orthogonal frequencydivision multiplexing (OFDM)-based signals used to provide quintuple-play services along wavelength division multiplexing (WDM) long-reach passive optical networks (LR-PONs) is demonstrated experimentally. Particularly, the transmission performance of custom signal bearing Gigabit Ethernet data, Worldwide Interoperability for Microwave Access, Long Term Evolution and Ultra Wideband (sub-bands 2 and 3) signals is evaluated for different LR-PONs reaches, considering single-wavelength and WDM transmission, and using a centralized impairment compensation technique at the central office that is transparent to the services provided. It is shown that error vector magnitude-compliant levels are obtained for all the OFDM-based signals in WDM LR-PONs reaching 100 km and that negligible inter-channel crosstalk is obtained for a channel spacing of 100 GHz regardless the OFDM-based signal considered. The successful multi-format OFDM transmission along the 100 km-long WDM LR-PON is achieved in the absence of optical dispersion compensation or single sideband modulation, and it is enabled by the performance improvement provided by the centralized impairment compensation realized.

“…Also, radio-over-fiber systems can take advantage of this chirp management as the produced chirp combined with the dispersion the transmission ber in optical access networks can compensate the effects of the optical transmission and, as a result, improve the overall performance of the system [4]. Chirp control measurements obtained with the developed dualdrive modulator are reported in Section 3.…”

A dual-drive LiNbO 3 architecture modulator with chirp management is proposed and developed offering SFDR > 25 dB in a 1.4 V bias excursion compared to only 0.5 V bias excursion in a conventional Mach-Zehnder electro-optical modulator (MZ-EOM). The architecture effectively extends the linear regime and enables the optical transmission of wireless systems employing orthogonal division multiplexing (OFDM) modulation such as ultra-wide band (UWB) which require high linearity over a broad frequency range due to their high peak-to-average power ratio (PARP). Radio-over-fiber UWB transmission in a passive optical network is experimentally demonstrated employing this technique, exhibiting an enhancement of 2.2 dB in EVM after 57 km SSMF when the dual-drive developed modulator is employed.
