“…Yufeng Shao proposed experimentally a 16QAM-OFDM radio over fiber (RoF) system utilizing superior over Nyquist pulse shaping (BTN-PS) and discrete multi-tone (DMT) modulation technique to lessen the peak-to-average power ratio (PAPR) as well as to strengthen the RS. The results demonstrated that the proposed system offers a faithful 42km and 0.4m over fiber and wireless channel respectively at a 5Gbps D/S data rate [14]. Cheng Ju et al introduced an OFDM-PON U/S system based on various modulation format conversion schemes.…”

The hybrid time and wavelength division multiplexing passive optical network (TWDM-PON) with a 1:128 split ratio and 16- quadrature amplitude modulation orthogonal frequency division multiplexing (QAM-OFDM) modulation system using optical code division multiple access (OCDMA) code results in high transmission security, channel capacity and robustness against interference. Thus in this paper, a bidirectional symmetric 1.6 Tbps hybrid TWDM-OFDM PON system using two-dimensional spectral/spatial-single weight zero cross-correlation (2D-S/S SWZCC) code supporting a large number of users for long-reach as well as high-speed applications has been proposed and analysed considering fiber impairments and noise. Numerically calculated receiver sensitivity (RS) and splitter power budget (SPB) are -36dBm and 23dB for downstream as well as RS and SPB for upstream transmission of -33dBm and 10dB respectively showing the supremacy of using 2D-S/S SWZCC code in the system than other OCDMA codes. Also, the simulation results show that the proposed system using 2D-SS SWZCC code provides a faithful 120km transmission distance as well as a high transmission rate of 16×15/20Gbps with a maximum received power of -32.8dBm supporting more than 190 simultaneous users. The designed PON system offers the best performance over other conventional PONs. The number of users can be increased up to 250 with an optical signal-to-noise ratio of 110 dB and -30 dBm received power.

“…However, high peak-to-average power ratio (PAPR) not only increases complexity of digital-to-analogue (D/A) and analogueto-digital (A/D) converters, but also causes signals nonlinear distortion since it makes the power amplifier (PA) work in a non-linear area in optical access systems [2][3][4][5][6][7][8]. Hence, OFDM signals with low PAPR are desirable for optical signals access.…”

Background: Orthogonal frequency division multiplexing has been regarded as one of the promising technologies for the optical access systems application. However, high peak-to-average power ratio will cause the signal distortion and enable the used amplifier to operate in nonlinear section. Methods: In this paper, a modified selected mapping technique is introduced for reducing the peak-to-average power ratio and enhancing reception performance of the downstream 8QAM-OFDM signals in optical access systems. Results: Compared with the traditional selected mapping technique, the PAPR value of 8QAM-OFDM optical downstream signals with 128 subcarriers is reduced by almost 2 dB using modified SLM when the complementary cumulative distribution function probability value is 10−2. Moreover, the bit error rate performance will be improved, while 10Gbit/s 8QAM-OFDM optical downlink signals are transmitted over single mode fiber with different access length. Conclusions: Hence, the proposed scheme becomes more efficient for the future optical orthogonal frequency division multiplexing access systems.

“…At present, with the rapid increase of the types and number of broadband communication access services, the development trend of optical access system is mainly focused on high frequency band utilization and user bandwidth [1]- [4]. Orthogonal frequency division multiplexing (OFDM) optical access technology as a multi-carrier modulation technology has received more and more researcher's attention [5] [6]. The reason is that it has a good ability to resist chromatic dispersion (CD) and polarization mode dispersion (PMD), and the spectrum utilization rate is high and the flexible multi-service bandwidth allocation can be realized by using a large number of sub carriers [7] [8].…”

In this paper, the downstream transmission performance of two types of 8QAM-OFDM optical signals in broadband optical access system has been analyzed. After modulation and coding, two types of 10 Gbit/s 8QAM-OFDM optical access signals are downstream transmitted over 1 km, 10 km, 20 km and 40 km single mode fibers (SMFs) and received successfully. Different transmission distances impact on the bit error rate (BER) of the received signal is analyzed by simulation, while the signal to noise ratio (SNR) is 20 dB. The results show that, while the transmission distance is shorter than 10 km, the BER values of two types of 8QAM-OFDM optical signals are smaller than 10 −10. As the above optical access signals are transmitted over 40 km SMF, the BER value of the first type of 8QAM-OFDM signals is bigger than 10 −6 , and the BER of the other type of 8QAM-OFDM signals is smaller than 10 −6 .
