“…Thus, the faithful fiber distance with a 12.5% EVM limit (for 16-QAM) is 100km (at 1596nm) and 120km (at 1527nm) with 2D-SWZCC code. This is because 2D-SWZCC code required lower bandwidth and zero-cross correlation permits cardinality with single weight which will enhance the system capacity [13]. Also, Fig.…”

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.

“…The clear scatterplot is obtained from 2.5 to 15Gbps and 2.5 to 20Gbps for the downlink and uplink channels respectively at the BER limit of 3.8×10 -3 , which is undistorted and well detected, signifying little deterioration because of the transmission of fiber considering real environment conditions. This is also because of increase in bandwidth spectrum due to increase in data rate and thus proposed system can attain 15Gbps (for D/S) and 20Gbps (for U/S) for four users [13,59]. Tables 9 as well as 10 depict the comparisons of the proposed system with respect to (w.r.t.)…”

“…From the comprehensive study, it is noticed that the prior researchers mostly focused on individual TWDM-PON and OFDM modulation methods for the communication systems. In these works, except a couple of [13,33], researchers don't consider OFDM and TWDM-PON using two-dimension (2D) spectral/special (S/S) SWZCC code for NG-PON2 based systems. In short, the hybrid TWDM-OFDM PON system using 2D-SWZCC code is a superb system as it has the potential to transfer high-speed continuous coded information signals considering fiber non-linearities and impairments.…”
