“…From Table 3 it is clear that as compared to previous work in Memon and colleagues, [5][6][7][8][9] the proposed work shows better performance than others in terms of type of OCDMA code, maximum data rate and distance with acceptable log(BER) of −9. Besides this, the proposed work offers advantages of cost-effectiveness, easy upgradeability, scalability and reliability by supporting more than 250 simultaneous users.…”

In this paper, a bidirectional symmetric 16 × 10 Gbps next generation passive optical network stage 2 (NG-PON2) based time and wavelength division multiplexing PON (TWDM-PON) has been designed. To satisfy the requirement for ever-increasing demands for high-security, high speed and long-reach with high system capacity to handle the large number of users, two-dimensional spectral/spatial single weight zero-cross correlation code has been employed in TWDM-PON. The results show that the proposed design can handle simultaneous users of 240 in downstream and 250 in upstream channels over 10 km transmission distance at symmetric 1.6 Tbps data rate. The transmission distance can be extended upto downlink 110 km and uplink 170 km, delivering receiver sensitivity of −45 and −46 dBm, respectively. Also, high optical signal to noise ratio of 62 dB in downlink and 72 dB in uplink is successfully achieved.Meanwhile, the proposed work is superior to the recent work.

In this study, the hybrid unipolar-bipolar (U-B) optical code division multiple access (OCDMA) with mixed unipolar-bipolar scheme in free-space optical communication was proposed. Additionally, the codeword assigned introduced the quasi-polarized code, which could be used to transmit both the unipolar and bipolar section. Using OptiSystem simulations, the model was studied. According to the results from the simulation, the proposed hybrid U-B OCDMA can correctly decode the original optical signal from its matching encoder. Further testing of the hybrid U-B OCDMA system was conducted in turbulence conditions. According to the simulation results, walsh-zero cross correlation (ZCC) performs better than all other codes for the unipolar segment whereas walsh-hadamard (W-H) code performs best for the bipolar section. The simulations also showed that the performance deterioration of the walsh-ZCC algorithm was the greatest.

The optical communications have been the backbone of the most dramatic developments in telecommunications systems in the past two decades, so that the current world of communications is unthinkable without the infrastructure of ber optic networks. Also, the speed and bandwidth of optical devices have expanded the development of optical telecommunication systems, so the design, simulation and fabrication of optical devices have become more and more respected by researchers in this eld. In this paper, a design for optical narrow Band Pass Filter (BPF) using two-dimensional (2D) photonic crystals (PCs) is presented that are suitable for applications in optical ber communications (third window) in Wavelength-Division Multiplexing (WDM) systems. BPF was simulated by a two-dimensional timing method (FDTD) Finite-difference time-domain (FDTD). Also, the plane-wave expansion (PWE) method was used to evaluate the bands and calculate the Photonic Band Gap. Simulation results show this desired structure, acts as a very sharp optical BPF in the central wavelength of 1550 nm (In order to minimize attenuation). Normal voltage transmission e ciency, full width at half maximum (FWHM), and Focal Plane Module (FPM) for proposed BPF were 94.8%, 2583 and 0.6 nm, respectively.
