“…By 2022, it's projected that traffic between machines and connected devices would increase globally at a compound annual growth rate of 47% [15] [16]. By 2023, Cisco predicts that 50 billion people using fixed-line, mobile, and machine-to-machine internet will need between 44 and 110 Mbps of bandwidth per user to access modern applications [17] [18].…”

In this article, the performance of a fixed grid network is examined for various modulation formats to estimate the system's capacity and spectral efficiency. The optical In-phase Quadrature Modulator (IQM) structure is used to build a fixed grid network modulation, and the homodyne detection approach is used for the receiver. Data multiplexing is accomplished using the Polarization Division Multiplexed (PDM) technology. 100 Gbps, 150 Gbps, and 200 Gbps data rates are transmitted under these circumstances utilizing various modulation formats. Various pre-processing and signal recovery steps are explained by using modern digital signal processing systems. The achieved spectrum efficiencies for PM-QPSK, PM-8 QAM, and PM-16 QAM, respectively, were 2, 3, and 4 (bits/s)/Hz. Different modulation like PM-QPSK, PM-8-QAM, and PM-16-QAM each has system capacities of 8-9, 12-13.5, and 16-18 Tbps and it reaches transmission distances of 3000, 1300, and 700 kilometers with acceptable Bit Error Rate (BER≤ 2× 10-3 ) respectively. Peak optical power for received signal detection and full width at half maximum is noted for the different modulations under a fixed grind network.

In this paper, a hybrid time and wavelength division multiplexing passive optical network (TWDM‐PON) and wavelength division multiplexing optical code division multiple access (WDM‐OCDMA) with free space optics (FSO) for bidirectional 160/40 Gbps transmission has been proposed. Also, to offer the information to 64 users over 60 km fiber and 600 m FSO channels under diverse climate conditions have been presented. Also, to resist the fiber impairments, interference, noise and losses under the effect of unfavorable climate conditions in hybrid fiber‐FSO link, a modified new zero‐cross correlation (NZCC) code is effectively used in the system to enhance the system ability to access shared bandwidth with users' security. The performance of the designed PON system has been analysed and investigated for diverse FSO (10–600 m) and fiber distance (0–60 km) under distinct climate conditions. Based on mathematical and simulation analysis, the designed system using modified NZCC code is shown to provide better performance than other OCDMA codes. The designed system with hybrid fiber‐FSO link improves the performance of the system in terms of high received optical power of 3 dBm and support 110 users simultaneously at acceptable BER of 10−9, under fiber impairments, climate conditions and turbulences. Additionally, on comparing the designed system's performance with the prior latest work in literature reveals its superiority than others in codes and system design.

Intelligent transportation is becoming integral part of future smart cities where driverless operations may provide hassle free conveyance. Photonic radar technology is one such contender to deliver attractive applications in autonomous vehicle sector. In this paper we have discussed the basic principle of frequency modulated continuous wave (FMCW) photonic radar and their possible advantages. Further the basic detection schemes that is direct detection and coherent detection is explained mathematically as well as numerical simulations to understand workings is also carried out. The obtained results concludes that direct detection scheme provides minimal complexity in its architecture and is sensitive to received signal strength at the cost of thermal noise and poor sensitivity. On the other hand, coherent detection offers higher target range estimation as well as velocity measurement at the expense of increased system complexity.
