Deducing of Optical and Electronic Domains Based Distortions in Radio over Fiber Network

Abstract

Managing the users multimedia and long-range based demands, the radio over fiber (RoF) mechanism has been introduced recently. RoF mingles the optical and radio communication frameworks to increase mobility and offer high capacity communication networks (CNs). In this paper, a full-duplex RoF-based CN is investigated for the next-generation passive optical network (PON), utilizing wavelength division multiplexing (WDM) technology. The desolations on account of optical and electronic domains (OEDs) are addressed, using dispersion compensation fiber (DCF) and optical and electrical filters, including modulation scheme. The analytical and simulation models are analyzed in terms of phase error (PE), radio frequency (RF), fiber length and input and received powers. The performance of the proposed model is successfully evaluated for 50 km range, −40 to −18 dBm received power, −20 to 0 dBm input power, where below 10−6 bit error rate (BER) is recorded. Thus, this signifies that the presented model exhibits smooth execution against OEDs impairments.

Integrated Free-Space Optics and Fiber Optic Network Performance Enhancement for Sustaining 5G High Capacity Communications

“…However, the throughput, reliability, and latency requirements will have to meet increasingly demanding criteria due to these new uses. Due to recent advancements in sub-terahertz (sub-THz) technology, researchers are pushing the 5G new radio (NR) to a higher band, particularly the sub-THz spectrum stretching between 100 to 300 GHz, as mentioned in Figure 1 [1][2][3]. 5G NR connection in the sub-THz band is gaining popularity due to its high data rates.…”

Free Space Optics Transmission Performance Enhancement for Sustaining 5G High Capacity Data Services

“…Recent developments in online marketing have enhanced the value of free space optics (FSO), purposing to improve the capacity and transmission accuracy of communication systems [1]. Low cost installation, improved security, and colossal bandwidth are the critical properties of FSO; therefore, communication system FSO based design is widely used in terrestrial and deep space applications [2]. The main structure of FSO is linked with the setup of an optical network; it takes inputs from laser based transmitters and is received at the photodiode based receiver [3].…”
