This paper proposes and presents the experimental demonstration of 320-Gb/s free-space optical (FSO) communication based on dense-wavelength-division-multiplexing (DWDM) technology and afocal scheme. To the best of our knowledge, this is the first one that adopts DWDM technology and afocal scheme to successfully demonstrate 50-m/320-Gb/s FSO communication. Results show that the free-space transmission distance is greatly increased by the afocal scheme and that the free-space transmission rate is significantly enhanced by the DWDM technology. DWDM FSO communication over a 50-m free-space link with a total transmission rate of 320 Gb/s ð40 Gb/s= Â 8 ¼ 320 Gb/sÞ is achieved. With the aid of a low-noise amplifier and clock/data recovery at the receiving site, good bit-error-rate (BER) performance and clear eye diagram are obtained at a 50-m/320-Gb/s operation. Such 50-m/320-Gb/s DWDM FSO communication provides the advantages of optical wireless communications for long transmission distance and high transmission rate, which is thoroughly useful for long-haul and high-speed light-based WiFi (LiFi) applications.

“…If you cannot watch games and videos on the internet in the dark during night before sleeping on the bed. When the transceivers are equipped with wide beam, the copies of the same signal from different paths reach the [24] destination with different amount of delay, therefore each path has different length from source to destination. This creates a difficulty called multipath distortion which can reason inter symbol interference that unmercifully degrades the performance.…”

Today scenario almost all the peoples are using internet to fulfill their task through a wired or wireless network. The speed of internet is an important issue and everyone be it business, organizations, entrepreneurs, and institutions is thrust for getting correct information at the correct time and correct place. Then need rapid internet connectivity, technology and huge spectrum of channels. The wireless-fidelity (Wi-Fi) gives you the speed of 150 Mbps, according to standards of 1EEE 802.11n, but not sufficient to fulfill the necessity of required users over the network. In order to remove this deficiency of Wi-Fi, a new technology is developed by German physicist, professor Harald Haas is known as Li-Fi. The Li-Fi is a wireless communication system in which light is used as a carrier signal instead of traditional radio frequency as in Wi-Fi. Li-Fi is a technology that utilizes a light emitting diode to transmit data wirelessly. It uses a bidirectional and the wireless mode of communication using light. In this paper, I am aiming to demonstrate a close-up view about Li-Fi Technology. This technology we can obtain the data rate greatly speedier than 10 Mbps, which is a lot greater than our LAN (Local Area Network). Li-Fi is very remunerative over Wi-Fi as it uses VLC by which we can make use of the maximum 60 GHz spectrum. Li-Fi confer transmission of data via LED bulb whose intensity change in an excessively faster speed that it could not be able to be explored by the human eye. Li-Fi is confined to the illuminated area, endue a tremendously controllable environment. The signals cannot travel via walls and are fully secure essentially disassemble the threat of data being hacked remotely.

“…Whereas, mobile backhaul combines reliability and capacity of Ethernet-based optical backhaul with the wide range of coverage and flexibility of Ethernet-based wireless devices. By utilizing the efficacy of both optical fiber and wireless, a fast speed and low cost of service areas can be achieved [21]. It provides cost effectiveness, robustness, flexibility, high capacity, reliability and self-organization compared to fiber or wireless connection alone [22][23][24] Another advantage of having FiWi network is the combination of fiber optic and radio access technologies in multi-tier Radio Access Network (RAN) [2].…”

Fiber-Wireless (FiWi) network is an integration of fiber optic and wireless connections in the same network. It is one of the best solutions to overcome rapid increment of Internet users and bandwidth-hungry services. To facilitate fundamental knowledge and further understanding on FiWi for students and researchers at the university level, this article proposes the development of a fast integration and scalable FiWi router testbed using Raspberry Pis as the embedded system-based hardware for lab-scale experiments. The performance of the router testbed in terms of end-to-end delay and throughput for upstream and downstream are evaluated. The delay values comply with IEEE 802.15.4 routing scheme. The performance of the router testbed is compared with the industrial grade offthe-shelf router in terms of throughput for each network. A testbed stress test is conducted by sending two data traffics simultaneously, and the performance test is repeated for Wireless-Fiber-Wireless and Fiber-Wireless-Fiber network architecture. The results show the proposed router testbed is scalable, flexible, and capable of fast integration.
