Fiber Optic Cable

Copper wire cable and fiber optic cable are two communication media that are widely used in building data communication networks in today’s modern era. For network administrators, choosing the right type of cable to build a network is a must. Air temperature is one of the external factors that can affect the performance of network equipment. This paper provides a comparative analysis of the differences in performance between the use of fiber optic cables and copper wire cables which are capable of transferring data of 1 Gigabit per second. Performance measurement analysis includes the ability to transfer data from both media such as latency, throughput, and packet loss. For testing latency and throughput is done by sending as many as 65,000 data 30 times for each media. Whereas for packet loss testing is done by sending 10,000 data within 1 minute using test bandwidth on the Mikrotik router. From the test results, it can be seen that there is an effect of temperature changes on the performance of copper wire cable and fiber optic cable. The higher the air temperature, the packet loss, and latency will increase. As for the throughput value, the temperature only affects the throughput value on fiber optic cable and does not affect throughput on the copper wire cable.

Optic Communication

This paper deals with data transfer from one computer to another. The serial ports of the computer are used. MAX 232 is used to convert RS 232 logic to TTL logic and then an optical transmitter circuit is used to transmit data via fiber optic cable. The optical transmitter circuit has an LED which is matched with the cable. At the receiver an optical receiver circuit is used which receives data using a photo diode and a MAX 232 again to convert TTL logic to RS 232 for the serial port at the receiving end computer. The desired baud rate can be set. Although the internet can be used, but due to its time consuming nature, one can implement data transfer using wireless medium, though at a relatively high cost. The need, therefore, is felt for fiber optic communication which is cheaper and more suitable for the task. It is cheaper than wireless medium and is prone to lesser loss as compared to wireless medium.

Submarine Cables

Submarine cables represent an invisible yet crucial infrastructure that enable all manner of global communication. Despite their impact, they are seldom a matter of public interest or debate. Further, they are uniquely represented in state, federal, and international legislation. Throughout history, legislative concerns surrounding submarine cables have shifted from colonial monopolies to environmental health and national security. The following document examines the evolution of submarine cables from the first transatlantic copper wire cable to the present fiber-optic cable boom through the legislative lens.

Triple Play Services

AbstractThe current study examines the fiber optic connectivity from Chinese boundary to Rawalpindi and proposes a novel technique for carrying large capacity triple play services across China Pakistan economic corridor (CPEC). With the help of this technique, various wavelength data services can be extended to Pakistan, which can decrease the low bandwidth, poor connectivity and low speed problems of data transfer in Pakistan. This study contributes toward the existing literature in a way that this novel technique of data transmission not only relaxes the laying of fiber optic cable but also reduces the total cost of the project. The proposed technique proposes the deployment of optical frequency comb technique for 820 km CPEC route which could support 4 Tbps data. From the perspective of time energy consumption, the assessment suggests that the laying of fiber optic cable in CPEC is feasible with the existing route at the lowest cost between the two sovereign countries.

The development of telecommunications technology as a communication necessity at this time has been growing rapidly, needed a means of transmission media that is able to distribute information with large capacity and capable data transfer speeds. Implementing using Gigabit Passive Optical Network (GPON) technology, the Fiber to The Home (FTTH) service reaches the user to meet the speed of 2GBps. This study aims to identify the causes of increased attenuation or disturbance in FTTH. The method used in this study is to analyze the attenuation value of each core at the sites studied on the FTTH network at PT Telkom. The total attenuation value of fiber optic cables that are calculated from OLT to ONT must be within the specified reasonable limit of 15-28 dB. The caused of the increase in the attenuation value of fiber optic cables such as the number of splice / connections on each cable, and the occurrence of cable indentations above 45°. To overcome the attenuation value that exceeds the reasonable limit can be done by replacing the fiber cable with attenuation of 0.35dB to fiber cable with attenuation of 0.22 dB, so that the attenuation of the fiber optic cable is at the specified reasonable limit.

Abstract Fiber Optic Network is an advanced and modern system technology, which is used in sending pulses of laser light inside a glass of fiber over long distances, widely used in every environment with various sorts of applications in a different field. It is well-known that the main material of fiber optics is glass, therefore it is typical that the temperature can affect the glass during the thermal expansion. This effect will be applied to the properties of the optical components such as refractive index, radius curvature of the fiber optics layers, and also there is an effect on the data transfer through the fiber optics network units. In this paper, the effect of temperature degree on the optical signal and the functions of the fiber optic network will be simulated, measured, and analyzed. The result will be discussed and the conclusion will show the serious points of thermal effects on the optical signal of a fiber-optic network.

Mobile Ad Hoc

A wireless ad hoc network is a decentralized kind of wireless network. It is a kind of temporary Computer-to-Computer connection. It is a spontaneous network which includes mobile ad-hoc network (MANET), vehicular ad-hoc network (VANET) and Flying ad-hoc network (FANET). Mobile Ad Hoc Network (MANET) is a temporary network that can be dynamically formed to exchange information by wireless nodes or routers which may be mobile. A VANET is a sub form of MANET. It is an technology that uses vehicles as nodes in a network to make a mobile network. FANET is an ad-hoc network of flying nodes. They can fly independently or can be operated distantly. In this research paper Fuzzy based control approaches in wireless network detects & avoids congestion by developing the ad-hoc fuzzy rules as well as membership functions.In this concept, two parameters have been used as: a) Channel load b) The size of queue within intermediate nodes. These parameters constitute the input to Fuzzy logic controller. The output of Fuzzy logic control (sending rate) derives from the conjunction with Fuzzy Rules Base. The parameter used input channel load, queue length which are produce the sending rate output in fuzzy logic. This fuzzy value has been used to compare the MANET, FANET and VANET in terms of the parameters Throughput, packet loss ratio, end to end delay. The simulation results reveal that usage of Qual Net 6.1 simulator has reduced packet-loss in MANET with comparing of VANET and FANET.

Introduction: This article is based on the recent research work in the field of two subjects: signal data parameters in fiber optic communication links, and dispersive properties of optical signals caused by non-homogeneous material phenomena and multimode propagation of optical signals in such kinds of wired links.Purpose: Studying multimode dispersion by analyzing the propagation of guiding optical waves along a fiber optic cable with various refractive index profiles of the inner optical cable (core) relative to the outer cladding, as well as dispersion properties of a fiber optic cable due to inhomogeneous nature of the cladding along the cable, for two types of signal code sequences transmitted via the cable: return-to-zero and non-return-to-zero ones.Methods: Dispersion properties of multimode propagation inside a fiber optic cable are analyzed with an advanced 3D model of optical wave propagation in a given guiding structure. The effects of multimodal dispersion and material dispersion causing the optical signal delay spread along the cable were investigated analytically and numerically.Results: Time dispersion properties were obtained and graphically illustrated for two kinds of fiber optic structures with different refractive index profiles. The dispersion was caused by multimode (e.g. multi-ray) propagation and by the inhomogeneous nature of the material along the cable. Their effect on the capacity and spectral efficiency of a data signal stream passing through such a guiding optical structure is illustrated for arbitrary refractive indices of the inner (core) and outer (cladding) elements of the optical cable. A new methodology is introduced for finding and evaluating the effects of time dispersion of optical signals propagating in fiber optic structures of various kinds. An algorithm is proposed for estimating the spectral efficiency loss measured in bits per second per Hertz per each kilometer along the cable, for arbitrary presentation of the code signals in the data stream, non-return-to zero or return-to-zero ones. All practical tests are illustrated by MATLAB utility.
