Optical amplifier

Hence, in this project, I used a fiber optic based optical sensor, based on intensity, as well as wavelength. I developed a complete integrated system by using this optical sensor in the detection of petroleum leakages in pipelines, which is a user-friendly, cost-effective solution and allows an easy setup of the parameter. CE 2.3 The aim of the proposed project is to design and fabricate a petroleum detection system by using optical fiber sensor, detection system and microcontroller. CE 2

Application of Sensor in Petroleum Industry INTRODUCTION Sensor is an electronic device that detects a change in physical stimulus and turns it into a signal which can be measured or recorded. There are various sensors such as flows sensor, temperature sensor, pressure sensor and so forth. Each type of sensors has their own characteristics. Petroleum industry utilized many types of sensor, some of that are temperature sensor, pressure sensor, liquid level sensor and liquid leakage sensor

optically or electronically. In optical communication, there are two broadly used techniques for increasing the capacity of the transmission. The first technique is to spread-out the bandwidth by adding numerous optical carriers. This technique has already been slow and deployed and it is known as Wavelength Division Multiplexing (WDM). Wavelength Division Multiplexing can benefit to extend the transmission bandwidth by adding various transceivers for the current optical fiber links deprived of the need

Malaysia as an insulator known as gutta percha resin. In 1956, the first telephone cable was laid, and in 1988, the first fiber optic cable. Today, SCC are made up of pure glass fibers that allow light to transmit using internal reflection. These optical fibers are

but the application of fiber optics in telephony was made possible. In 1987, an additional accomplishment in the fiber optics industry was fulfilled; this accomplishment was the erbium-doped fiber amplifier, which admitted numerous channels of light to coexist on a single circuit. This fiber amplifier rendered sufficient channels for single fiber cable to manage 80 million telephone calls at the same time (Greatest Achievements, 2000). Nowadays, fiber optic technology carries data by distributing

forms one plate. Sound pressure moves one of its plates. The movement of the plate changes the capacitance. The electrets capacitor is connected to an FET amplifier. These microphones are small, have excellent sensitivity, a wide frequency response and a very low cost. First amplification stage: This is a standard self biasing common emitter amplifier. The 22nF capacitor isolates the microphone from the base voltage of the transistor and only allows alternating current (AC) signals to pass. The tank

Copper Cable (Ethernet) versus fiber optics The topic we picked to do our presentation on is fiber optics versus cable, which is better for a company use and what are the future prospects of fiber optics and cable. We also talked about the history of DSL, broadband, fiber optics, and dial-up. There are both pros and cons with fiber optics and copper cable. The main point for our research is which would companies choose. During our research there was many obstacles because it was hard to say why

cable with Amphenol RJF connectors. The maximum cable run using flexible reel-mounted Cat5 cable is 100m, but possible to get it run 130m with permanent installation Cat7 cable. Another optional connection is using Fiber Optic cable but the Fiber Optical interface card need to install separately. The Local rack place at the same place with control surface and inside it is 2 Digital Signal Processing engine - Studer Score Live technology, with only 2 DSP cards will be capable of 64 inputs with 40-bit

Laboratory Report By Akash Sherchan Student I.D. #: 1124433 University of Warwick Summary The strain gauge laboratory session had a lot of aims and one of the main aims was to provide us with experience in using circuits based on operational amplifiers and examine the characteristics of these circuits when they amplify DC signals. Another aim was to also investigate the use and characteristics of resistive strain gauges. The overall objective was to understand the how these widely used transducers
