Fiber Optic Training Courses provide a comprehensive understanding of Fiber Optic Cabling. Suited to anyone working with optical fiber at any level, the online course covers fiber optic infrastructure transmission, construction, planning, installation, termination, inspection, testing and moreFiber optics, or optical fibers, are long, thin strands of carefully drawn glass about the diameter of a human hair. These strands are arranged in bundles called optical cables. … So, the optical fiber transmits “data” by light to a receiving end, where the light signal is decoded as data.The three basic elements of a fiber optic cable are the core, the cladding and the coating. Core: This is the light transmission area of the fiber, either glass or plastic. The larger the core, the more light that will be transmitted into the fiber.The optical fibre is a device which works on the principle of total internal reflection by which light signals can be transmitted from one place to another with a negligible loss of energy. Characteristics of Optical Fibre: It has a large bandwidth.Optical fibres works on the principle of total internal reflection. When light ray strikes at the internal surface of optical fibre cable called such that incidence angle is greater than critical angle, then incident light ray reflects in the same medium and this phenomenon repeats.Fiber optic cables have a much greater bandwidth than metal cables. The amount of information that can be transmitted per unit time of fiber over other transmission media is its most significant advantage. An optical fiber offers low power loss, which allows for longer transmission distancesFiber optic cables have a much greater bandwidth than metal cables. The amount of information that can be transmitted per unit time of fiber over other transmission media is its most significant advantage. An optical fiber offers low power loss, which allows for longer transmission distancesThere are three types of fiber optic cable commonly used: single mode, multimode and plastic optical fiber (POF). Transparent glass or plastic fibers which allow light to be guided from one end to the other with minimal lossFor fiber optics with glass fibers, we use light in the infrared region which has wavelengths longer than visible light, typically around 850, 1300 and 1550 nm. Why do we use the infrared? Because the attenuation of the fiber is much less at those wavelengths.The most important properties for communications are attenuation, light collection and propagation, fiber dispersion, and mechanical strength. Nonlinear effects can be important in some cases, particularly for sensing and high-performance systems

The high ways of the IT society are the optical fibres. An optical fibre can transport several terabit per second over thousands of kilometers. The limitations today are in the electronics. Fibre-optic communication is an established technique but is simultaneously in rapid technical development towards higher bit-rates and more complex networks. The course will give you the knowledge in order to understand both the fundamentals and the rapid development, that you as professional engineer can use the fibre optics efficiently. The course treats important devices as optical fibres, laser diodes, optical detectors, and receivers from physical and transmission system point of view. You will also learn how to optimise optical communication links and calculate the bit error rate.he course content is knowledge of fibre-optical components and systems with applications to communications. The transmission systems relevant parameters of devices are derived from physical descriptions, and form the basis for designing fibre-optic links. After a completed course, the participants should be able to:- understand, describe, analyse, and compare the most important devices: optical fibres, light sources, and optical detectors- design of digital fibre-optic linksThe contents of the course book are comprehensive. Most chapters start at a rather elementary level but end at a rather advanced level. Some parts in the book are near the research front and are more suitable for advanced courses. The focus of the course is defined by the lectures and the problems in the supplementary course material. Some parts of the book are not included or only briefly discussedOptical fiber is the technology associated with data transmission using light pulses travelling along with a long fiber which is usually made of plastic or glass. Metal wires are preferred for transmission in optical fiber communication as signals travel with fewer damages. Optical fibers are also unaffected by electromagnetic interference. The fiber optical cable uses the application of total internal reflection of light. The fibers are designed such that they facilitate the propagation of light along with the optical fiber depending on the requirement of power and distance of transmission. Single-mode fiber is used for long-distance transmission, while multimode fiber is used for shorter distances. The outer cladding of these fibers needs better protection than metal wiresThe types of optical fibers depend on the refractive index, materials used, and mode of propagation of light.

The classification based on the refractive index is as follows:

Step Index Fibers: It consists of a core surrounded by the cladding, which has a single uniform index of refraction.Graded Index Fibers: The refractive index of the optical fiber decreases as the radial distance from the fiber axis increases.The classification based on the materials used is as follows:

Plastic Optical Fibers: The polymethylmethacrylate is used as a core material for the transmission of the light.Glass Fibers: It consists of extremely fine glass fibers.The classification based on the mode of propagation of light is as follows:

Single-Mode Fibers: These fibers are used for long-distance transmission of signals.Multimode Fibers: These fibers are used for short-distance transmission of signals.The mode of propagation and refractive index of the core is used to form four combination types of optic fibers as follows:

Step index-single mode fibersGraded index-Single mode fibersStep index-Multimode fibersGraded index-Multimode fibershe optical fiber works on the principle of total internal reflection. Light rays can be used to transmit a huge amount of data, but there is a problem here – the light rays travel in straight lines. So unless we have a long straight wire without any bends at all, harnessing this advantage will be very tedious. Instead, the optical cables are designed such that they bend all the light rays’ inwards (using TIR). Light rays travel continuously, bouncing off the optical fiber walls and transmitting end to end data. Although light signals do degrade over progressing distances, depending on the purity of the material used, the loss is much less compared to using metal cables. A Fibre Optic Relay System consists of the following components:

The Transmitter – It produces the light signals and encodes them to fit to transmit.The Optical Fibre – The medium for transmitting the light pulse (signal).The Optical Receiver – It receives the transmitted light pulse (signal) and decodes them to be fit to use.The Optical Regenerator – Necessary for long-distance data transmission.Course Outline:
