On the basis of refractive index There are two type of optical fiber:- 1) Step index optical fiber 2) Graded- index optical fiber. 11. Single Index fiber:- Step-index optical fiber-the refractive index of core and cladding are constant. The light ray propagate through it in the form of meridiognal rays which cross the fiber axis during every. 1 Lecture 5: Optical fibers Optical fiber basics Linearly polarized modes Field analysis/wave equation of weakly guiding fibers Attenuation in fibers Dispersion in fibers References: Photonic Devices, Jia-Ming Liu, Chapter 3 *Most of the lecture materials here are adopted from ELEC342 notes.
What is Optical Fiber? Guide to 6 Different Types of Optical Fiber
An optical fiber is a cylindrical dielectric waveguide made of low-loss materials such as silica glass. It has a central core in which the light is guided, embedded in an outer cladding of slightly lower refractive index (Fig. 8.0-l). Light rays incident on the core-cladding boundary at angles greater than the critical angle undergo total. • Coax - 36kg or 80lb per 1000 ft. • Fiber optic cables are substantially lighter in weight and occupy much less volume than copper cables with the same information capacity. • Fiber optic cables are being used to relieve congested underground ducts in metropolitan and suburban areas. Silver or Gold coated core of a polymer or glass clad fibre. Metal deposition ( e.g., using vapor deposition techniques). Use of suitable lithographic techniques, to fabricate periodic optical fibre structures such as Long-period Fibre Gratings (LPFG) or Long period Waveguide Gratings (LPWG). 3. INTRODUCTION Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic carrier wave that is modulated to carry information. Optical Fibre - An optical fibre is a dielectric wave guide that operates at optical frequencies.

Engineering. An optical fiber (or optical fibre) is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair.Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications. T F Optical communication uses infrared light. C band is used commonly because of EDFAs. Graded index fiber has a lower modal dispersion than step index fiber Plastic fiber is cheaper than glass fibers Dispersion shifted fiber is used in DWDM systems If a signal can travel 1600 km at 10 Gbps, due to PMD it can travel 400 km at 40 Gbps Fiber. An optical fiber consists of three basic concentric elements: the core, the cladding, and the outer coating (Figure 1). The core is usually made of glass or plastic, although other materials are sometimes used, depending on the transmission spectrum desired. The core is the light-transmitting portion of the fiber.

43. Optical Fiber Losses Types of Attenuation Absorption Loss: Caused by the fiber itself or by impurities in the fiber, such as water and metals. Scattering Loss: Intrinsic loss mechanism caused by the interaction of photons with the glass itself. Bending loss: Loss induced by physical stress on the fiber. 44. Based on Rayleigh backscattered light in an optical fiber (single mode or multi mode) It senses all points along the fiber and monitors acoustic perturbations to the fiber Specifications Frequency range - 1mHz to 100kHz Spatial resolution - 1 m Length - 50 km Strong applications Oil and gas - seismic Pipeline monitoring

8. 8 Continued… Each fiber can carry many independent channels, each using a different wavelength of light. As of 2011 the record for bandwidth on a single core was 101 Tbit/sec (370 channels at 273 Gbit/sec each). The record for a multi-core fibre as of January 2013 was 1.05 petabits per second.
