This document presents information on optical fiber communication. It discusses the basic elements of an optical fiber including the glass core and cladding. It also describes fiber-optic communication as transmitting information using pulses of light through optical fibers. Finally, it classifies optical fibers as either single mode or multi-mode fibers and lists some common types as well as sources of loss in optical fiber communication systems.

2. An optical fiber is a flexible, transparent fiber made by drawing glass (silica) or
plastic to a diameter slightly thicker than that of a human hair.
Optical Fiber
Elements of optical fiber
 Glass core
 Glass cladding
 Primary buffer
 Secondary buffer

3. FiberOpticCommunication
Fiber-optic communication is a method of transmitting information from one
place to another by sending pulses of light through an optical fiber.

4. ClassificationofOpticalFiber
Single Mode Fiber:
In fiber-optic communication, a single-mode optical fiber is an optical fiber
designed to carry light only directly down the fiber - the transverse mode.
Types of Single Mode fiber:
 Non dispersion-shifted fiber (NDSF)
 Dispersion-Shifted Fibers (DSF)
 Non-Zero-Dispersion-shifted fibers (NZ-DSF)

5. ClassificationofOpticalFiber
Multi-Mode Fiber:
Multi-mode optical fiber is a type of optical fiber mostly used for
communication over short distances, such as within a building or on a campus.
Types of Multi-Mode fiber:
 Step-Index Multimode Fiber
 Graded-Index Multimode Fiber

6. LossesofOpticalFiberCommunication
 Intrinsic Fiber CoreAttenuation
 Light absorption
 Scattering
 Bending loss
 Coupling loss
