By calculating the arc sine (sin -1 ) of 0.56 we determine THE CRITICAL ANGLE = 34º and the ACCEPTANCE ANGLE = 68º.

15 Dispersioni Pulse spreading when propagating through the fibre. Three types of dispersion: Mode-dispersion: Light travelling in different modes undergoes different delays through the fibre. Not present in SM! Material-dispersion (chromatic): Refractive index is function of wavelength Waveguide-dispersion: Propagation of different wavelengths depends on the characteristic of the waveguide, e.g. Index, geometry of core and cladding.
16 Type of Fiber Modes 2.405
17 Chromatic dispersion
18 Pulse spreading Original bits To much spreading results in intersymbol- interference Limits the maximum transmissionrate through the fibre. Difficult to distinguish between bits

20 Source-to-fiber coupling Coupling Efficiency: NA of light source Dimension of light source NA of fiber Fiber core diameter MM fiber coupling: Overfilled: high order mode in the light source will be loss into cladding area Underfilled: all mode available in the source can propagate along the fiber
21 Coupling Light into SM Fiber Coupling into the tiny 10 micrometer core is demandingdi Lining up the light-source is a significant part of the production cost Laser is preferred light-source LED has too large beam

26 Chemical Vapor Deposition (CVD) Chemical Vapor Deposition is chemical reactions which transform gaseous molecules, l called precursor, into a solid material, in the form of thin film or powder, on the surface of a substrate.
27 Chemical Vapor Deposition (CVD) Diffusion Adsorption Decomposition Vaporization of of i Precursor of i Precursor and Molecules Transport and l Incorporation to of to the Precursor Surface into Molecules Solid l Films into Reactor
28 Modified Chemical Vapor Deposition (MCVD) 1. The method was developed by Bell Laboratories. 2. The gaseous mixture of reactants is fed at the end of a rotating silica tube. 3. This tube is heated by a traversing oxygen-hydrogen burner. 4. As a result of chemical reactions glass particles, called soot, are formed and deposited d on internal wall of the tube. 5. The soot is then vitrified by the traversing burner to provide a thin glass layer. 6. The process is repeated many times as the cladding layers and core layers are formed. 7. When the deposition is finished, the temperature of the burner is increased to collapse the tube into a solid preform.
29 Outside Vapor Deposition (OVD) 1. The process was exclusively used by Corning since the 1970s, and the patent of such a technology has expired since July Halogens and O 2 react in a hot flame to form hot glass soot, which is deposited layer by layer on an aluminium oxide or graphite mandrel. 3. The central mandrel is removed after deposition. 5. In the last step, called sintering, a hollow porous preform is dehydrated and collapsed in controlled atmosphere, (e. g. helium) to form desired preform.
30 Vapor-phase phase Axial Deposition 1. In VAD method, the preform can be fabricated continuously. 2. Starting chemicals are carried from the bottom into oxygen-hydrogen y g burner flame to produce glass soot which is deposited on the end of a rotating silica rod. 3. A porous preform is then grown in the axial direction. 4. The starting rod is pulled upward and rotated in the same way as that used to grow single crystals. 5. Finally the preform is dehydrated d d and vitrified in ring heaters. 6. This process is preferred for the mass production.
31 Fiber Drawing 1. The drawing gprocess is integrated with the coating process to avoid contamination of fiber surface. 2. The tip of the perform is heated in a furnace to a molten state. 3. Formed molten gob falls down under the force of gravity while shrinking in diameter into a proper diameter strand. 4 It is controlled contin o sl d ring the 4. It is controlled continuously during the drawing process.
32 Fiber Drawing 5. Fibre diameter drift cannot exceed 0.1%. 6. The strand is threaded through a series coating applicators immediately after drawing. 7. Liquid prepolymer coatings are cured by thermal or ultraviolet apparatus. 8. Dual coating, soft inner and hard outer, is needed to avoid microbending and protect against impact and crushing forces in either manufacturing process or installation. 9. The fiber with coatings is pulled down and wound on a winding drum. 10. The drawing process must take place in air conditioned room, because air pollution influences fiber attenuation.
