  19. 20. What is Zero Water Peak Fiber <ul><li>Zero Water Peak fibers are single-mode fibers in which the stray Hydrogen atoms (water) are reduced significantly or eleminated, which improves signal loss’, this frees up more wavelengths for high quality transmission (Fig. 5). These fibers allow 50% more channels by opening up the wavelength range around 1240 - 1400 nm, previously unavailable for transmission. </li></ul>

  21. 22. Characteristic Impedance (Ohms): <ul><li>Characteristic Impedance (Ohms): A value based on the inherent conductance, resistance, capacitance and inductance of a cable that represents the impedance of an infinitely long cable. When the cable is out to any length and terminated with this Characteristic Impedance, measurements of the cable will be identical to values obtained from the infinite length cable. That is to say that the termination of the cable with this impedance gives the cable the appearance of being infinitely long, allowing no reflections of the transmitted signal. If termination is required in a system, the termination impedance value should match the Characteristic Impedance of the cable. If not, the extra signal will reflect back up the line, causing interference (Bit Errors). </li></ul>

  23. 24. Drawing <ul><li>The fiber is drawn from the preform and then coated with a protective coating </li></ul>
  24. 25. Index of Refraction <ul><li>When light enters a dense medium like glass or water, it slows down </li></ul><ul><li>The index of refraction (n) is the ratio of the speed of light in vacuum to the speed of light in the medium </li></ul><ul><li>Water has n = 1.3 </li></ul><ul><ul><li>Light takes 30% longer to travel through it </li></ul></ul><ul><li>Fiber optic glass has n = 1.5 </li></ul><ul><ul><li>Light takes 50% longer to travel through it </li></ul></ul>
  25. 26. Attenuation and Dispersion <ul><li>See animation at link Ch 2e </li></ul>
  26. 27. Cable impedance What is the cable impedance and when it is needed? The basic idea is that a conductor at RF frequencies no longer behaves like a regular old wire. As the length of the conductor (wire) approaches about 1/10 the wavelength of the signal it is carrying - good ol' fashioned circuit analysis rules don't apply anymore. This is the point where things like cable impedance and transmission line theory enter the picture. The key tenet of all transmission line theory is that the source impedance must be equal to the load impedance in order to achieve maximum power transfer and minimum signal reflection at the destination. In real world case this generally means that the source impedance is the same as cable impedance and the value of the receiver in another end of the cable has also the same impedance.
  27. 28. Three Types of Dispersion <ul><li>Dispersion is the spreading out of a light pulse as it travels through the fiber </li></ul><ul><li>Three types: </li></ul><ul><ul><li>Modal Dispersion </li></ul></ul><ul><ul><li>Chromatic Dispersion </li></ul></ul><ul><ul><li>Polarization Mode Dispersion (PMD) </li></ul></ul>
  28. 29. Modal Dispersion <ul><li>Modal Dispersion </li></ul><ul><ul><li>Spreading of a pulse because different modes (paths) through the fiber take different times </li></ul></ul><ul><ul><li>Only happens in multimode fiber </li></ul></ul><ul><ul><li>Reduced, but not eliminated, with graded-index fiber </li></ul></ul>
  29. 30. Modal Distribution <ul><li>In graded-index fiber, the off-axis modes go a longer distance than the axial mode, but they travel faster, compensating for dispersion </li></ul><ul><ul><li>But because the off-axis modes travel further, they suffer more attenuation </li></ul></ul>
  30. 31. Chromatic Dispersion <ul><li>Different wavelengths travel at different speeds through the fiber </li></ul><ul><li>This spreads a pulse in an effect named chromatic dispersion </li></ul><ul><li>Chromatic dispersion occurs in both singlemode and multimode fiber </li></ul><ul><ul><li>Larger effect with LEDs than with lasers </li></ul></ul><ul><ul><li>A far smaller effect than modal dispersion </li></ul></ul>
  31. 32. Polarization Mode Dispersion <ul><li>Light with different polarization can travel at different speeds, if the fiber is not perfectly symmetric at the atomic level </li></ul><ul><li>This could come from imperfect circular geometry or stress on the cable, and there is no easy way to correct it </li></ul><ul><li>It can affect both singlemode and multimode fiber. </li></ul>
  32. 33. Equilibrium Modal Distribution <ul><li>A long fiber that has lost the high-order modes is said to have an equilibrium modal distribution </li></ul><ul><li>For testing fibers, devices can be used to condition the modal distribution so measurements will be accurate </li></ul>
  33. 34. Optical Loss in dB (decibels) <ul><li>If the data link is perfect, and loses no power </li></ul><ul><ul><li>The loss is 0 dB </li></ul></ul><ul><li>If the data link loses 50% of the power </li></ul><ul><ul><li>The loss is 3 dB, or a change of – 3 dB </li></ul></ul><ul><li>If the data link loses 90% of the power </li></ul><ul><ul><li>The loss is 10 dB, or a change of – 10 dB </li></ul></ul><ul><li>If the data link loses 99% of the power </li></ul><ul><ul><li>The loss is 20 dB, or a change of – 20 dB </li></ul></ul><ul><li>dB = 10 log (Power Out / Power In) </li></ul>Data Link Power In Power Out
