  • 19:0319:03, 2 May 2024 diff hist +1,704 Optical fiberRe-written this section to present the most updated, correct, and relevant to optical fibers description of light scattering and resulting signal attenuation in optical fibers. Described the most advanced approaches towards reducing Rayleigh scattering, which are used to manufacture ultra low loss optical fibers, including those for submarine telecom cables.

  • 17:1017:10, 2 May 2024 diff hist −57 Optical fiberPicture describing light scattering on surfaces were removed as not relevant to optical fiber subject. New picture showing angular and wavelength dependence of Rayleigh scattering was added to describe the the dominant type of light scattering in optical fibers. Tags: Manual revert Visual edit

  • 16:5816:58, 2 May 2024 diff hist −11 Optical fiberTwo pictures describing light scattering on surfaces were removed as not relevant to optical fiber subject. New picture showing angular and wavelength dependence of Rayleigh scattering was added to describe the the dominant type of light scattering in optical fibers. Tag: Visual edit
  • 15:4515:45, 2 May 2024 diff hist +345 Optical fiberCorrected and better defined the origin of light scattering loss in optical fibers. Tag: Visual edit

  • 14:3214:32, 2 May 2024 diff hist +806 Optical fiberAdded a more detailed and meaningful description of the dominant attenuation mechanisms, and the values of attenuation components in optical fibers. Tag: Visual edit
  • 13:4913:49, 2 May 2024 diff hist −517 Optical fiberThe reference to attenuation at the depth of Mariana Trench was removed because it is redundant to attenuation in a 10 km fiber. The reference to National Association of Broadcasters Engineering Handbook (10th ed.). Taylor & Francis. pp. 1667–1685 was removed because it is a large and old book, mostly pre- optical fiber era, and the only relevant reference to Mariana Trench was removed. Tag: Visual edit
  • 02:5302:53, 2 May 2024 diff hist +417 Optical fiberRemoved the picture which was outdated an incorrect. Silica theoretical minimum attenuation curve was higher that the actual experimentally measured attenuation in silica core optical fiber (it showed 0.2 dB/km lowest point and 1 dB/km at 1000 nm, while the experimentally measured low point is 0.14 dB/km and 0.7 dB/km at 1000 nm). Their theoretical minimum attenuation curve for ZBLAN is on the other hand more than 2 orders of magnitude lower than the experimentally measured minimum. Tag: Visual edit
