  2. Single-mode optical fiber - Wikipedia

    en.wikipedia.org/wiki/Single-mode_optical_fiber

    Single-mode fibers are therefore better at retaining the fidelity of each light pulse over longer distances than multi-mode fibers. For these reasons, single-mode fibers can have a higher bandwidth than multi-mode fibers. Equipment for single-mode fiber is more expensive than equipment for multi-mode optical fiber, but the single-mode fiber ...

  3. Multi-mode optical fiber - Wikipedia

    en.wikipedia.org/wiki/Multi-mode_optical_fiber

    The equipment used for communications over multi-mode optical fiber is less expensive than that for single-mode optical fiber. [1] Typical transmission speed and distance limits are 100 Mbit/s for distances up to 2 km ( 100BASE-FX ), 1 Gbit/s up to 1000 m, and 10 Gbit/s up to 550 m.

  4. Modal dispersion - Wikipedia

    en.wikipedia.org/wiki/Modal_dispersion

    A special case of modal dispersion is polarization mode dispersion (PMD), a fiber dispersion phenomenon usually associated with single-mode fibers. PMD results when two modes that normally travel at the same speed due to fiber core geometric and stress symmetry (for example, two orthogonal polarizations in a waveguide of circular or square ...

  5. Optical fiber - Wikipedia

    en.wikipedia.org/wiki/Optical_fiber

    The most common type of single-mode fiber has a core diameter of 8–10 micrometers and is designed for use in the near infrared. Multi-mode fiber, by comparison, is manufactured with core diameters as small as 50 micrometers and as large as hundreds of micrometers.

  6. Mode scrambler - Wikipedia

    en.wikipedia.org/wiki/Mode_scrambler

    When the telecom industry converted to near-exclusive use of single-mode fiber ca. 1984, multimode fiber was re-purposed for use in LANs, such as Fiber Distributed Data Interface (FDDI), then under development.

  7. Mandrel wrapping - Wikipedia

    en.wikipedia.org/wiki/Mandrel_wrapping

    In multimode fibre optics, mandrel wrapping is a technique used to preferentially attenuate high-order mode power of a propagating optical signal. Consequently, if the fibre is propagating substantial energy in affected modes, the modal distribution will be changed.
