  2. 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 (), 1 Gbit/s up to 1000 m, and 10 Gbit/s up to 550 m.

  3. G.651.1 - Wikipedia

    en.wikipedia.org/wiki/G.651.1

    G.651.1 is an international standard [1] developed by the Standardization Sector of the International Telecommunication Union that specifies multi-mode optical fiber (MMF) cable. [ 2 ] History

  4. Waveguide (optics) - Wikipedia

    en.wikipedia.org/wiki/Waveguide_(optics)

    Optical fiber is typically a circular cross-section dielectric waveguide consisting of a dielectric material surrounded by another dielectric material with a lower refractive index. Optical fibers are most commonly made from silica glass , however other glass materials are used for certain applications and plastic optical fiber can be used for ...

  5. Optical fiber - Wikipedia

    en.wikipedia.org/wiki/Optical_fiber

    Fibers that support many propagation paths or transverse modes are called multi-mode fibers, while those that support a single mode are called single-mode fibers (SMF). [7] Multi-mode fibers generally have a wider core diameter [8] and are used for short-distance communication links and for applications where high power must be transmitted. [9]

  6. Multi-Object Spectrometer - Wikipedia

    en.wikipedia.org/wiki/Multi-Object_Spectrometer

    Basic principle of multi-object spectroscopy. A multi-object spectrometer is a type of optical spectrometer capable of simultaneously acquiring the spectra of multiple separate objects in its field of view. [1] It is used in astronomical spectroscopy and is related to long-slit spectroscopy. [2] This technique became available in the 1980s. [3]

  7. Chromo-modal dispersion - Wikipedia

    en.wikipedia.org/wiki/Chromo-modal_dispersion

    The input facet of a multimode fiber is placed at the lens focus such that the various spectral components are coupled into different fiber modes. The figure inset illustrates how different spectral components are coupled into and propagate in the multimode fiber. The dashed line represents the optic axis of the fiber.

  8. Mode scrambler - Wikipedia

    en.wikipedia.org/wiki/Mode_scrambler

    These were used for this purpose in the first U.S. NIST round-robins on multimode fiber. [1] The overfilled launch (OFL) was created to reduce measurement variability, and improve concatenation estimates for multimode fibers, used at that time for telecom 'long haul' (e.g., 7–10 km 850 nm or 20–30 km 1300 nm) systems.

  9. Optical tweezers - Wikipedia

    en.wikipedia.org/wiki/Optical_tweezers

    The standard fiber optical trap relies on the same principle as the optical trapping, but with the Gaussian laser beam delivered through an optical fiber. If one end of the optical fiber is molded into a lens -like facet, the nearly gaussian beam carried by a single mode standard fiber will be focused at some distance from the fiber tip.
