  2. Gap loss - Wikipedia

    en.wikipedia.org/wiki/Gap_loss

    Gap loss is a type of signal strength loss that occurs in fiber optic transmission when the signal is transferred from one section of fiber or cable to another. [ 1 ] The three basic types of gap loss are angular misalignment loss, lateral offset loss, and longitudinal displacement loss.

  3. Fiber-optic communication - Wikipedia

    en.wikipedia.org/wiki/Fiber-optic_communication

    The main benefits of fiber are its exceptionally low loss (allowing long distances between repeaters), its absence of ground currents and other parasite signal and power issues common to long parallel electric conductor runs (due to its reliance on light rather than electricity for transmission, and the dielectric nature of fiber optic), and ...

  4. Optical fiber - Wikipedia

    en.wikipedia.org/wiki/Optical_fiber

    Attenuation in fiber optics, also known as transmission loss, is the reduction in the intensity of the light signal as it travels through the transmission medium. Attenuation coefficients in fiber optics are usually expressed in units of dB/km.

  5. Attenuation - Wikipedia

    en.wikipedia.org/wiki/Attenuation

    Attenuation in fiber optics, also known as transmission loss, is the reduction in intensity of the light beam (or signal) with respect to distance travelled through a transmission medium. Attenuation coefficients in fiber optics usually use units of dB/km through the medium due to the relatively high quality of transparency of modern optical ...

  6. Return loss - Wikipedia

    en.wikipedia.org/wiki/Return_loss

    In telecommunications, return loss is a measure in relative terms of the power of the signal reflected by a discontinuity in a transmission line or optical fiber.This discontinuity can be caused by a mismatch between the termination or load connected to the line and the characteristic impedance of the line.

  7. Link budget - Wikipedia

    en.wikipedia.org/wiki/Link_budget

    A link budget is an accounting of all of the power gains and losses that a communication signal experiences in a telecommunication system; from a transmitter, through a communication medium such as radio waves, cable, waveguide, or optical fiber, to the receiver.

  8. Radiation effects on optical fibers - Wikipedia

    en.wikipedia.org/wiki/Radiation_effects_on...

    When optical fibers are exposed to ionizing radiation such as energetic electrons, protons, neutrons, X-rays, Ƴ-radiation, etc., they undergo 'damage'. [1] [2] The term 'damage' primarily refers to added optical absorption, resulting in loss of the propagating optical signal leading to decreased power at the output end, which could lead to premature failure of the component and or system.

  9. Optical power budget - Wikipedia

    en.wikipedia.org/wiki/Optical_power_budget

    The optical power budget (also fiber-optic link budget and loss budget) in a fiber-optic communication link is the allocation of available optical power (launched into a given fiber by a given source) among various loss-producing mechanisms such as launch coupling loss, fiber attenuation, splice losses, and connector losses, in order to ensure that adequate signal strength (optical power) is ...
