|
|
domieszka (substancja domieszkująca)
|
|
|
cladding with slightly lower refractive index This difference in refractive indices allows the fiber to perform Total Internal Reflection inside the fiber and propagate light down its length start learning

|
|
Radiation modes carry energy out of the core; the energy is quickly dissipated. start learning
|
|
|
|
|
Guided modes are confined to the core, and propagate energy along the fiber, transporting information and power. start learning
|
|
|
|
|
the modes are excited to varying degrees When light is launched into a fiber, the modes are excited to varying degrees depending on the conditions of the launch — input cone angle, spot size, axial centration and the like. start learning

a few factors (that contribute to the type of mode propagation a fiber will demonstrate) indices of refraction of core and cladding, core diameter, and wavelength. start learning

|
the sine of the largest angle an incident ray can have for total internal reflectance in the core. A higher core index, with respect to the cladding, means larger NA start learning
|

|
|
|
Qualitatively, (NA is a measure of the light gathering ability of a fiber. It also indicates how easy it is to couple light into a fiber) start learning
|
|
Jakościowo (NA jest miarą zdolności do gromadzenia światła przez światłowód, wskazuje również, jak łatwo jest sprzęgać łączyć z włóknem)
|
|
|
Many fiber parameters can be expressed in terms of V, such as: the number of modes at a given wavelength, mode cut off conditions, and propagation constants. start learning
|
|
|
|
|
Bandwidth of an optical fiber determines the data rate. The mechanism that limits a fiber’s bandwidth is known as dispersion. There are two main categories of dispersion, intermodal and intramodal. start learning
|
|
|
|
|
The index of refraction varies depending upon wavelength. Therefore, different wavelengths will travel down an optical fiber at different velocities. This is known as Chromatic Dispersion. start learning
|
|
Współczynnik załamania zmienia się w zależności od długości fali
|
|
|
needed to maintain acceptable signal levels. attenuation start learning
|
|
|
|
|
(In the near infrared and visible regions) the small absorption losses (of pure silica) Impurities — notably water in the form of hydroxyl ions — are much more dominant causes of absorption in commercial fibers. start learning
|
|
(W bliskiej podczerwieni i Vis) małe straty absorpcji (czystej krzemionki)
|
|
|
Scattering (can couple energy from guided to radiation modes) Any process that imposes dimensional irregularities — such as microbending — increases scattering and hence attenuation. start learning
