Types of fiber optics

Depending on the format of the Refractive Index Profile, the fiber optics are divide into Step Index and Graded Index:

 

  • The Step Index is a fiber that has a refractive index or refraction index of the core. Step Index cables are Single-Mode Step Index (SM-SI) and Multi-Mode Step Index (MM-SI) cables.
  • Grade Index fiber optic fiber is a fiber that has a variable deflection index, i.e. the deflection index has a maximum value at the axis of the wire and gradually decreases with the distance from the axis to the circumference of the conductor. The cladding, where the refractive index of the cladding is equal to the cladding. For the Graded Index, they have the Graded Index Multi-Mode (GI-MM) cable.
  • A mode is a trajectory adopted by the wavelength of a light as it travels through the optical fiber. Multimode means multiple pathways of optical light represented by multiple wavelengths.

  • Single Mode cables are use with light sources such as Laser Amplification (Light Amplification by Simulated Emission of Radiation) because the diodes emit coherent light with a narrow beam suitable for single fiber optics. Mode with a small diameter (about 8-9 micrometers) with a single light path. Coral light is light that has the same frequency and wavelength.

  • Multimode cables are use with a light source as a light emitting diode because the LEDs emit different incoherent light in a large light package that is suitable for the cable. Multimode optics with a diameter of about 50-60 micrometers allow a lot of non-Koran light, represented by different wavelengths, to run in different orbits.
