Explain about optical fiber types modes and configurations?
fiber cable dia meeter
What is the optical range of optical fiber?
40 GHz
Is cross talk is possible in optical fiber?
One of the advantages of optical fiber is that it is NOT susceptible to cross-talk.
How does an optical transmitter sends signals to the optical fiber?
Usually, there is a laser diode that is optically coupled to the fiber.
Objective type question on optical fiber?
An objective type of question on optical fiber is on that focuses on the integral part of fiber optic. A good question would be, " Why are optical fibers immune to EMI? "
Describe refraction and reflection with respect to Fiber Optical Cable?
Describe refraction and reflection with respect to Fiber Optical Cable?
Is optical fiber spherical?
no, its cylindrical
Explain the propagation of light through optical fiber and appilication of optical fiber as wave guide and sensor?
The concept of light propagation, the transmission of light along an optical fiber, can be described by two theories. According to the first theory, light is described as a simple ray. This theory is the ray theory, or geometrical optics, approach. The advantage of the ray approach is that you get a clearer picture of the propagation of light along a fiber. The ray theory is used to approximate the light acceptance and guiding properties of optical fibers. According to the second theory, light is described as an electromagnetic wave. This theory is the mode theory, or wave representation, approach. The mode theory describes the behavior of light within an optical fiber. The mode theory is useful in describing the optical fiber properties of absorption, attenuation, and dispersion
What is fiber optic sensor?
An optical fiber is a glass or plastic fiber that carries light along its length. Fiber optics is the overlap of applied science and engineering concerned with the design and application of optical fibers.
Is fiber obtics a good conductor of electricity?
No. An optical fiber is a slim hair composed of glass. Glass is a fine insulator, and an optical fiber doesn't conduct electricity at all.
Is optical fiber unidirectional?
The optical fiber can be used both as unidirectional and bidirectional. The main application of optical fiber is in long-distance links, so there exists no need to employ them as unidirectional. For each direction different wavelengths are used to modulat the signals. At the same time many bidirectional signals can travel through the same optical fiber.
