Usually, there is a laser diode that is optically coupled to the fiber.
One of the advantages of optical fiber is that it is NOT susceptible to cross-talk.
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?
no, its cylindrical
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.
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.
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.
what is fiber optics what is fiber optics
Yes, they are the exact same thing
