Is the Nyquist theorem true for optical fiber or only for copper wire?

∙ 11y ago
The Nyquist theorem is a property of mathematics and has nothing to do with technology. It says that if you have a function whose Fourier spectrum does not contain any sines or cosines above f, then by sampling the function at a frequency of 2fyou capture all the information there is. Thus, the Nyquist theorem is true for all media.

Is the Nyquist theorem true for high-quality single-mode optical fiber or only for copper wire?
The Nyquist theorem is a property of mathematics and has nothing to do with technology. It says that if you have a function whose Fourier spectrum does not contain any sines or cosines above f, then by sampling the function at a frequency of 2f you capture all the information there is. Thus, the Nyquist theorem is true for all media.

Describe refraction and reflection with respect to Fiber Optical Cable?
Is optical fiber ihollow or not?
The main part of an optical fiber is a glass fiber (NOT hollow) within another glass fiber of another type of glass. Both types of glass have a different index of refraction; the signal travels through the inner glass fiber.
Why optical fiber is slowly replacing copper cables in telecommunicaton?
Fiber lasts longer than copper, it has less signal attenuation, and its bandwidth capacity is much greater. It's just an all around better medium than copper. Plus, it costs almost exactly the same to deploy fiber as it does copper in new outside plant deployments - so you get all the benefits of fiber for no additional cost.
What is numerical aparture in optic fiber?
Numerical aparture is the light collecting capability of the optical fiber.
Is Nyquist theorem true for optical fiber?
I cannot see where the Nyquist theorem relates to cables, fiber or not.The theorem I know, the Nyquist-Shannon sampling theorem, talks about the limitations in sampling a continuous (analog) signal at discrete intervals to turn it into digital form.An optical fiber or other cable merely transport bits, there is no analog/digital conversion and no sampling taking place.

Which can transmit faster optical fiber or copper wire I read in an article that copper wire is faster than optical fiber?
Optical Fiber1. Photon has no mass, and it can travel faster than electron2. In multi-mode fiber, several channels of data can be transmitted at the same time
Why copper cables are transformed into optical fiber?
fibre has higher data capacity, takes less space, is cheaper, etc. than copper.
What are the disadvantages of using optical fiber instead of copper wire for communications?
Optical fiber carries signals through light, and therefore at light speed, the fastest possible, and gets less hot. Copper wire transmits information using electricity, which although fast, is not nearly as fast as light. Fiber optics allows faster transmission of data.
Different between fiber optical cable and copper cable?
Fiber optic cable is constructed out of glass or plastic, and uses light pulses to transmit data. Copper cable is made out of copper material (not glass or plastic) and uses electrical voltages to transmit signals.
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? "
What are the most commonly used media types in Ethernet network today?
1. Copper UTP (Unshielded Twisted Pair) 2. Optical Fiber
