Optical signals in optical cables have short wavelength why?
Because the attenuation of the fiber is much less at those wavelengths.
How do you maintain fiber optical cabel?
by cleaning them regularlly
What is full form of OFC in lease line?
Optical Fiber Cabel
How does an optical transmitter sends signals to the optical fiber?
Usually, there is a laser diode that is optically coupled to the fiber.
What is used in optical fiber communication?
WDM wavelength division multiplexing
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.
Why is it a problem is optical fiber signals need boosting frequently?
so stupid
How can any individual IP packet be communicated electrically?
over cable, as optical signals over fiber, or wirelessly as radio signals
A modern device that often has its signals carried through wires or glass optical fiber is a what?
telephone
What is used to convert fiber optic light transmissions to electrical signals?
Fiber-optic communication refers to the transmission of information using optical fiber. Opto-electronic repeaters are used to convert fiber optic light transmissions to electrical signals.
Is fiber optics and Fiber optic sensors are same?
No, A fiber optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors").
What is meant by attenuation in optical fiber?
When an optical signal of a given wavelength travels in the fiber it looses power. The amount of loss of power per Km length of fiber is called its attenuation. A=10*LOG10(POUT/PIN) dB/Km Where POuT is optical power after 1 Km PIN is th epower launched in the Fiber.
