How you can convert an electrical signal into an optical signal?
electrical signal can be converted to an optical sigal by using a LED or SOA(semiconductor optical amplifier). LED is the cheaper option but have the drawback of larger linewidth. Typically used for LAN (local area network). SOA produces an optical signal mostly by direct modulation tecnique .
What is meant by atenuation in fiber optics?
Attenuation in fiber means 'loss of optical power' suffered by the optical signal in fiber itself.
What the importance of intrinsic factor?
Intrinsic factor is glycoprotein that is produced by the parietal cells of the stomach.
What is the basic principle of fiber sensor?
A fiber optic sensor in general consists of a light source. The light source is coupled to an optical fiber. A light source which receives signal-carrying light beam on it emerges from the fiber. The signal from detector is processed electrically for getting information.
How can you convert the digital signal given on the speedometer in the car into radio waves which can be received some where else?
First of all digital signal cant be transmitted wirelessly. digital signal can only be transmitted through optical fibre in the form of pulses. so we have to convert digital signal to analog form with the help of DIGITAL TO ANALOG CONVERTOR ( D TO A CONVERTOR). Then this analog signal should be super imposed on carrier signal called MODULATION. modem can be used for that. then that signal can be transmitted to the air through alloted band width like cellular system with the help of transceiver. at the reciveing end we can demodulate the signal with the help of modem & can convert it back to digital form through A TO D CONVERTOR.
What has the author Richard S Yoon written?
Richard S. Yoon has written: 'The characterization of cortical spreading depression in rats using intrinsic optical signal'
What is different between optical fiber signal and electrical signal?
A fiber optical signal is based on the transfer of photons, while an electrical signal is based on the transfer of electrons.

How camera tube in TV converts optical signal into electrical signal?
hi
What is the function of detector in UV spectrophotometer?
Detector converts optical signal to electric signal
What optical fiber used for?
Long Distance signal transmission!
Is light the only signal carrier in optical fibers?
yes
What is analog signal full definition?
a continuously variable signal. it could be electronic, mechanical, hydraulic, optical, etc.
Can you propagate optical signal over electrical network?
only over fiber
Part of the eye that detects light and sends signal to brain?
The retina detects light and the optical nerve sends the signal to the brain.
Does the gauge of fiber optical audio cable affect the audio quality?
No. As long as the signal is getting through, the gauge of the optical connection makes no difference.
