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 .

How audio signal convert into electrical signal?
microphone............
What is meant by atenuation in fiber optics?
Attenuation in fiber means 'loss of optical power' suffered by the optical signal in fiber itself.
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.
How do you convert voice signal to voltage?
different method are available for converting voice signal to volage ......one method is sence presure variation from the out put of mic by using presure tranducer ..out of transducer should be a volage .this volage is amplified by using amplifier cicuit and it amplified signal or volge is store in to battery or other storig device.......
How do you convert smell to electrical signal?
There are no COTS sensors capable of doing this. The military and police still use dogs to detect smells, but they can't be connected to electronics.
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
How audio signal convert into electrical signal?

Can you propagate optical signal over electrical network?
only over fiber
What is function of pressure transmitter?
a pressure transmitter is a devise to measure the mechanical pressure and convert in to electrical signal it may be 4~20mA or 0~10V
What are optical sensors used for?
Optical sensors convert light, or changes in light, into electrical signals. They are used in products such as automatic lighting and flashes for cameras.
What is Relationship between electrical and optical bandwidth for an optical fiber communication?
The electrical bandwidth refers to the frequency range that the electronic components in the communication system can handle, while optical bandwidth refers to the frequency range that the optical fiber can transmit. The relationship between the two bandwidths is important in ensuring that the data transmission is efficient and reliable. Matching the electrical and optical bandwidths helps to avoid signal degradation and distortion in the communication system.
What is GBIC stand for?
GBIC stands for Giga Bit Interface Converter. The primary function of this fiber connectivity device is to convert serial electrical signal to optical signal and vice versa. These devices are hot swappable (The network appliance that they are plugged into, does not have to be powered down) and are generally used in switches and routers.
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 is optical communication?
An optical fiber is a flexible, transparent fiber made of very pure glass (silica) not much bigger than a human hair that acts as a waveguide, or "light pipe", to transmit light between the two ends of the fiber. The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communication. Fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles so they can be used to carry images, thus allowing viewing in tight spaces. Specially designed fibers are used for a variety of other applications, including sensors and fiber lasers.
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.
Do Fiber-optic cable send or receive electrical signal?
No. Fibre optic cables use light instead of electrical signals. Depending on the function of the optical fibre either a laser or an LED will be used.
