A fiber optical signal is based on the transfer of photons, while an electrical signal is based on the transfer of electrons.

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 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.


Can you propagate optical signal over electrical network?

only over fiber


Difference between active and passive optical component?

Fiber optic couplers can be either active or passive devices. The difference between active and passive couplers is that a passive coupler redistributes the optical signal without optical-to-electrical conversion. Active couplers are electronic devices that split or combine the signal electrically and use fiber optic detectors and sources for input and output.


What are the important blocks of point to point links in optical communication.?

In optical communication, important blocks of point-to-point links include the light source (typically a laser), which generates the optical signal; the optical fiber, which transmits the signal over distances; and the photodetector, which converts the received optical signal back into electrical form. Additional components may include amplifiers to boost signal strength, multiplexers and demultiplexers for combining and separating multiple signals, and various types of connectors and splices for ensuring effective signal transmission. These elements work together to ensure efficient and reliable communication over optical networks.


Is light the only signal carrier in optical fibers?

Yes, light is the primary signal carrier in optical fibers. It travels through the fiber as pulses of light, typically in the form of laser or LED signals. Other signals such as electrical signals can be converted into light signals at the source and back to electrical signals at the receiving end.


A device that transfers a signal from one form to another is?

A device that transfers a signal from one form to another is called a transducer. Transducers can convert various types of signals, such as electrical, mechanical, thermal, or optical signals, into different forms for communication or processing in electronic systems.


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 the difference between primary and secondary transducers?

the difference between both are: Primary transducer:The Mechanical device which converts physical quantity to be measured into a mechanical signal. Secondary tranducer:The Electrical device which converts this mechanical signal to the electrical signal.


What is mean by signal?

Signal is the electrical(discussion is confined to electrical domain only) quantity which varies between two levels and holds some useful information.


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.
