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

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.

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.
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.
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.
Depends. If they're all encoded for transfer by electronic means(radio, fiber, wire) they'll all travel at the same speed. But if you by audio signal mean sound in the air, then sound travels at about 700 miles an hour. A digital signal - electrical/optical - travels at the speed of light (186,282 miles per second) down a fiber network.
Network repeater regenerate incoming electrical, wireless or optical signals. With physical media like ethernet or Wi-Fi, data transmissions can only span a limited distance before the quality of the signal degrades. Repeaters attempt to preserve signal integrity and extend the distance over which data can safely travel.
Attenuation in fiber means 'loss of optical power' suffered by the optical signal in fiber itself.
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.
