What portion of the electromagnetic spectrum is used in optical fiber communication?
Fiber optic cables use wavelengths of visible light to transmit data. (Some use infrared as well.) They use red and above with the higher wavelengths being of higher speed and quality. The higher the wavelengths of light used, the more expensive the equipment is.
Is fiber optic communication better than electric communication?
yes. fiber optic communications literally move at the speed of light, while electric communication is limited to the wire used to transmit the data
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.
What has a longer wavelength red light or infrared light?
infrared
What are infrared rays?
Infrared rays are electromagnetic waves with a wavelength longer than the wavelength of visible 'red' light [or you could say they have a lower frequency than red light]. Infrared 'light' is used in TV remote controls to transmit information to an infrared receiver on the TV, and also in security systems to create an invisible 'light beam' that when broken, will send a signal back to the system.
Starburst galaxies are especially bright in visible light ultraviolet light or infrared light?
infrared light
Fiber optic uses what kind of signal?
Optical signals (usually on the infrared band) optical s ignals generally mean visible light... so it mainly uses visible light.
What is the technology merges computing with high speed communication?
Fiber optics, which allow data to flow @ the speed of light
A sentence with the word infrared?
Infrared light is light with a longer wavelength than red. Here are some sentences.Humans cannot see infrared light without special goggles.Infrared light creates a lot of heat.Many animals can see infrared light.
Why can UV light cause cancer and not infrared light?
UV light can be turned into infrared light u dofus. DANJUIN
Is infrared man made?
No. Infrared is light (that we can't see) and light is NOT man made.
When was infrared created?
Infrared light was not invented, but is a natural wavelength of light found in nature.
