What are the advantages of using optical fiber instead of radio waves to carry signals?
see www.soe.ucsc.edu/classes/cmpe150/Fall05/lecture6.ppt for the answer
AnswerThe biggest is less attenuation (degradation) of signal, so that a message can travel significantly further over an optical fibre than over a copper (twisted pair of coax) cable before it becomes too garbled to understand. In addition, fibre optic cables are generally immune to electromagnetic interference (such as strong electrical or magnetic fields) nearby, while copper cables can have such interference reduce or completely destroy their ability to carry signals. Finally, it is much easier to transmit on multiple channels (frequencies) over fibre than over copper, so a fibre optic cable can handle many more simultaneous message streams than twisted pair or coax.In short: fibre allows hugely greater distances between endpoints, is practically immune to outside interference, and can handle hundreds or thousands of times more signal channels than twisted pair or coaxial cable.

Waves used for broadcastig radio signals are called what?
The waves used to broadcast radio signals are called RF waves and these generally lie in VHF and UHF band of electromagnetic spectrum.
What are some advantages of playing guitar 'fingerstyle'?
The fingerstyle guitar technique has a few advantages. One does not need to carry a pluck to play a guitar, non-adjacent strings can be played simultaneously, and it becomes easier to play arpeggios.
__________ transmit signals that carry pictures, data, music and conversations invisibly over long distances and have been the basis for almost all non-written communication and most wireless technologies used by humans today.?
radio waves

Carry On My Wayward Son - Kansas Carry That Weight - The Beatles Carry On - Justin Timberlake
Did beyonce carry her own baby or did she have someone else carry her baby?
No she had someone carry it
What type of waves carry optical fibre signals?
Light waves carry optical fiber signals. These waves are typically in the infrared range and are able to travel long distances through the fiber without losing signal strength.
What is a video transceiver used for?
It's used to send video and/or audio from one location to another - usually as part of a security system. It sends the pictures and sound via radio waves (instead of cables) over a short distance. They're illegal in some countries, because they use radio frequencies that are already allocated to existing services - causing interference to legitimate users. Optical video transceivers are used to transform between the video signals and fiber optic signals, although its name is video transceiver, nowadays optical video transceiver can carry the data signals and audio signals too. Currently the most popular type is the digital video optical video transceivers. Source: FiberStore
What kind of light is used to carry information through optical fibers?
Typically, light in the form of laser beams is used to carry information through optical fibers. The laser light pulses encode data that is transmitted through the fibers in the form of light signals.
What is the basis for all telecommunications signals?
The basis for all telecommunications signals is the transmission of data through electronic or optical signals. These signals carry information such as voice, video, or text over different mediums like cables, airwaves, or fiber optics. The signals are encoded and decoded using specific protocols to ensure accurate and secure communication.
Does s video cables carry audio signals?
No. They only carry separated color signals.
Can laser beams carry signals like radio waves?
Yes, laser beams can carry signals just like radio waves, but they are typically used in optical communication systems. Laser beams have a higher frequency and bandwidth compared to radio waves, making them suitable for high-speed data transmission over shorter distances through optical fibers.
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 photonic networks?
A photonic (or optical) network is a communications network in which information is transmitted entirely in the form of optical or infrared transmission(IR) signals. In atrue photonic network, every switch and every repeater works with IR or visible-lightenergy. A recent development in this field is the erbium amplifier. Conversion toand from electrical impulses is not done except at the source and destination (origin andend point).
What part of the spectrum carries TV signals through optical fiber cables?
Fiber optic cables carry light, not radio frequency energy. Somewhat like comparing apples to nuts.
How is light used to transmit information in modern communication systems?
Light is used to transmit information in modern communication systems through optical fibers. These fibers carry light signals that encode data, such as text, images, and videos, over long distances at high speeds. The light signals are converted into electrical signals at the receiving end to retrieve the transmitted information.
What is SPDIF?
S/PDIF or Sony Philips Digital Interconnect Format is a standard/protocol that specifies transmission of audio signals from one device to another in digital format. Both coaxial electrical cable and an optical fiber cable can be used to carry signals in S/PDIF format. - Neeraj Sharma
What method of signal transmission uses radio waves to carry signals?
The analog method of signal transmission uses radio waves to carry signals. Digital transmission involves the use of satellites to transmit signals.
