Do fiberoptic cables use lasers, or regular light? (or can they use either depending on the situation)
 
Science news on Phys.org

Fibre optics will carry any light depending on the wavelength they are designed for.
Telecoms applications generally use lasers, they are high power, have a well controlled wavelength and you can switch them quickly.

Thank you.

I thought they used lasers, but couldn't find a source for that.

They can use either, as mgb_phys said.

Here is an example where regular visible light is transmitted by fibers:

FAQ: Fiber Optics & Lasers: Light Usage

What are fiber optics and lasers?

Fiber optics and lasers are technologies that use light to transmit and manipulate information. Fiber optics use thin, transparent fibers to carry light signals over long distances, while lasers use concentrated beams of light to perform precise functions.

How are fiber optics and lasers used in everyday life?

Fiber optics are used in telecommunications to transmit data, such as internet and phone signals, over long distances. Lasers are used in various industries, such as medicine, manufacturing, and entertainment, for tasks such as cutting, welding, and reading barcodes.

What are the advantages of using fiber optics and lasers?

Fiber optics and lasers offer numerous advantages, including high bandwidth for fast data transmission, immunity to interference, and the ability to transmit signals over long distances without losing strength. Lasers also provide precise and controlled energy for various applications.

Are there any potential downsides to using fiber optics and lasers?

One potential downside is the high cost of installation and maintenance for fiber optics. They also require specialized equipment and expertise to install and repair. Lasers can be dangerous if not used properly, as they emit concentrated beams of light that can cause eye and skin damage.

What are some current developments in fiber optics and lasers?

Currently, there are efforts to increase the speed and capacity of fiber optics through advancements in materials and manufacturing techniques. In the field of lasers, there are developments in using them for medical treatments and in creating more efficient and powerful lasers for industrial applications.
