optical fibre
Học thuậtThân thiện
A technician carefully examines a single optical fibre against a light source.
Definition
- Noun:
- A very thin, flexible strand of transparent glass or plastic that transmits light along its length: An optical fibre is a physical medium that uses the principle of total internal reflection to guide light pulses, typically for the purpose of transmitting data, images, or illumination.
Usage Examples
- Noun:
- The internet connection in our building is provided via optical fibre.
- Surgeons use bundles of optical fibre to see inside the human body during endoscopic procedures.
- The new undersea cable contains dozens of optical fibres to carry telecommunications between continents.
Advanced Usage
- "fibre-optic" (adjective): Describes technology, cables, or systems that use optical fibres.
- The hospital installed a fibre-optic network for faster data transfer between departments.
- "to lay optical fibre": The process of installing fibre cables underground or underwater.
- The company is laying optical fibre throughout the neighbourhood to upgrade the network.
Variants and Related Words
- Fiber optics (noun, often used with a singular verb): The branch of science and technology concerned with the transmission of light through fibres.
- He studied fiber optics in university.
- Fiber-optic cable (noun): A cable containing one or more optical fibres, protected by layers of strength members and sheathing.
- The main backbone of the internet consists of thick fiber-optic cables.
Synonyms
- Light guide: A general term for any device that directs light, including optical fibres.
- Glass fibre (in this specific context): Can be used informally, though it specifies the material.
Related Phrases
- Optical fibre network: A telecommunications network built using optical fibre technology.
- The country is investing heavily in a national optical fibre network.
- Optical fibre communication: The method of transmitting information from one place to another by sending pulses of light through an optical fibre.

Related Concepts
- Total Internal Reflection: The physical principle that allows light to be guided along an optical fibre.
- Bandwidth: The high bandwidth (data-carrying capacity) of optical fibre is one of its key advantages over copper wire.
- Attenuation: The reduction in signal strength (loss of light) as it travels along the fibre, which is very low in modern optical fibres.
