What does multimode mean?
Multimode describes a system, device, or process that can operate in more than one mode. “Mode” here means a distinct way of functioning, transmitting, processing, or representing information, rather than a simple mood or style. The word is especially common in computing, telecommunications, and engineering. For example, multimode fiber can carry light along several paths simultaneously, while a multimode laser may operate at more than one wavelength or spatial mode. In software and media contexts, the term can refer to systems that support several kinds of input, output, or interaction. Multimode is the opposite of monomode or single-mode, which describes a system restricted to one mode of operation. Although often written as one word, “multi-mode” is also used, particularly in technical specifications. The term is more precise than simply saying “multiple” because it refers specifically to distinct operating modes.
Involving or operating in more than one mode.
"The laboratory is testing a multimode optical sensor."
Chiefly used in technical and scientific contexts.
A device or system that operates in more than one mode.
"The instrument is a multimode, allowing it to serve several measurement tasks."
Less common than the adjectival use; usually encountered in specialist technical writing.
In a multimode fiber, light can travel along several optical paths at once, making the technology especially useful for short-distance, high-volume data connections.

How multimode is actually used
The term is chiefly used in technical writing. It is commonly written as a closed compound, though “multi-mode” also occurs, especially in telecommunications and optical-fiber terminology.
Easily confused with multimode
Multimode refers to operation in multiple technical modes, whereas multimodal describes something involving more than one mode of communication, expression, or data.
