In telecommunication, the term cutoff wavelength has the following meanings:
- The wavelength corresponding to the cutoff frequency.
- In an uncabled1 single-mode optical fiber, the wavelength greater than which a particular waveguide mode ceases to be a bound mode.
The cutoff Cutoff wavelength wavelength is usually taken to be the wavelength at which the normalized frequency is equal to 2.405.
Notes
Note 1: : The cabled cutoff wavelength is usually considered to be a more functional parameter because it takes into consideration the effects of cabling the fiber.
Electronics Topics
The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the fields of electronic engineering, and the hardware design side of computer engineering. The study of new semiconductor devices and their technology is sometimes considered as a branch of physics.
