In fiber-optic communication, a single-mode optical fiber (SMF), also known as fundamental- or mono-mode, [1] is an optical fiber designed to carry only a single mode of light - the transverse mode. Modes are the possible solutions of the Helmholtz equation for waves, which is obtained by combining Maxwell's equations and the boundary conditions.
Built-in variable optical attenuators may be either manually or electrically controlled. A manual device is useful for one-time set up of a system, and is a near-equivalent to a fixed attenuator, and may be referred to as an "adjustable attenuator". In contrast, an electrically controlled attenuator can provide adaptive power optimization.
G.652 is an international standard that describes the geometrical, mechanical, and transmission attributes of a single-mode optical fibre and cable, developed by the Standardization Sector of the International Telecommunication Union that specifies the most popular type of single-mode optical fiber (SMF) cable.

Please help improve it to make it understandable to non-experts, without removing the technical details. ( May 2024 ) ( Learn how and when to remove this message ) In telecommunications , a mode scrambler or mode mixer is a device for inducing mode coupling in an optical fiber , or a device that, itself, exhibits a uniform output intensity ...
Commercial single-photon avalanche diode module for optical photons. A single-photon avalanche diode (SPAD), also called Geiger-mode avalanche photodiode [1] (G-APD or GM-APD [2]) is a solid-state photodetector within the same family as photodiodes and avalanche photodiodes (APDs), while also being fundamentally linked with basic diode behaviours.
