A single muscle cell is called a muscle fiber.

From Wikipedia, below: "The quality of wool is determined by its fiber diameter, crimp, yield, color, and staple strength. Fiber diameter is the single most important wool characteristic determining quality and price."
Single Mode cable is a single stand (most applications use 2 fibers) of glass fiber with a diameter of 8.3 to 10 microns that has one mode of transmission. Single Mode Fiber with a relatively narrow diameter, through which only one mode will propagate typically 1310 or 1550nm. Carries higher bandwidth than multimode fiber, but requires a light source with a narrow spectral width. Synonyms mono-mode optical fiber, single-mode fiber, single-mode optical waveguide, uni-mode fiber.

The contractile response of a single muscle fiber to a single muscle impulse is called a "twitch." A twitch consists of a brief contraction followed by relaxation, and it can be divided into three phases: the latent period, contraction phase, and relaxation phase. The characteristics of a twitch, such as its duration and force, can vary depending on the type of muscle fiber involved.
Optical fiber is typically very thin, with a core diameter ranging from about 8 to 62.5 micrometers, depending on the type of fiber (single-mode or multi-mode). When including the protective cladding and outer jacket, the total diameter of the fiber can range from about 125 micrometers to several millimeters. This allows for high data transmission speeds over long distances while being lightweight and flexible.
mode means path, the way in which light travel, in the fiber means angle in multi mode fiber light can travel in more then one angle so it is called multi mode fiber. but in single mode fiber there is dedicated path or single path through which light beam/source can travel.
Probably, you can measure the diameter of a wool fibre and get the answer you want.
The smallest unit of textile material is a fiber. The length of a fiber is greater than the diameter.
