Single-Mode Fiber (SMF):
Single-mode fiber is a mode of light and it is used for long-distance signal transmission which is through the light travels on the optical fiber. It is also called as uni-mode fiber, mono mode fiber, and single-mode optical wavelength.
These modes define the way the wave travels through space, for Example how the wave is distributed in space.
Waves can have the same mode but have different frequencies. This is the case in single-mode fibers, where we can have waves with different frequencies, but of the same mode, which means that they are distributed in space in the same way, and that gives us a single ray of light. Although the ray travels parallel to the length of the fiber.
Although the ray travels parallel to the length of the fiber, it is often known as transverse mode since its electromagnetic oscillations occur perpendicular (transverse) to the length of the fiber.
The Structure of a typical single-mode fiber.
1. Core 8 - 9 µm diameter
2. Cladding 125 µm diameter.
3. Buffer 250 µm diameter.
4. Jacket 900 µm diameter.
