Single-mode fiber (Single-mode fiber), light enters the fiber at a specific angle of incidence and complete emission occurs between the fiber and the cladding. When the diameter is small, light is only allowed to pass in one direction, which is a single-mode fiber; single-mode fiber; Modal fibers have a thin central glass core, typically 8.5 or 9.5 mm in diameter. mm in diameter, and operate at wavelengths of 1310 and 1550 nm.
Multimode fiber is a fiber which allows the transmission of multiple guided modes. The core diameter of a multimode fiber is generally 50 mm/62,5 mDue to the large core diameter of a multimode fiber, light of different modes can be transmitted within a single fiber. The standard wavelengths for multimode fiber are 850 nm and 1300 nm, respectively. There is also a newer multimode fiber standard called WBMMF (Wideband Multimode Fiber), which uses wavelengths between 850 nm and 953 nm.
Single-mode fiber and multi-mode fiber, both with a cladding diameter of 125 mm.
