Complete Introduction to Multimode and Singlemode Fiber
Fiber optics are the most basic and commonly used product in the field of communications.. Optical fiber can be divided into single-mode optical fiber and multimode optical fiber.. in a short sentence, single-mode optical fiber is suitable for long-distance communication transmission, while multimode optical fiber is suitable for short-distance communication transmission. Singlemode Optical Fiber When the geometric dimensions of the optical fiber (mainly the core diameter) are close to the wavelength of light, as a core diameter d1 in the range of 5~10µm, Fiber optics only allow one mode propagation (basic mode HE11), with all other higher modes completely dimmed....
