In fiber optic communication, single mode fiber (SMF) is a type of fiber that directly transmits optical signals in transverse mode. Single mode optical fiber can operate at a data rate of 100M/s or 1 G/s, and the transmission distance can reach at least 5 kilometers. Typically, single mode optical fibers are used for remote signal transmission.
What is multimode fiber
Multimode optical fiber (MMF) is a common type of optical fiber, with a working wavelength of 850nm/1300nm, supporting hundreds of transmission modes, and has advantages such as high bandwidth and low cost. It is suitable for short distance optical fiber transmission (such as computer rooms). The refractive index of multimode fibers can be divided into two types: gradient and step.
Multi mode fiber optic (MMF) is mainly used for short distance fiber optic communication, such as in buildings or campuses. The typical transmission speed is 100M/s, the transmission distance can reach 2km (100BASE-FX), 1 G/s can reach 1000m, and 10 G/s can reach 550m. There are two types of refractive indices: gradient refractive index and step refractive index.
