The difference between single-mode and multi-mode fiber optic transceivers

5/29/15  |  Technical Article

Fiber optic transceiver is a twisted pair electrical short distance and long-distance optical signal transmission swap Ethernet media conversion unit, also known as the photoelectric converter or fiber optic converters. Today a wide range of fiber optic transceivers, but generally classified as single-mode and multimode. Singlemode multimode fiber is by nature classification.

Only a single propagation path single-mode fiber generally used for long distance transmission, multi-mode fiber has a variety of propagation path, multimode fiber bandwidth 50MHz ~ 500MHz / Km, single-mode fiber bandwidth 2000MHz / Km, the optical fiber wavelength 850nm, 1310nm and 1550nm and so on. 850nm wavelength multimode fiber communications; 1550nm wavelength single-mode optical fiber communications; two multi-mode and single-mode 1310nm wavelength; 850nm attenuation larger, but for 2 ~ 3MILE (1MILE = 1604m) communication more economical. Optical fiber by fiber diameter size delineation 50μm multimode fiber with slowly decreasing, 62.5μm slowly varying enhanced multimode fiber and singlemode fiber 8.3μm mutant, cladding diameter fiber are 125μm, therefore, 62.5 / 125μm, 50 / 125μm , 9 / 125μm and other different types. Therefore, single-mode fiber optic transceivers and multimode difference is that there are single mode and multimode optical fiber of the points.
