Single Mode Fiber Information

Single mode fiber cable (Synonyms mono-mode optical fiber, single-mode fiber, single-mode optical waveguide, uni-mode fiber) is a single strand of glass fiber with a diameter of 8.3 to 10 microns that has one mode of transmission. Single mode fiber has a relatively narrow diameter, through which only one mode will propagate typically 1310 or 1550nm wavelengths. Single mode fibers carry higher bandwidth than multimode fiber, but require a light source with a narrow spectral width. Single-mode fiber gives you a higher transmission rate and up to 50 times more distance than multimode. The small core and single light-wave virtually eliminate any distortion that could result from overlapping light pulses, providing the least signal attenuation and the highest transmission speeds of any fiber cable type.
