Single mode cable is a single stand (most applications use 2 fibers) of glass fiber with a diameter of 8.3 to 10 microns that has one mode of transmission. Single mode fiber with a relatively narrow diameter, through which only one mode will propagate typically 1310 or 1550nm. Carries higher bandwidth than multimode fiber, but requires a light source with a narrow spectral width.
Single-mode fiber gives us a higher transmission rate and up to 50 times more distance than multimode, but it also costs more. Single-mode fiber has a much smaller core 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.
Multi mode cable diameter is a little big, with a common diameters in the 50-to-100 micron range for the light carry component (in the United States, the most common size is 62.5um). In most applications, the use of multimode optical fiber, two fibers (WDM, usually without the use of multimode fiber). POF is a relatively new based on the plastic of the cable, the cable's commitment is similar to that of the performance on the glass cable very short run, but at a lower cost.

Which types fiber to install ? This is based on transmission distance to be covered as well as the overall budget allowed. If the distance is less than a couple of miles, multimode fiber will work well and transmission system fiber optic cable price (transmitter and receiver) will be in the $500 to $800 range. If the distance to be covered is more than 3-5 miles, single mode fiber is the choice. Transmission systems designed for use with this fiber will typically cost more than $1000 (due to the increased cost of the laser diode).
If you have single-mode fiber indtalled, but only go a short distance. you can not use multimode equipment for lower cost. Multimode equipment will not inject enough light into a single-mode fiber since the light carrying core of this fiber is only 9 microns in diameter compared to 62.5 microns in diameter for multimode fiber. Unfortunately you must use single-mode equipment. If the fiber distance is short however, the cost for replacing the single-mode fiber with multimode fiber may be more economical than the higher cost for the single-mode electronics.
