Multimode Fiber Cable Diameter

Fiber optic cable can be divided into several types.

Multimode fiber cable diameter.

The cladding diameter of single mode and multimode fiber is 125 µm. Some types are single mode and some types are multimode. The diameter of the multi mode fiber is either 50 125 µm or 62 5 125 µm. Multimode fibers are described by their core and cladding diameters.

The attenuation of multimode fiber is higher than sm fiber because of its larger core diameter. There are different types of fiber optic cable. Multi mode fiber has a fairly large core diameter that enables multiple light modes to be propagated and limits the maximum length of a transmission link because of modal dispersion. The fiber core of single mode cable is very narrow so the light that passes through these fiber optical cables is not reflected too many times which keeps the attenuation to a.

This means that the core to cladding diameter ratio is 50 microns to 125 microns and 62 5 microns to 125 microns. Om2 is a standard for multimode cable defined by iso iec 11801. Multimode fiber is usually 50 125 and 62 5 125 in construction. Rf broadband signals such as what cable companies commonly use cannot be transmitted over multimode fiber.

Om1 om2 om3 and om4. Multi mode optical fiber is a type of optical fiber mostly used for communication over short distances such as within a building or on a campus. Usually the diameter of the multimode fiber is either 50 125 µm or 62 5 125 µm. 50 125 250 indicates a fiber with a core of 50 microns cladding of 125 microns and a coating of 250 microns.

Multimode fibers are described by their core and cladding diameters. Om1 and om2 are both orange jacketed cable and you cannot judge from the outer diameter to identify om1 and om2 fiber cable. At present there are four kinds of multi mode fibers.
