Multimode Fiber Cable Diameter

The attenuation of multimode fiber is higher than sm fiber because of its larger core diameter.

Multimode fiber cable diameter. Om1 om2 om3 and om4. 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. Some types are single mode and some types are multimode. Usually the diameter of the multimode fiber is either 50 125 µm or 62 5 125 µm.

The cladding diameter of single mode and multimode fiber is 125 µm. Fiber optic cable can be divided into several types. Multimode fibers are described by their core and cladding diameters. 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 we see single mode and multimode fiber types available on the market. Om1 and om2 are both orange jacketed cable and you cannot judge from the outer diameter to identify om1 and om2 fiber cable. Multimode fiber is usually 50 125 and 62 5 125 in construction. The size of the optical fiber is commonly referred to by the outer diameter of its core cladding and coating.

Multimode fibers are described by their core and cladding diameters. Om2 is a standard for multimode cable defined by iso iec 11801. At present there are four kinds of multi mode fibers. 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.

50 125 250 indicates a fiber with a core of 50 microns cladding of 125 microns and a coating of 250 microns. Multi mode links can be used for data rates up to 100 gbit s. Rf broadband signals such as what cable companies commonly use cannot be transmitted over multimode fiber.
