Multimode Fiber Cable Diameter

Multimode fibers are described by their core and cladding diameters.

Multimode fiber cable diameter.

Usually the diameter of the multimode fiber is either 50 125 µm or 62 5 125 µm. Om1 om2 om3 and om4. Om1 and om2 are both orange jacketed cable and you cannot judge from the outer diameter to identify om1 and om2 fiber cable. Fiber optic cable can be divided into several types.

Some types are single mode and some types are multimode. 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. 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 diameter of the multi mode fiber is either 50 125 µm or 62 5 125 µm.

Rf broadband signals such as what cable companies commonly use cannot be transmitted over multimode fiber. The size of the optical fiber is commonly referred to by the outer diameter of its core cladding and coating. The attenuation of multimode fiber is higher than sm fiber because of its larger core diameter. This means that the core to cladding diameter ratio is 50 microns to 125 microns and 62 5 microns to 125 microns.

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. 50 125 250 indicates a fiber with a core of 50 microns cladding of 125 microns and a coating of 250 microns. The cladding diameter of single mode and multimode fiber is 125 µm. Multi mode links can be used for data rates up to 100 gbit s.

There are different types of fiber optic cable. Usually we see single mode and multimode fiber types available on the market. Multimode fiber is usually 50 125 and 62 5 125 in construction.
