Multimode Fiber Sizes

Some types are single mode and some types are multimode.

Multimode fiber sizes.

Om1 om2 om3 and om4. At present there are four kinds of multi mode fibers. 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. Single mode fiber and multimode fiber are not compatible.

And the transmission systems designed for use with single mode fiber will typically cost more than 1000. The cladding diameter of single mode and multimode fiber is 125 µm. Multimode fibers are described by their core and cladding diameters. There are different types of fiber optic cable.

Multimode fibers originally came in several sizes optimized for various networks and sources but the data industry standardized on 62 5 core fiber in the mid 80s 62 5 125 fiber has a 62 5 micron core and a 125 micron cladding. And multimode fiber core diameter is 50 µm and 62 5 µm typically which enables it to have higher light gathering ability and simplify connections. Multimode fiber is usually 50 125 and 62 5 125 in construction. The attenuation of multimode fiber is higher than sm fiber because of its larger core diameter.

What s happening inside the multimode fiber. Rf broadband signals such as what cable companies commonly use cannot be transmitted over multimode fiber. Multi mode links can be used for data rates up to 100 gbit s. 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.
