Multi mode fiber optic cable diagram.

Another type of fiber optic cable is called multi mode. Most applications in which multi mode fiber is used 2 fibers are used wdm is not normally used on multi mode fiber. Each optical fiber in a multi mode cable is about 10 times bigger than one in a single mode cable. In general there are two methods to link optical fibers together.

Multimode fiber optic cable has a large diametral core that allows multiple modes of light to propagate. Multi mode links can be used for data rates up to 100 gbit s. Wholesale fiber optic cable spools are available in a variety of different spool sizes for the dependable transfer of data across both long and short distances at up to 10 gigabyte speeds. There are two types of multimode fibers.

The attenuation of multimode fiber is higher than sm fiber because of its larger core diameter. Ii 3 1 fusion splice the first method is called a fusion splice. This means light beams can travel through the core by following a variety of different paths yellow orange blue and cyan lines in other words in multiple different modes.

Multimode optical fiber with stepped index. Multimode fiber optic cable. As mentioned in the article on the structure of optical fibers the properties of data transmission via a fiber optic depend on the core hence based on the differences in the structure of the core there are three main types of optical fibers. Fibers that carry more than one mode are called multimode fibers.

The following illustration shows the differences between these two types of multimode fibers on refractive index profile a. Because of this the number of light reflections created as the light passes through the core increases creating the ability for more data to pass through at a given time. 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. Due to its high capacity and reliability multi mode optical fiber is mostly used for communication over short distances such as within a building or on a campus.

Multi mode cable has a little bit bigger diameter with a common diameters in the 50 to 100 micron range for the light carry component in the us the most common size is 62 5um. 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 minimum. One type is step index multimode fiber and the other type is graded index multimode fiber. Example of the construction of a multi fiber cable ii 3 connectivity fiber optic links require a method to connect the transmitter to the fiber optic cable and the fiber optic cable to the receiver.
