Multi Mode Fiber Optic Cable Diagram

One type is step index multimode fiber and the other type is graded index multimode fiber.

Multi mode fiber optic cable diagram.

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. Multi mode links can be used for data rates up to 100 gbit s. 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. Multimode optical fiber with graded index.

Each optical fiber in a multi mode cable is about 10 times bigger than one in a single mode cable. Typical transmission speed and distance limits are 100 mbit s for distances up to 2 km 1 gbit s up to 1000 m and 10 gbit s up to 500 m. In general there are two methods to link optical fibers together. Ii 3 1 fusion splice the first method is called a fusion splice.

Most applications in which multi mode fiber is used 2 fibers are used wdm is not normally used on multi mode fiber. There are two types of multimode fibers. 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. 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.

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. 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. The following illustration shows the differences between these two types of multimode fibers on refractive index profile a. Multimode fiber optic cable.

Fibers that carry more than one mode are called multimode fibers. 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. 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. 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.

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