Multi Mode Fiber Optic Cable Diagram

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.

Multi mode fiber optic cable diagram.

In general there are two methods to link optical fibers together. Multimode optical fiber with stepped index. 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 attenuation of multimode fiber is higher than sm fiber because of its larger core diameter.

Most applications in which multi mode fiber is used 2 fibers are used wdm is not normally used on multi mode fiber. Should you require help choosing bulk fiber optic cables for your project please reach out to one of our customer service experts at 888 212 8295. 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. There are two types of multimode fibers.

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. 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. Jump to single mode fiber page. 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. Another type of fiber optic cable is called multi mode. Fibers that carry more than one mode are called multimode fibers. Multimode fiber optic cable has a large diametral core that allows multiple modes of light to propagate.

The following illustration shows the differences between these two types of multimode fibers on refractive index profile a. Ii 3 1 fusion splice the first method is called a fusion splice. 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. One type is step index multimode fiber and the other type is graded index multimode fiber.

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 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. 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. Multi mode links can be used for data rates up to 100 gbit s.
