Single Mode And Multimode Optical Fiber

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 and multimode optical fiber.

Single mode cables are designed to carry light directly down the fiber. 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. When building a 1g fiber optic network that you want to be able to go to 10g or faster on eventually the savings on cost of fiber for single mode saves about half price. This is because it is the optics that dominates the total cost of a network system.

Because it has one mode of transmission it will propagate 1310 or 1550 nm. Because of this the number of light reflections created as the light passes through the core decreases lowering attenuation and creating the ability for the signal to travel further. How the wave is distributed in. Multi mode links can be used for data rates up to 100 gbit s.

These modes define the way the wave travels through space i e. In fiber optic communication a single mode optical fiber smf is an optical fiber designed to carry only a single mode of light the transverse mode modes are the possible solutions of the helmholtz equation for waves which is obtained by combining maxwell s equations and the boundary conditions. What is the difference between multimode and single mode fiber optic cables. Single mode optical fiber often costs less than multimode fiber.

It is a single strand of glass fiber and has a diameter of 8 5 10 microns.
