Multi Mode Fiber Optic Cable

Multimode fiber mmf is a kind of optical fiber mostly used in communication over short distances for example inside a building or for the campus.

Multi mode fiber optic cable.

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. 9 125 single mode fiber simplex 50 125 om3 multimode fiber. The light traveling through a multi mode fiber optic cable may behave in two different ways depending on the design of the cable. Most applications in which multi mode fiber is used 2 fibers are used wdm is not normally used on multi mode fiber.

Jump to single mode fiber page. Multimode fiber optic cable has a larger core typically 50 or 62 5 microns that enables multiple light modes to be propagated. Pof is a newer plastic based cable which promises performance similar to glass cable on very short runs but at a lower cost. Attenuation at 850 nm.

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. What is multi mode fiber optic cable. Single mode fiber optic cable has a small diametral core that allows only one mode of light to propagate. The core size for multi mode cables is between 50 μm and 62 5 μm and the wavelengths are between 850 nm and 1 300 nm.

Single mode fiber optic cable. Multi mode fiber uses a light emitting diode led as its light source. Multimode cable is made of glass fibers with common diameters in the 50 to 100 micron range for the light carry component the most common size is 62 5. 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.
