Multimode Fiber Specifications Distance

Multimode fiber is usually 50 125 and 62 5 125 in construction.

Multimode fiber specifications distance.

This application is typically used for short distance data and audio video applications in lans. Let s take a closer look at the types of multimode fiber options based on bandwidth and distance needs 1 gb s networksthe majority of enterprise fiber networks today still run 1000base sx delivering up to 1 gb s over multimode. 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 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.

Om1 has been the most popular multimode fiber choice throughout the 80 s 90 s and into the early 2000 s and was the most common multimode fiber used and yet it has the lowest data carrying capacity and shortest distance limitations as compared with other multimode fiber types. Not included are many proprietary designs. The 62 5 125 µm aka. Om1 cable will support 1000base sx out to 275 meters and that distance jumps to 550 meters with om2 cable.

It is estimated that the transmission costs of multimode fiber including both transmitter and receiver sides will be in the range of 500 to 800. The 1000base sx sfp compatible with the ieee 802 3z 1000base sx standard operates on legacy 50 μm multimode fiber links up to 550 m and on 62 5 μm fiber distributed data interface fddi grade multimode fibers up to 220 m. Per current standards and specs maximum supportable distances and attenuation for optical fiber applications by fiber type. The article will compare these four kinds of fibers from the side of core size bandwidth data rate distance color and optical source in details.

Designs under development are listed below. Multimode fiber is provided with the core diameter from 50 µm to 100 µm. It can support up to 1km over laser optimized 50 μm multimode fiber cable. Rf broadband signals such as what cable companies commonly use cannot be transmitted over multimode fiber.

Of course these four types of multimode fiber have different specifications as shown in the following table. 1000base sx sfp for multimode fiber only. And the transmission systems designed for use with single mode fiber will typically cost more than 1000. Single mode fiber and multimode fiber are not compatible.
