Multimode Fiber Cable Distance

This application is typically used for short distance data and audio video applications in lans.

Multimode fiber cable distance.

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 cable will support 1000base sx out to 275 meters and that distance jumps to 550 meters with om2 cable. Multimode fiber is usually 50 125 and 62 5 125 in construction.

The 62 5 125 µm aka. Multi mode links can be used for data rates up to 100 gbit s. 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. 62 5 125micron known as om1 50 125micron om2 and 50 125micron high bandwidth om3.

There are three types of multimode fiber. When making a decision between single mode and multimode fiber cables the first factor to consider is the fiber distance which you need actually. There are two basic types of transmitters that work with multimode fiber. 850nm led and 1300 nm laser.

Supported speeds can range from 16mbs token ring to 10gbs ethernet. However it s becoming more costly for optical fiber cable to support next generation ethernet speed migration as bandwidth requirements increase. For example in a data center multimode fiber cables are enough for the distance of 300 400 meters. Multimode fiber optic cable has a larger core typically 50 or 62 5 microns that enables multiple light modes to be propagated.

Rf broadband signals such as what cable companies commonly use cannot be transmitted over multimode fiber. The maximum transmission distance for mmf cable is around 550m at the speed of 10git s. Speed gbps maximum distance meters by optical media type. Because of this more data can pass through the multimode fiber core at a given time.

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.
