Multimode Fiber Cable Distance

Because of this more data can pass through the multimode fiber core at a given time.

Multimode fiber cable distance.

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. Multimode fiber distance and bandwidth designed for short distance communication a multimode fiber cable typically allows light signals to travel up to 1 2 miles. Speed gbps maximum distance meters by optical media type. Multimode fiber optic cable has a larger core typically 50 or 62 5 microns that enables multiple light modes to be propagated.

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. 62 5 125micron known as om1 50 125micron om2 and 50 125micron high bandwidth om3. Multimode fiber is usually 50 125 and 62 5 125 in construction. This application is typically used for short distance data and audio video applications in lans.

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. Rf broadband signals such as what cable companies commonly use cannot be transmitted over multimode fiber. For example in a data center multimode fiber cables are enough for the distance of 300 400 meters. Supported speeds can range from 16mbs token ring to 10gbs ethernet.

Om1 cable will support 1000base sx out to 275 meters and that distance jumps to 550 meters with om2 cable. There are three types of multimode fiber. The 62 5 125 µm aka. Since om1 and om2 fiber can not support 25gbps and 40gbps data transmission speeds om3 and om4 were the main choices for multimode fiber to support 25g 40g and 100g ethernet.

The maximum transmission distance for mmf cable is around 550m at the speed of 10git s. Multimode fiber accommodates roughly 1 ghz of bandwidth which is much less than single mode but sufficient for most audio video and data transmissions. Multi mode links can be used for data rates up to 100 gbit s. However it s becoming more costly for optical fiber cable to support next generation ethernet speed migration as bandwidth requirements increase.

There are two basic types of transmitters that work with multimode fiber.
