Multimode Fiber Cable Distance

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.

Multimode fiber cable distance.

When making a decision between single mode and multimode fiber cables the first factor to consider is the fiber distance which you need actually. Rf broadband signals such as what cable companies commonly use cannot be transmitted over multimode fiber. Multimode fiber accommodates roughly 1 ghz of bandwidth which is much less than single mode but sufficient for most audio video and data transmissions. Om1 cable will support 1000base sx out to 275 meters and that distance jumps to 550 meters with om2 cable.

However it s becoming more costly for optical fiber cable to support next generation ethernet speed migration as bandwidth requirements increase. 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. Speed gbps maximum distance meters by optical media type. 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. 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. Multimode fiber optic cable has a larger core typically 50 or 62 5 microns that enables multiple light modes to be propagated. There are three types of multimode fiber.

This application is typically used for short distance data and audio video applications in lans. Supported speeds can range from 16mbs token ring to 10gbs ethernet. Multi mode links can be used for data rates up to 100 gbit s. 850nm led and 1300 nm laser.

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 62 5 125 µm aka. 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. There are two basic types of transmitters that work with multimode 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.
