Multi Mode Fiber
Multi-mode fiber is a type of fiber optic cable which is thick enough for light to follow several paths through the code.
Multi-mode fiber is best suited for use in short lengths, such as those used in Local Area Networks (LANs) and Storage Area Networks (SANs).
Multi-mode fiber comes in two standard widths, 62.5 micron and 50 micron. A micron is one millionth of a meter.
62.5 micron multi-mode fiber can support Gigabit Ethernet over distances as long as 275 meters; 50 micron multi-mode fiber can increase that range to 550 meters
The opposite of multi-mode fiber is single-mode fiber. Multi-mode fiber is easier to work with than single-mode fiber. The fiber is larger and the tolerances required are much lower. The equipment implemented for communications via multi-mode fiber is much less expensive than that for single-mode fiber. Standards-compliant model such as Centralized Cabling presents consumers the ability to clinch the distance adequacy of fiber by unifying electronics in telecommunications rooms, rather than having active equipments on each floor in a building. The fiber’s jacket color is at times used to differentiate multi-mode fibers (orange) from single-mode (yellow) fibers. But the fiber’s jacket colors cannot always be relied upon to differentiate between types of cable.
Multi-mode fiber is sometimes abbreviated as MMF.

- Single Mode Fiber
A single mode fiber is a fiber optical cable that uses only one ray of light known as a “mode”. A single mode fiber can be used to transfer data in either direction at incredibly fast speeds and may stretch along hundreds or even thousands of kilometers. These factors allow single mode fibers to provide [...]...
- How Fiber Optic Cables Work
There are two main types of fiber optic cable, which are single mode and multi-mode. Single mode: Single mode fiber optic cable is a narrow strand that only has one mode of transmission. Single mode fibers are able to transmit at high speeds over long distances as a result of their small core. Because single [...]...
- Fiber Optics
Fiber optic technology makes use of light to carry digital signals via optical cables. Fiber optic cables are very thin glass wires made from extremely pure optical glass. This technology is based on the concept of light reflection. In the case of fiber optics technology, light carrying digital signals is reflected inside the optical cable [...]...
- FC Connectors
The FC connector is a fiber optic connector with a threaded body which was designed for use in high-vibration environments. It is widely used with both single-mode and multi-mode fiber. The fiber’s ending point is implanted in a 2.5 mm ferrule (metal cap or band placed on a wooden pole to avoid splitting) made of [...]...
- MTRJ Connectors
An MTRJ connector is a type of fiber optic cable that has an endpoint similar to the RJ-45 connector endpoint found in Ethernet connections. MTRJ connectors are designed to snap into the Ethernet port of a computer, modem, or wireless router and provide that computer or network with extremely fast data transfer rates. MTRJ connectors [...]...
