Multimode fiber (MMF) is a type of optical fiber that was created to carry multiple light rays or modes concurrently, each at a slightly different reflection angle within the fiber core. This ability to carry multiple modes of light simultaneously is achieved through a larger core diameter compared to single-mode fiber (SMF), typically ranging from 50 to 62.5 microns. This larger core permits easier alignment of light sources and connectors, making multimode fiber more cost-effective and easier to work well with for short-distance applications.
One of the key advantages of multimode fiber is its ability to aid high bandwidth over short distances. This causes it to be perfect for used in local area networks (LANs), data centers, and other applications where high data transmission rates are required. MMF is commonly useful for distances around 550 meters using LED-based equipment and around 2 kilometers using laser-based equipment.
Multimode fiber is available in different kinds, each having its own characteristics and performance specifications. The 2 most common types are OM1 and OM2, which are normally used for shorter distances and lower bandwidth applications, and OM3 and OM4, which are made for higher bandwidth applications over longer distances. OM5, also referred to as wideband multimode fiber, is really a newer form of multimode fiber that supports wavelengths between 850 nm and 953 nm, permitting higher data rates over longer distances

When deploying a multimode fiber optic network, it's important to take into account factors such as the type of fiber, the transmission equipment, and the connectors used. Proper installation and maintenance are vital to ensuring optimal performance and reliability. Additionally, as technology continues to evolve, newer standards and technologies such as for example OM5 and wideband multimode fiber are emerging, offering even higher bandwidth and performance capabilities for future-proofing your network infrastructure.
In summary, multimode fiber is just a versatile and cost-effective solution for high-speed data transmission over short to medium distances. Its ability to support multiple modes of light and high bandwidth causes it to be suitable for a wide selection of applications, from LANs and data centers to industrial and military environments. As technology advances, multimode fiber will continue steadily to play an essential role in enabling high-speed communication networks across the world.
