Did You Know?

Multimode fiber is an optical fiber that is designed to carry multiple light modes, each at a slightly different reflection angle within the optical fiber core. Multimode fiber gives you high bandwidth at high speeds over short to medium distances. Light waves are dispersed into numerous paths, or modes, as they travel through the cable's core typically at 850 or 1300nm. Typical multimode fiber core diameters are 50, 62.5, 100um. As the number of light reflections passing through the core increases, this leads to high dispersion and attenuation rate and eventually the quality of the signal is reduced over long distances. Multimode fibers are typically used for short distances, e.g. for audio/video applications in LANs. RF broadband signals, which cable companies commonly use, cannot be transmitted over multimode fibers.

Frequently Asked Questions

While single-mode fibers can only support one mode, multimode fibers can propagate thousands of modes due to the larger size of the core. The number of modes supported by an optical fiber is dependent on the radius of the core, the wavelength, and the index of refraction of the core and the cladding materials.

Multi-Mode Fibers: Versatile Solutions for Short to Medium Distance Data Transmission

Multi-mode fibers are designed to carry multiple light modes simultaneously, making them highly suitable for short to medium distance applications such as local area networks (LANs), data centers, and industrial automation. These fibers typically have larger core diameters, commonly 50 or 62.5 microns, allowing multiple modes to propagate, which simplifies coupling with light sources like LEDs and VCSELs.

FindLight offers a variety of multi-mode fiber products, including radiation-hard multimode fibers that maintain performance even in high-radiation environments such as nuclear facilities, aerospace, or medical equipment. These fibers ensure signal stability and integrity despite harsh conditions.

Another notable product is the power delivery silica core fiber, designed for applications involving high-power laser transmission. These fibers offer excellent optical properties like low attenuation and high damage thresholds, enabling efficient laser energy delivery in industrial cutting, welding, or medical laser systems.

Multi-mode fibers are valued for their cost-effectiveness and ease of installation, especially in environments where ultra-long distances and ultra-high bandwidths are not necessary. They support high data rates over distances up to a few kilometers, making them ideal for intra-building communication.

Choosing the right multi-mode fiber involves considering core size, numerical aperture, attenuation, and environmental factors such as temperature range and mechanical stress tolerance. FindLight’s broad catalog provides fibers optimized for different wavelengths, bandwidths, and operational conditions.
