Advantages of Gradient Index Multimode Optical Fibers
Gradient index (GI) multimode optical fibers are designed with a refractive index profile that gradually decreases from the fiber core center toward the cladding. This structure helps reduce modal dispersion by allowing different propagation modes to travel at more similar effective velocities, resulting in improved bandwidth performance and signal integrity compared to conventional step-index multimode fibers. FiberTech Ultrasol GI multimode fibers are optimized for VIS-IR optical transmission applications requiring efficient light coupling, stable signal propagation, and reliable performance across industrial communication, sensing, spectroscopy, and photonics systems.

High-Bandwidth VIS-IR Transmission Performance
FiberTech Ultrasol gradient index multimode fibers are engineered to support high-bandwidth optical transmission at both 850 nm and 1300 nm wavelengths. The optimized refractive index profile minimizes modal dispersion, enabling improved signal integrity and enhanced data transmission performance in industrial communication, sensing, and photonics applications. Multiple core diameter options are available to support efficient optical coupling and system integration across a wide range of VIS-IR optical platforms.

Multiple Core Diameter Options for System Integration
FiberTech Ultrasol multimode fibers are available in a wide range of core diameters from 50 µm to 600 µm, enabling optimized optical coupling for communication systems, spectroscopy instruments, sensing platforms, and laser delivery applications. Larger core diameters provide improved alignment tolerance and higher optical throughput, while smaller cores support higher bandwidth transmission performance in data communication and photonics systems.

Frequently Asked Questions

What kind of connectors do LEONI laser cables have?

LEONI offers a variety of different laser cables with F-SMA/SMA905 connectors, depending on the beam power levels. All SMA connectors have a free-standing fiber tip. CuSMA cables with their distinctive copper alloy ferrule and excellent fiber alignment provide good heat removal and fiber centration. The CuFC connectors provide a connector interface for FC-style applications.

What is the advantage of using graded-index fibers for laser beam transmission?

The light rays within graded-index fibers will not follow a zigzag-path as in the case of a step-index profile. The fiber acts as a lens duct with the advantage that the input NA and the beam diameter at the fiber input will be preserved.

What kind of laser systems are LEONI laser cables suitable for?

LEONI laser cables are specially designed for transferring laser beam energy generated by industrial and medical laser systems, including high-power semiconductor lasers, solid-state lasers, and fiber lasers.

What is the difference between graded-index fibers and step-index fibers?

Due to the doping of the fiber core graded-index fibers have a lower laser damage threshold and a higher numerical aperture in comparison with step-index fibers.

What is the Business Unit Fiber Optics?

The Business Unit Fiber Optics is a leading producer of high-quality multimode fibers with graded index profile used for data transmission.

What is a gradient index multimode fiber?

A gradient index multimode fiber uses a gradually changing refractive index profile to reduce modal dispersion and improve bandwidth performance compared to step-index multimode fibers.
