Definition
Optical or glass fibers can be used for many different applications, with the main purpose to transport light over a certain distance. Optical fibers consist mainly of a core with a certain diameter, a cladding, and a coating.
Multi mode optical fibers (MM fibers) are used for applications where it is important to transmit as much light as possible, mostly for illumination purposes. They feature relatively large core diameters, usually in the range of 50 µm up to 1,000 µm. Depending on the wavelength of the light, these diameters allow multiple modes of light to propagate through the fiber.
Due to interference effects, light pulses get distorted when travelling through a MM fiber over longer distances. To avoid this, single mode (SM) fibers or polarization maintaining (PM) fibers are used, especially for applications where the pulse character and shape of the optical signals is essential.
Multi mode fibers have a lot of advantages: Due to higher core diameters, the numerical apertures are higher, and more optical power can be transmitted. This results in easier coupling to different light sources like lamps, LEDs and lasers.
With regard to the distribution of their refractive indices, multi mode fibers can be divided into the two categories of step-index fibers and graded-index fibers:
Step-index Fibers
The core of a step-index fiber shows a uniform refractive index over its entire cross-section. At the boundary between the core and the cladding there is a sharp jump (step) in the refractive index, leading to total reflection of the light at that interface. This causes the light beam to repeatedly cross the axis of the fiber in a zigzag pattern. Due to path length differences, light beams entering the fiber from different angles have different times of travel through the fiber, which leads to modal dispersion or intermodal distortion for multiple modes of light. Therefore, step-index multi mode fibers are more suitable for low transmission speeds and short distances but have advantages in applications with high optical power density.
Graded-index Fibers
At the axis of a graded-index fiber’s core, the refractive index is high and gradually decreases in the core material towards the edge of the core where the value of the refractive index almost equals that of the cladding. Due to this continuous change in the refractive index, the light rays are deflected from the outer regions of the core towards the core axis. A graded-index fiber thus exhibits internal refraction of the light over the core’s cross-section instead of total reflection of the light at the core-cladding interface. As a result, graded-index multi mode fibers show properties such as a high bandwidth, low optical losses or higher bending tolerance. Modal dispersion is significantly reduced, and the graded-index multi mode fiber is thus suitable for transmitting optical signals over longer distances and/or at higher speeds.
To make multi mode fibers usable in harsh environments at higher temperatures, they can be metallized with aluminium or gold coatings according to the customer’s specification. An additional flexible metal tube can protect the fiber and offer more durability in industrial applications.
For enhanced transmission performance and increased damage thresholds, parts of our multi-mode fiber portfolio can be equipped with anti-reflection technologies. In addition to common anti-reflection coatings, a technology based on nano-structures on the surface is available for selected fibers.
Further options include to equip some of the fibers with a broad selection of shaped tips – standard configurations as well as custom designed shapes – or end-caps to achieve higher coupled power into a fiber core by reducing the power density at the air / silica interface.

AFT/SFT Optical Fiber Tapers
Fiber Type Single Mode, Multi Mode Step & Graded Index; Input Core Diameter 100 to 600 µm; Output Core Diameter 50 to 200 µm; Numerical Aperture 0.12, 0.26; Wavelength 180 to 2400 nm; Sheathing PVC, Stainless Steel
Fiberguide’s AFT/SFT series of optical tapers are used for mode mixing, lowering optical power density in high power applications, and converting numerical aperture (NA) in optical power delivery applications. Optical tapers can either be tower drawn, where the length is several meters, or they can be produced using bench-top equipment, making the length a few inches. In both cases, these optical tapers are continuous pieces of fiber, they are not spliced. Tapered optical fibers can be made either by fusing a short tapered section onto a longer fixed diameter fiber or by very carefully controlling the drawing process to produce a single continuous fiber with an integral tapered section. For its AFT/SFT series, Fiberguide uses the latter process since it results in superior fiber strength, alignment precision and optical power transmission. Tapered optical fibers cause optical mode mixing that tends to homogenize spatial power distribution. A larger input core diameter can prevent input damage and allow a smaller diameter pigtail for convenience in adapting to a wide range of optical applications. Tapered optical fibers can be used as a passive optical component to alter the input and / or output divergence (N.A.) with regard to an optical fiber, as a high power coupler for laser energy, as this will spread the energy over a larger area, or simply as a device to relax tolerances in an optical system. To ensure maximum efficiency of light transmission, the numerical aperture (N.A.) of the light entering the taper input should be 0.22 divided by the taper ratio. As an example, assume the input core diameter of the taper is 400 µm and the output core is 200 µm (2:1 taper ratio), then the N.A. of the light entering the taper will be 0.22/2 = 0.11.
Additionally, the fibers can be equipped on demand with Fiberguide’s patented RARe Motheye anti-reflective technology that enhances fiber transmission performance and significantly increases the damage threshold for your application over a large wavelength range. Key Features:

The fiber is then plated with an overcoat layer of gold to provide resistance to oxidization. The result is a strong, uniform coating capable of handling the rigors of soldering and hermetic sealing. OZ Optics metalized fibers are well suited for use in assemblies that must conform to Telcordia requirements. If required, OZ Optics metalized fibers can be manufactured with masked ends. This process provides a clean, non-metalized fiber end suitable for termination with ceramic ferrules, fusion splicing or direct connection to a device and allows for an easy transformation of devices into hermetically sealed packages. Also available are custom mid-span metalization of optical fibers and metalized ribbon fibers. The mid-span configuration provides a solution for hermetically sealing in-fiber devices such as fiber Bragg gratings, optical isolators or optical filters, as well as allowing larger package devices that exceed the length restrictions of standard metalized fibers. Metalization of ribbon fibers allows for easy hermetic sealing of multiple fibers into hermetic packages that require many fibers or are being used with V-Groove assemblies. OZ Optics metalized fibers are available with Single Mode (SM), Multi Mode (MM) or Polarization Maintaining (PM) fibers. In general, OZ Optics uses polarization maintaining fibers based on the PANDA fiber structure when building polarization maintaining components and patch cords. However, OZ Optics can construct devices using other PM fiber structures. OZ Optics also carries some alternative fiber types in stock, please contact AMS Technologies for availability. If necessary, OZ Optics is willing to use customer supplied fibers to build devices. Key Features:

MMF/QMMF/QMMJ Multi Mode Fibers
180-2400 nm; Core Diameter 10-1000 µm; Cladding Diameter 125-1035 µm; Attenuation: ≤0.7-<1000 dB/km; Numerical Aperture 0.10-0.37
OZ Optics offers a wide range of optical fibers suitable for many applications. MMF/QMMF/QMMJ multi mode (MM) fibers come in a variety of fiber sizes, operating wavelengths, and fiber types, and can be assembled into patchcords or more complex fiber optic components to suit your needs. OZ Optics categorizes fibers based on fiber type, operating wavelengths, core/cladding size, jacket diameter, and numerical aperture (NA).
OZ Optics’ MMF/QMMF/QMMJ multi mode fibers have large fiber core sizes and large numerical apertures, making them well suited for collecting light from large or diffuse sources such as LEDs or white light lamps. They are also well suited for high-power applications as the power is transmitted through a large cross section compared to single mode (SM) or polarization maintaining (PM) fibers. The drawback with multi mode fibers is that they do not maintain the high-quality spatial properties of lasers. Instead, the light is dispersed among multi mode modes within the fiber, generating a speckle pattern when the light emerges from the other end of the fiber.
Typically, MMF/QMMF/QMMJ multi mode fibers are suitable either for near infrared and visible wavelengths (IRVIS fibers) or for near ultraviolet and visible wavelengths (UVVIS fibers). UVVIS multi mode fibers typically are built with added amounts of hydroxyl (OH) ions added to enhance ultraviolet transmission at the expense of infrared transmission.
Graded-index multi mode fibers (MMF) have a fiber core with a refractive index that varies from the center to the edge. They are mainly used for telecommunications applications and come in three standard core/cladding sizes: 50/125, 62.5/125, and 100/140.
Step-index silica core (QMMF, QMMJ) fibers have a fiber core with a constant index of refraction. Typically, the fiber core is fused silica, doped with an element like germanium, while the fiber cladding is typically undoped fused silica for fibers with numerical apertures up to 0.22, and typically a hard polymer for higher numerical apertures. These fibers are available with core sizes ranging from 10 µm to 1500 µm, and NAs ranging from 0.12 to 0.5.
