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.
