Illuminating Glass Fiber Bundles

Light up small and hard-to-reach areas. These bundles are often used in fiberscopes and borescopes. They’re also good for lighting small areas in models, prototypes, and circuit boards. They transmit all colors of visible light and some wavelengths of infrared light.

For precise lighting, they have two layers—the outer layer keeps light contained within the inner glass core. Bundles with a larger diameter have more fibers, so they give off more light.

A separate light source is needed to illuminate them. Connect them to an LED strip or other light source using heat-shrink tubing or a fitted part, such as a ferrule. They’re not for use in telecommunication cables.

0.55 Numerical Aperture—Fiber bundles with 0.55 numerical aperture cover a smaller area than those with 0.66 numerical aperture, making them good for lighting angles that have less space.

0.66 Numerical Aperture—Choose fiber bundles with 0.66 numerical aperture for general purpose illumination.

Borosilicate Glass—Made of borosilicate glass, the fibers resist greater heat and transmit light better than plastic fibers.

Numerical Aperture—The numerical aperture describes the maximum angle of light each fiber accepts and emits. To send light efficiently, use a light source with an angle at or below the numerical aperture.

Fiber-Optic Cords

Connect computers, servers, and switches in a fiber-optic network.

LC Plug × LC Plug

Cords with LC connections have push-pull connectors that lock in place with a latch. Their connectors are about half the size of SC and ST connectors, so they’re best for devices in tight spaces as well as crowded racks and panels.

Multimode OM1 Cable and Multimode OM4 Cable—Multimode cords are often used for shorter runs within buildings. OM1 cords support 10 Gigabit Ethernet at lengths up to 33 meters. They are used for Local Area Networks (LAN).

OFNR Cable—OFNR (optical fiber nonconductive riser) cords prevent the spread of fire from floor to floor within buildings. Use them in vertical spaces, such as shafts, between floors. They cannot be installed in plenum areas. These cords are corrosion resistant. They release heavy black smoke, hydrochloric acid, and other toxic gases when they burn.
