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.
Made of borosilicate glass, the fibers resist greater heat and transmit light better than plastic fibers. 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.
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. Choose fiber bundles with 0.66 NA for general purpose illumination. Fiber bundles with 0.55 NA cover a smaller area than those with 0.66 NA, making them good for lighting angles that have less space.

Fiber-Optic Cords
Connect computers, servers, and switches in a fiber-optic network.
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 (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.
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.
Cords with SC connections have push-pull connectors that lock in place with a tab.
Cords with ST connections have twist-lock spring-loaded connectors that secure in place with a bayonet lock.
