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).

OFNP (optical fiber nonconductive plenum) cords are for use in plenum areas—the areas between a ceiling and the floor above it—where space is reserved for the circulation of air. They have the highest fire-resistant rating and emit little smoke during combustion.

LSZH (low smoke zero halogen) cords emit low levels of smoke and no gases during a fire, so they’re good for confined spaces. They cannot be used in plenum areas.

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.
