Fiber optics is a crafting component in Fallout 4 and Fallout 76.
Characteristics
Thin, flexible fibers made of high-quality glass, used to transmit signals more efficiently than with metal wires. In-game, fiber optics are a key component to high-tier electronic weapon modifications and settlement devices, such as laser turrets.
With the Contraptions Workshop add-on, they can be used to produce energy weapons on the energy weapon forge.

Locations
- 49 can be obtained in the Jamaica Plain Town Hall basement by disarming a large amount of laser tripwires. The tripwires can be reset by pushing a button in the same room for infinite fiber optics, crystals and steel.
- Teagan sells shipments of 25 fiber optics.
- After a peaceful conclusion to the Restoring Order quest from the Automatron add-on, Isabel Cruz sells shipments of 25 fiber optics.
- Alexis Combes occasionally sells shipments of 25 fiber optics. However, her available shipments are not fixed and will cycle periodically among various shipments including ballistic fiber and nuclear material.
- One method to cycle her shipment stock manually is to wait/sleep 48 hours.
- Alternatively, reloading a save made before speaking with her will reset the random shipment.
