As this display shows, you can have two glass fibers carrying completely different wavelengths of light right next to each other without issue. We’ve featured some other great fiber optic hacks ...

In low-bandwidth applications, fiber optic cable transmits data using one color of light. There’s a way to get more bandwidth out of a fiber optic cable, as [Shahriar] found out while ...

The absorbing of light energy within an optical fiber due to natural impurities in the glass. Absorption and scattering are the main cause of attenuation (signal loss) in an optical fiber.
