Wavelength of light in fiber optic communication
Optical fiber primarily uses infrared light, not visible light, due to lower signal attenuation. Common wavelengths are 1310nm and 1550nm, where silica glass fiber has minimal loss (as low as 0. The attenuation of glass optical fiber. Light in optical fiber travels in the near-infrared region, far beyond visible light, and choosing the right transmission wavelengths is fundamental for minimizing loss and maximizing bandwidth. This article delves into why 850, 1310, and 1550 nm are standard, what less-known regimes and tradeoffs. At the heart of this technology lies the concept of wavelength division multiplexing (WDM), which allows multiple light signals, each at a different wavelength (or color), to travel simultaneously through a single optical fiber. Wavelength is very simply a measure of the space between two photons in a solid beam of light. Light behaves as a wave and a particle, a concept known as wave-particle duality.
