What wavelength should be used in the fiber distribution box
You use 1310nm and 1550nm fiber wavelengths because these points in the optical spectrum offer the lowest signal loss, which means you can transmit data efficiently. 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. Optical transmission windows are specific wavelength ranges where light travels through fiber with minimal attenuation (signal loss) and dispersion (distortion). These low-loss windows are essential for maintaining the performance and reach of fiber optic communication systems. By selecting the. Thus the normal wavelengths are 850, 1300 and 1550 nm.
