G652 fiber optic cable G653 G655
657 are ITU-T standardized singlemode fiber types used across long-haul, metro, ODN, and FTTH networks. Each fiber type is engineered with different refractive index profiles, dispersion properties, and bending performance to support specific applications—from long-distance. Its characteristic is that the fiber dispersion is very small when the working wavelength is 1300nm, and the system transmission distance is only limited by the loss;. There are seven kinds of optic fiber according to ITU standard: G651, G652, G653, G654, G655, G656, G657; But do you know what is the feature of each kind? How to choose them when you want to design a fiber optic network? Let's begin with the structure of the optic fiber, shown as below: It.
