Shanghai Gengyun Industrial Co., Ltd
G.654.E optical fiber has an extremely low attenuation coefficient. Which makes the power loss of optical signals during transmission very small. Specifically, the attenuation coefficients at 1550nm and 1625nm wavelengths are very low, reaching 0.17dB/km and below 0.19dB/km respectively. Which helps to achieve longer transmission distances without electrical relays. The effective area of G654E optical fiber is relatively large. Which helps to reduce nonlinear effects during optical transmission. Thereby supporting higher-speed optical transmission. The G.654.E fiber optic has good bending performance and can be deployed in various complex environments. Such as land long-distance transmission systems, submarine communication systems,etc.
