摘　　要：不锈钢管光纤单元作为光纤复合架空地线(OPGW)、海底光缆等特种光缆的通信介质,其光纤附加衰减的大小直接影响着光缆的光信号传输性能。从光纤着色、光单元生产过程和纤膏粘度三个方面分析了各个过程中产生光纤附加衰减的原因及相应的解决办法。提出的光纤单元衰减控制方法在光缆生产时已得到验证,光纤单元的光纤附加衰减能够得到有效控制。The stainless steel tube optical fiber unit is used as the communication medium for optical fiber composite overhead ground wires （OPGW）, submarine fiber optic cable and other special fiber optic cables, the additional attenuation of optical fiber directly affects the optical signal transmission performance of optical cable. This paper analyzes the causes of the additional attenuation of the optical fiber in each process and the corresponding solutions from three aspects： optical fiber coloring, light cell production process, and the viscosity of the fiber paste. The paper proposes the optical fiber unit attenuation control methods, which are verified in the production of optical fiber cable and the result is shown that the fiber additional attenuation of the optical fiber unit can be effectively contronlled.
