光纤通信系统出现降质现象,表现为氢对光纤损耗特性的影响。光纤附加损耗产生的原因,目前有两种不同看法:一种认为涂覆材料含氢,实用光纤处于氢气之中,附加损耗为氢浸入光纤所致;另一种认为附加损耗的因素潜藏于光纤内部。无氢材料涂覆的光纤仍出现附加损耗。以不同的拉丝速度拉制光纤潜藏下不同的感生缺陷,从而引起不同的附加损耗。高速拉丝有利于光纤的长期稳定性。
Optical fiber communication system degradation occurs, the performance of hydrogen on the optical fiber loss characteristics. The reason for the additional loss of optical fiber, there are two different views: one considers the coating material containing hydrogen, the utility of optical fibers in hydrogen, the additional loss due to hydrogen immersion in the fiber caused; the other that the additional loss factor hidden in the optical fiber internal. No loss of hydrogen-coated optical fiber occurs. Drawing different optical defects under different optical fiber draw speeds leads to different additional losses. High-speed drawing is conducive to the long-term stability of optical fiber.
