由于光纤的损耗大，考虑到探测器的灵敏度限制，不宜作长距离传输。
Transmission by ultraviolet fiber is not suitable for long distance considering the great losses and the sensitivity limited of detector.
配合料中引入适量NH_4HF_2，选用温度结构合理的拉丝炉及拉丝工艺也有助于降低光纤的损耗。
Moreover, the NH4HF2 content in the batch, the temperature distribution in the fiber-drawing furnace, and fiber drawing technology also have influence on the scattering loss of the fiber.
自从半导体激光器性能取得重大突破和光纤的损耗得到极大降低之后，光纤通信已进入实用化商业化时代。
Since the semiconductor laser performance obtains a significant breakthrough and the fiber loss decreased enormously, the optical fiber communication entered the practical commercialization times.
