摘要： The present invention relates to an optical fiber accommodated in an optical fiber cable, and more particularly, to an optical fiber which optimizes optical fiber coating resin and color resin and restrains an increase in transmission loss of the optical fiber due to an operating environment and aged deterioration and provides an optical fiber and optical fiber ribbon without any increase of transmission loss irrespective of the operating environment and aged deterioration, and especially when exposed to water or high humidity.
The optical fiber is an optical fiber coated with at least two layers of coating resin, wherein the outermost coated coating resin is a colored layer made of color resin and when the optical fiber is immersed in water which is heated to 60°C for 168 hours, an extraction rate of the coating resin of the optical fiber is set to 1.5 mass percent or below.摘要翻译： 本发明涉及容纳在光纤电缆中的光纤，更具体地说，涉及一种优化光纤涂层树脂和着色树脂的光纤，并且抑制由于操作环境和老化而导致的光纤的传输损耗的增加 劣化，并且不管操作环境和老化劣化，特别是当暴露于水或高湿度时，提供光纤和光纤带，而不会增加传输损耗。 光纤是涂覆有至少两层涂布树脂的光纤，其中最外涂层涂层树脂是由彩色树脂制成的着色层，当光纤浸入加热至60℃168小时的水中时 ，将光纤的涂布树脂的提取率设定为1.5质量％以下。
