光纤接头 |
ITU-T L.400/L.12建议书规定了单模和多模光纤的拼接,描述了为获得单根光纤或光纤带之间的可靠拼接而应仔细遵循的适当拼接程序。这些程序适用于单根光纤和光纤带(批量拼接)。拼接是光纤网络中的关键点,因为这会极大地影响链路的质量和寿命。事实上,拼接应确保高质量和性能的稳定性。高质量的拼接通常以低拼接损耗为特征,抗拉强度接近纤维验证测试水平。在预期的环境条件下,拼接应在光纤链路的设计寿命期间保持稳定。目前,熔接和机械接合两种技术可用于接合玻璃光纤,两者之间的选择取决于预期的功能性能以及安装和维护方面的考虑。这些拼接设计用于提供永久性连接。这一版ITU-T L.400/L.12建议书修改了以下内容:–光纤拼接的最大衰减取决于对准方法(有源纤芯、有源包层和无源V形槽对准);–机械拼接的最大衰减;–增加了拼接程序的验证,包括光纤拼接的平均和最大衰减(97%的拼接);–删除了附有日本经验的附录;–包含附录二,通过考虑模场直径失配、纤芯-包层同心度和包层直径,显示了不同类型光纤拼接时衰减的增加;–包含附录三,解释了熔接设备中的光纤成像过程。 |
