UPC,即超物理接触,从PC光纤连接器演变而来,其端面抛光性能和表面光洁度更佳,端面呈圆顶状。UPC光纤连接器依赖机器抛光,回波损耗比PC光纤连接器高,约接近-50dB或更高。此外,当使用UPC光纤连接器时,要确保激光器的规格能够处理它所产生的回波损耗。还有一点需要注意的是,反复的连接和断开会导致UPC光纤连接器端面的质...
以FS LC APC单模光纤跳线为例,光纤两端的连接器均为绿色。对于LC UPC单模光纤跳线,连接器通常为蓝色。这也是区分这些连接器的一种简单方法。 图5:LC / UPC VS LC / APC 性能 由于顶点偏移中的气隙,使用APC连接器过去很难实现低插入损耗,但是如今连接器设计的改进和制造上的推动APC连接器的性能更好。APC和UPC...
