用于光纤对接光纤或光纤对接尾纤，这个就相当于做接头，（光纤对接尾纤是指光纤与尾纤的纤芯对接而不是前者说的尾纤头），用于这种冷接续的东西叫做光纤冷接子。光纤冷接子是两根尾纤对接时使用的，它内部的主要部件就是一个精密的v型槽，在两根尾纤拨纤之后利用冷接子来实现两根尾纤的对接。他操作起来更简单快速，比用熔接机熔接省时间。冷接一般会有两种形式:第一成端的现场快速链接器;第二种光纤对接的冷接子。
For fiber splicing or fiber splicing pigtail, this is equivalent to making joints (fiber splicing pigtail refers to the core splicing of fiber and pigtail rather than the pigtail head of the former). What is used for this kind of cold splicing is called fiber cold splicing. The cold splicer is used when two pigtails are connected. The main part of the cold splicer is a precise V-groove. After two pigtails are pulled, the cold splicer is used to realize the connection of two pigtails. It's easier and faster to operate, saving time than using a welding machine. Generally, there are two types of cold connection: the first is a field quick linker, and the second is a cold connector for optical fiber butt joint.
