技术介绍
光纤热缩管是单芯光纤热缩保护套管,单芯光纤热缩保护套管主要用于单芯光纤接续的裸纤部分,内管为热熔管,中间衬加强件,外管为透明的热收缩管。加强件一般为不锈钢捧、石英捧或陶瓷捧。光纤是构成光通信系统的重要组成部分,它提供了光信号传输的通道。光纤通常由纤芯、包层和涂覆层构成。纤芯和包层都是高纯度二氧化硅,由于掺杂剂掺杂的比例不一样,使纤芯的折射率比包层的折射率高,且损耗比包层低,因此光能量主要在纤芯内传输,包层为光的传输提供了反射面和光隔离,并起一定的机械保护作用。在使用光纤热缩管的时候需要将光纤穿过光纤热缩管的热熔管,然后将光纤对接的部位用光纤热缩管包裹住,当加热时,光纤热缩管热熔管熔化,紧紧地包裹住熔接后的光纤接头,达到填充和密封的作用;加强件起到支撑作用和抗拉抗弯作用;热缩管受热收缩,将光纤接头、热熔管和加强件紧紧包裹,形成一个整体,增加光纤接头部分的机械强度,同时防止潮气侵入,从而维持光纤传输性能的长期稳定。现有技术中,存在加强芯容易从热收缩管和热熔管之间掉落, ...
