Cable splicing is the process of joining two or more lengths of electrical or communication cables together. This technique is commonly used to repair damaged cables or to extend their length. Splicing ensures that the electrical signals can flow seamlessly between the connected cables, maintaining the integrity of the connection. There are different methods of cable splicing, including mechanical splicing and fusion splicing. Mechanical splicing involves aligning the cable ends and securing them with a connector, while fusion splicing uses heat to melt the cable ends together. Both methods are essential in industries like telecommunications and electrical engineering.
