  • What does fiber optic splicing switching mean

    What does fiber optic splicing switching mean

    To begin, the standard definition of splicing in optical fiber is joining two fiber optic cables together. This technique ensures high-performance data transmission and is essential in extending cable runs, repairing broken links, or establishing new network paths in data. What is Fiber Optic Splicing and Why is it Needed? First, let us understand the meaning of the term “splice”. According to Cambridge Dictionary, to splice means to “join the ends of something so that they become one piece. For network managers and technicians, a poor splice can lead to significant signal degradation, network downtime, and costly troubleshooting.
