Distribution frames with dense connectors are often encountered in fiber optic networks. Although this design saves space, once a connector is plugged or unplugged during maintenance, it poses a huge problem for maintenance personnel, especially when it comes to plugging or unplugging small connectors such as the LC type, which is even more complex. The RS-8 fiber connector plugging and unplugging tool can implement connector plugging and unplugging work in a compact space. Almost all square connectors are suitable, including LC, MU, SC, E-2000, MT-RJ, and so on.
