A fiber Optical switch is a high-speed network transmission relay device. It uses fiber optic cables as a transmission medium compared to ordinary switches. The advantages of optical fiber transmission are fast speed and strong anti-interference ability.The optical fiber Ethernet switch is a high-performance managed Layer 2 optical fiber Ethernet access switch. Users can choose all-optical port configuration or hybrid optical port configuration. The access to the fiber medium can be single-mode fiber or multi-mode fiber. The switch can support both remote network management and local management to monitor the working status of the port and set.
