GLSUN Optical Switch

Fiber optic network switch, or fiber switch, is a multi-port telecommunication network bridge device to connect multiple optic fibers to each other and controls data packets routing between inputs and outputs. More exactly, a fiber optic network switch receives a message from any device connected to it and then transmits the message only to the device for which the message was meant. This makes the fiber optic switch a more intelligent device than a hub (which receives a message and then transmits it to all the other devices on its network). The fiber Ethernet switch plays an integral part in most modern Ethernet local area networks (LANs). Mid-to-large sized LANs contain a number of linked managed switches.  https://www.glsunmall.com/product/fsw-d2x2b-optical-switch.html
