  • The difference between switches and routers and optical module collocation solutions
    The difference between switches and routers and optical module collocation solutions
    • May 25. 2021

    We all know that a switch is a network device used to forward electrical (optical) signals, while a router is a hardware device that connects two or more networks. It acts as a gateway between networks and reads the data in each packet. The address then determines how to transmit the dedicated intelligent network device. Next, ETU-LINK will give you a detailed introduction to the differences ...
