Yes, switches have IP addresses just like any other device on a network. An all-optical Ethernet switch is a network switch whose service ports are entirely optical, meaning every interface uses fiber rather than copper. This design enables end-to-end optical signal transmission, avoiding the conversion between electrical and optical signals at the switch port level. A switch operates at the data link layer (Layer 2) and forwards data based on MAC addresses. They can function as core, aggregation, and access devices on campus networks and connect to upstream and downstream devices. A passive optical network (PON) or Gigabit Passive Optical Network (GPON) is a point-to-multipoint (P2MP) network that uses a combination of active transmission equipments and passive cable components to provide network connectivity to end user's devices.
