SFP (Small Form-factor Pluggable) transceivers do not have a MAC address. The MAC address is assigned to the network interface controller (NIC) or network adapter, which is the hardware component responsible for connecting a device to a network.
The SFP transceiver is a hot-swappable input/output device that plugs into a port on a network switch, router, or other networking devices and allows the device to transmit and receive data over fiber optic or copper cables. The SFP port to which the SFP transceiver is connected is typically assigned a unique MAC address by the device manufacturer.
Therefore, the MAC address belongs to the device’s network interface using the SFP port, not the SFP transceiver itself.
