The optical port is what we usually call an optical board expansion slot that can be inserted into an optical fiber for long-distance data transmission; the Ethernet port is what we often call RJ45 port, that is, the network cable port. There are a few different ways you can determine if your port is fiber or copper: 1. If it has a clear or colored plastic connector, it is likely fiber. Look at the cable: If the cable connected to the port is thin and. We have some server connections which are being checked for moving to a different location. RJ45 ports use copper cables and are the standard for home and small office networks. They come in various form factors such as SFP, SFP+, QSFP+, and XFP. SFP ports support multiple data rates and interfaces, including Gigabit Ethernet, 10 Gigabit Ethernet, Fibre. The optical fiber interface is the physical interface used to connect optical fiber cables. The principle is that the light enters the light-sparse medium from the light-dense medium, resulting in total reflection.
