The Gustard N18 network switch has 2 RJ45 Ethernet ports and 1 SFP optical fiber connector. The RJ45 Ethernet ports are based on the 10/100/1000Base-T and 1000base-X standards, while the SFP port supports GPON/EPON protocols. With this network switch, you can enjoy not only the flexibility of RJ45 connections, but also the stability and transmission speed of optical fiber signals. The latter can be used for longer distance connections.
