The Gustard N18 PRO network switch features 5 RJ45 Ethernet ports as well as an SFP fiber optic connector and a BNC connector for external 10Mhz clock. The RJ45 Ethernet ports are based on 10/100/1000Base-T and 1000base-X standards, while the SFP port supports GPON/EPON protocols. With this network switch from Gustard, you can enjoy the flexibility of RJ45 connections, but also the stability and transmission speed of a fiber optic signal. The latter can be used to connect over longer distances.
