Product Description


The N-net NT-IN312S-20 is an Industrial Ethernet Switch with 1Fiber and 2RJ45 port, is designed to convert Ethernet networks to fiber networks by transparently converting

Ethernet signals to optic signals. It will extend transmission distance of network to 20Km via fiber port, and the UTP port can support 100 to 250 meters transmission at 10M, 100M,1000M

application, PoE optional. It provides an integrated power supply with a wide range of voltages for worldwide operation, it also offers dual 12~48 VDC power inputs redundant.
