LINKOH LK4012P8C4F Industrial Switch is a Layer 2+ managed Gigabit Switch that features

8-Port Gigabit RJ45 + 4-Port Gigabit SFP optical port, is specially designed to build a full Gigabit

backbone to transmit reliable and high-speed data in heavy industrial demanding environments

and forward data to remote network through fiber optic cabling. It comes with an IP40 rugged

case. The industrial managed switch provides user-friendly but advanced IPv6/IPv4 management interfaces. It is the best investment for expanding industrial business or upgrading its network

infrastructure.
