Industrial Grade Ethernet Switch has the feature that up to three ports can be designed with multi-mode glass fibres and while the twisted-pair lines support transmission rates of 10 and 100 mbps, the glass fibre lines are designed for 100 mbps. The Switch has potential free contact. The Switch has electrical isolation of network segments. The Switch has the feature of increasing the network performance by filtering the data traffic, simple network extension and coupling of copper network segment with different transmission rates, since these are automatically detected. The Industrial Grade Ethernet Switch has each copper port establishes a half or full duplex connection at 10 or 100 mbps and has the feature of auto crossing, so that no distinction has to be made between 1:1 and cross-over lines.
