More fiber options and wide-temp
If you need more fiber ports, or the extra resilience of wide-temp, then the ESW 200 Series is for you. These unmanaged 4, 5, 6, and 8 port Ethernet switches come in 8 different copper, and single and multi-mode fiber port combinations, all with your choice of SC or ST connectors on the fiber ports. Same heavy industrial specs, same features, more possibilities.

Why Wide-Temp matters
We may sit in air conditioned offices, but our equipment doesn’t always. Just by being in a cabinet, your Ethernet switch experiences temperatures 10°C warmer than the surrounding air – more if there are other devices and multiple power supplies inside. Industrial enclosures near motors or drives get even hotter. If the sun hits the enclosure, it can be like the inside of your car on a summer day with the windows up. Even if you don’t work in a steel mill, a wide-temp device can give you extra reliability and peace of mind.
