The SDW-541-F1G-T4G is an unmanaged 5 port switch with one SFP fibre port supporting 100 Mbit/s or Gbit Ethernet, and four copper ports supporting 10/100 Mbit/s or Gbit Ethernet. It is designed for easy use in heavy duty industrial, maritime and rail trackside applications. The unit supports 802.1Q long packets which allow all standard industrial Ethernet protocols to be used.

The Westermo range of 100Mbit or Gbit Small Form-factor Pluggable (SFP) transceivers are available as multimode, singlemode or Bi-Di transceivers with distance up to 120 km.

The SDW-541-F1G-T4G is designed for use in industrial applications with dual 9.6 to 57.6 VDC power input. The unique “tri-galvanic” isolation provides isolation between all ports, power supply and between each chassis screen avoiding ground loop currents.

The IP21 rating ensures that the unit can be installed in locations where condensed water may occur.

Only industrial grade components are used which gives the SDW-541-F1G-T4G an MTBF of 1.182.000 hours and ensures a long service life. A wide operating temperature range of –40 to +74 °C (–40 to +165 °F) can be achieved with no moving parts.

The SDW-541-F1G-T4G has been tested both by Westermo and external test houses to meet EMC, isolation, vibration and shock standards, all to the highest levels suitable for heavy industrial, trackside and maritime environments.

Network diagnostics are simplified with the inclusion of port mirroring on one port allowing data flow through the switch to be monitored using a network analyzer. All five ports can have data rate and flow control locked by DIP switches which can eliminate problems with old legacy Ethernet equipment that is unable to support auto negotiation.
