Introduction
1
The RUGGEDCOM RMC41 is a 2-port, unmanaged Ethernet switch that provides
both copper-to-fiber media conversion as well as 10 Mbps to 100 Mbps speed
conversion. Specifically designed to operate reliably in electrically and climatically
harsh environments, it is well suited for use in mission critical Ethernet networking
applications.
The RUGGEDCOM RMC41 is packaged in a compact, galvanized steel enclosure that
allows either DIN or panel mounting for efficient use of cabinet space. It has an
integrated power supply with a wide range of voltages for worldwide operability.
An operating temperature range of -40 to 85 °C (-40 to 185 °F) without the use of
internal cooling fans allows it to be placed in almost any location. The RUGGEDCOM
RMC41 is compliant with EMI and environmental standards for utility substations,
industrial manufacturing, process and control and intelligent transportation systems
applications.
The versatility and wide selection of fiber optics allows the RUGGEDCOM RMC41
to be used in a variety of applications. It can be used in place of traditional copper-
to-fiber media converters with the added ability to convert speed from 10Mbps to
100Mbps.
