Unmanaged Media Converter and Managed Media Converter
An unmanaged media converter simply allows devices to communicate, and does not provide the same level of monitoring, fault detection and configuration as equivalent managed media converters. Connect the devices to the unmanaged media converter and they usually communicate automatically. Unmanaged media converters are simple to use and install. For most unmanaged converters, minimal configuration is required.
A managed media converter is typically more costly than an unmanaged media converter; however, a managed converter provides additional network monitoring, fault detection and remote configuration functionality not available with an unmanaged media converter.
