Link Fault Pass-Through (LFPT) is a troubleshooting feature that combines TX and
FX link loss from both the local and remote Compact Media Converter, TX-FX/SFP
modules. LFPT is enabled by turning on the DIP switch on both modules. This
feature allows either end of the conversion to detect a link fault occurring at the
other end of the media conversion chain. On the Compact Media Converter, LFPT
is supported on the connector closest to the DIP switch.
