4. Functions

This chapter describes some advanced functions provided by the media converter.

4.1 Converter Function

Media Conversion
The device supports the following data conversions between fiber cable and twisted-pair Cat.5 (copper) cable:
The data rate on twisted-pair segment depends on the link speed finally established with the link partner.

4.2 Link Fault Pass Through Function

When the Link Fault Pass Through (LFPT) function is enabled and the media converter detects a link fault on
one port segment, it will force the other port segment link down. It looks like that a link fault is passed from
one port to the other.
The following example illustrates a link fault occurs on the fiber cable (any one cable in a duplex fiber
connection). The link fault is forwarded to both copper link partners finally by LFPT operation of two media
converters.
Both Ethernet devices will also detect a link fault on each Cat.5 connection, although the real fault occurs on
the fiber connection exactly.
