The XDK media converters were specificallydesigned to offer network designers the tools for migration from copper basedGigabit to fiber based Gigabit Ethernet. Now, migration or expansion ofexisting networks can be achieved with minimum cost and complexity. Theconverters are completely transparent when installed so the network performsexactly the way it would do normally-only now, it can migrate both copper andfiber mediums. This flexibility in cabling allows network managers to put fibercables anywhere with in a network without changing the arrangement of copperbased Gigabit segments. Their compact size allows the converter to be easilydeployed in any narrow desktop location or used in wall-mount installation tosave space.
