NXF-757
10/100Base-TX to 100Base-FX Mini Converter
Product Introduction & Benefits
The NXF-757 series is among VOLKTEK's answers to
expanding existing Fast Ethernet networks. The easy
implementation and expansion of 100Base-TX/FX networks
can be further assured with this converter.
The converter is completely transparent when connected so
the network performs exactly the way it did before - only now,
it allows the co-existence of both copper and fiber mediums.
Added flexibility is available with ST, SC, and WDM Simplex
SC connectors. Extra distances are possible with the single
mode version delivering up to 80km connectivity per
transmitted segment.
The NXF-757 allows the installation of fiber cabling anywhere within a Fast Ethernet network topology by directly
connecting to existing devices. Its compact modular design facilitates deployment in a narrow desktop location to save
space.
