NGF-741
Gigabit 1000Base-T to SX/LX Converter
The NGF-741 media converters were specifically designed
to offer network designers the tools for migration from
copper based Gigabit to fiber based Gigabit Ethernet. Now,
migration or expansion of existing networks can be achieved
with minimum cost and complexity. The converters are
completely transparent when installed so the network performs
exactly the way it would do normally-only now, it can migrate
both copper and fiber mediums.
This flexibility in cabling allows network managers to put
fiber cables anywhere with in a network without changing the arrangement of copper based Gigabit segments.
Their compact size allows the converter to be easily deployed in any narrow desktop location or used in wallmount installation to save space. Several converters can be simultaneously installed by using the NXF-719
12-slot 19" rack-mount chassis, or NXF-717 4-slot rack-mount converter chassis.
The NGF-741 takes advantage of Gigabit Ethernet technology, suitable for transmission applications of larger
bandwidth like Video, Image, and Voice over IP.
