NGF-762A Gigabit Triple-Speed Converter
10/100/1000 to 1000SX/LX (SFP) Converter
Product Introduction & Benefits
The NGF-762A media converter is specifically designed to
offer fiber advantages for mission-critical networks like
Telco/ISP backbones, cable operators, banking and
enterprise networks. The NGF-762A can reduce network
downtime and increase Quality of Service levels. The
converters are completely transparent when installed, so
the network performs exactly the way it would do
normally – only now, it can incorporate both copper and
fiber mediums.
This flexibility in cabling allows network managers to put
fiber cables anywhere within a network without changing
the arrangement of the copper-based Gigabit segments.
Their
compact
size
allows
the
converters
to
be
wall-mounted to save space. Several converters can be
simultaneously installed by using the NXF-717 4-slot and
NXF-719 12-slot, 19" rack-mountable chasses.
The NGF-762A takes advantage of intelligent connection
technology to support Auto-negotiation, thereby eliminating
the hassle of manually configuring or monitoring settings.
This ensures plug-n-play operability.
