“twister” 7000 Modules

Media conversion provides a cost-effective means of integrating various
types of Ethernet and Fast Ethernet LAN segments.

All “twister” modules provide media conversion with a low bit delay. All
signal activity – including collision detection – is reliably propagated from
one cable medium to the other ensuring accurate data flow across the
network. Maximum segment lengths are supported on either side of the
device. Seamless operation in half-duplex or full-duplex environments
ensures interoperability with Ethernet and Fast Ethernet devices from other
leading network technology providers. This increases the flexibility of
network configurations by ensuring reliable data transmission in multi-
vendor, as well as mixed media, environments.

An extensive line of plug-and-play, hot-swappable “twister” modules
support 10 or 100Mbps operation and provide a variety of connector
combinations for flexibility and adaptability.
