Transition Networks, has debuted a line of redundant copper to fiber media converters for Fast Ethernet networks. In the event of a failure in the copper or fiber connection, a fully redundant data line is available on the secondary port.

The Transition Networks' Redundant Fast Ethernet Media Converter provides redundant connections of both the copper and fiber interfaces. Each media interface designates a primary and secondary port. If the link on the primary port fails, control elements of the converter will establish link on the secondary port and this port will be used to carry the traffic. The converter is designed so that only one of the four ports is active at a time, so the product does not interfere with the Spanning Tree Protocol. The converter does not need to be re-set to continue to operate in a redundant mode.

"Network down-time is expensive and in some environments, life- threatening," said Cheri Beranek Podzimek, vice president of marketing for Transition Networks. "The Redundant TX to FX Media Converter provides a cost- effective and reliable means to safeguard against downtime caused by problems with the cabling plant."

The Redundant Fast Ethernet Converter maintains supports for Transition's unique user-selectable N-Way Negotiation feature. N-Way Negotiation teams auto negotiation support with a selectable full or half-duplex option. Support for auto negotiation eases installation, as it is not necessary to manually configure devices to which the converter is attached. The selectable duplex switch optimizes performance because excessive collisions are avoided. As a result, Transition Networks is the only media conversion manufacturer that can guarantee compatibility with any 802.3 compliant 10/100 port.

The TX to FX Redundant Media converter is available in both a stand-alone and chassis card version. When deployed as a chassis card in the Conversion Center, an optional redundant power supply provides additional redundancy and network protection.

The Conversion Center is Transition's 16-slot chassis-like design which can convert many networking protocols, including unshielded twisted pair to fiber conversions for Ethernet, Fast Ethernet, ATM, FDDI and Token Ring, as well as single- to multi-mode fiber conversions for these environments as well as Gigabit Ethernet and OC-12.

The Conversion Center is the only media conversion platform that can be managed under HP Openview for HP Unix, Windows NT and Solaris as well as NetView for IBM AIX and Windows NT.

Pricing and Availability

The TX to FX Redundant Media Converter for multi-mode and single-mode fiber list price, starting at $699.
