Unibrain CAT5 Repeater-400 FireWire IEEE1394a Repeater More Like This Unibrain's CAT5 Repeater-400 provides a low cost solution for extending the firewire bus by using standard CAT-5e (crossover) or CAT-6 type cables. The transmission speed can reach up to 400 Mbps (Megabits) at a maximum length of 70 meters (roughly 230 feet). Practical and inexpensive in comparison to deploying runs consisting of multiple FireWire repeater hubs and multiple FireWire cables, the CAT5 Repeater-400 is an unmatched solution for extended FireWire 400 applications.

The CAT5 Repeater-400 utilizes the new TSB41BA3B 1394b PHY from Texas Instruments and EqCologic's 1394b to UTP cabling equalizer. It is optimized to create long-haul IEEE 1394b-2002 connections over CAT-5 or CAT-6 at the S400 data rate, but it can also be used at S200 and S100 for DV25/DV50 digital video applications. The kit comes with a pair of CAT5 Repeater400 repeaters and DC +12V power supplies.
