*This product has been discontinued

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 at maximum length of 70 meters (~ 230 ft).

CAT5 Repeater-400™ is using the new TSB41BA3D 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.


  • Two (2) 1394a (Firewire 400) 6 pin ports operating at 100/200/400 Megabits per Second (Mbits/s)
  • One (1) UTP RJ45 port.
  • DC Power connector: Walkman-type 2.0 mm DC Jack (Power supply adapter included with kit)
  • Power Input Range: DC 8V~30V, max. 1.35A.
  • Power consumption (at 12V DC): 0.25 W
  • Full Duplex Data Rate at 100/200/400 Mbps.
  • Fully Interoperable With Firewire, SB1394, and i.LINK Implementation of IEEE Std 1394.
  • Operating temperature: 0′ – 60′ C.
  • Mechanical dimensions: 112 x 62 x 22 mm (or 112 x 72 x 22 mm, including the firewire ports).

 Typical Equalization Performance 

1394 Speed UTP Cable Type
S100 70 m 70 m
S200 70 m 70 m
S400 70 m 70 m

Hardware/Software Support

Any system equipped with Firewire ports. Devices supported: IIDC firewire cameras, SBP2 hard drives, DV camcorders, Firewire networking.

  • Windows support: XP/2003/Vista/7/8, using Unibrain ubCore 1394b drivers.
    Note that with native Windows XP/Vista 1394 drivers performance may be degraded as Microsoft does not support the 1394b standard, yet.
