Unibrain FireWire 400 6-Pin to 4-Pin (i.LINK) Cable | IEEE 1394a S400

Professional FireWire 400 (IEEE 1394a) 6-pin to 4-pin (Sony i.LINK) cable with quad shielding and 110-ohm impedance control for DV/HDV camcorders, audio, and legacy AV equipment.

Unibrain FireWire 400 6-Pin to 4-Pin (i.LINK) Cable | IEEE 1394a S400

Product details

The Unibrain FireWire 400 (IEEE 1394a) 6-pin to 4-pin (i.LINK) cable connects standard 6-pin FireWire 400 host ports on workstations, PCIe adapters, and repeaters to 4-pin FireWire / Sony i.LINK ports found on DV and HDV camcorders, broadcast decks, portable audio gear, and legacy notebooks.

Unibrain’s FireWire cables offer superior signal integrity through better connectors, shielding, and handling:

  • Top-quality connectors with high-density enclosures to eliminate connector-induced noise.
  • Outer shield and inner foil-and-braid quad shielding ensuring compliance with IEEE 1394a S400 standards while suppressing radio-frequency (RFI) and electromagnetic interference (EMI).
  • Careful storage and shipment procedures so performance is not affected by accidental excessive bend radius.

Engineered for Reliable runs up to 10 Meters (33 ft)

Unibrain’s 1394a cables meet TIA/EIA 568-A proposed Category 5E for all parameters except characteristic impedance, which is held to 110 Ohm ± 10% across 100 MHz to 400 MHz, with tight control over skew, attenuation, and crosstalk. This allows safe, drop-free operation at lengths up to 10 meters (32.8 ft)—recommended by Unibrain as the maximum passive operating length for S400 devices and HDV (High Definition) camcorders.
