VS-4FW, Firewire Repeater / HUB VS4FW VS4-FW



The VS-4FW and VS-8FW are high performance bidirectional hub/repeaters for 6-pin FireWire (IEEE 1394) signals. They will increase the number of ports available and/or will extend the distance of FireWire cable runs.

Typical Applications:

  • Digital video production and editing studios.

  • Digital video live broadcasting.

  • PC Firewire port extension and long cable drive.



  • Cascading Operation - multiple units can be cascaded to create a FireWire system with up to 63 ports

  • Range - Doubles FireWire cable range from 14.75’ (4.5m) to 29.5’ (9m). Multiple units can be cascaded to extend the range to up to 236’ (72m).

  • Hot Swapping - Supports plug and play.

  • Transfer Rates - 100, 200, and 400Mbps.

  • ESD Protection - Incorporates Kramer’s Spark-Guard ProTM signal protection circuitry to help protect against EDS (electrostatic discharge) which can damage digital equipment.

  • Compact Size - Part of the Kramer TOOLS™ family of compact, high quality and cost effectiv solutions
