Gefen Demonstrates Three New Ways to Extend DVI using Copper or Fiber Optic Cables for Long Distance Signal Extension

(Virtual Press Office) -- Stand 1-M80, Amsterdam, The Netherlands - When it comes to extending high resolution DVI graphics, Gefen offers three new extenders designed to enable a flawless signal extension with 24/7 reliability.

The DVI RS-232 over Fiber Extender is a traditional sender/receiver system that delivers DVI with RS-232 up to 300 meters in distance over a single strand of multi-mode fiber optic cable terminated in SC, which guarantees a signal delivery immune to EMI (electromagnetic interference). Virtual EDID management ensures a constant syncing between source and display with zero signal delays or drop-outs.

The DVI Extender over CAT-6 with Galvanic Isolator delivers DVI resolutions up to 1920x1200 using one CAT-6 cable. It is effective at distances up to 100 meters and uses a sender/receiver system connected to the computer or source and the remote DVI display. An instant delivery of high resolution video is guaranteed. Gefen’s DVI Galvanic Isolator is built-in, providing protection in the immediate area from ground loops that can potentially (in extreme cases) cause system damage and electric shock. Though used primarily in medical imaging scenarios, the Galvanic Isolator allows the use of economical copper cable instead of fiber optics, with similar results at a reduced cost. It provides up to 5kV galvanic isolation between devices, and supports high resolutions up to 1920x1200. Gefen’s Galvanic Isolator can also be purchased as an add-on solution to any existing sender/receiver extension system using CAT-x cabling in a sensitive environment.

The DVI Extender over CAT-5 Short Range Extender offers economical pricing on a shorter range extension. It sends DVI graphics with power using one CAT-5 cable up to 70 meters. Extending power over the same CAT-5 cable as DVI is possible using Gefen POL (Power Over Line) technology, which releases the receiver from requiring a power supply. This solution can streamline installations where an AC plug is limited at the receiving end.
