ServSwitch DVI/VGA Fiber Extender, Single-Mode  

Use a PS/2 keyboard and mouse to access VGA and DVI-I equipment locally or remotely over a 2-strand single-mode fiber link using SC® connectors.


Extended Double Diamond™ Warranty Available (3 Additional Year)

Product Highlights

  • Extend PS/2 computers with just one PS/2 keyboard, one PS/2 mouse, and one DVI or VGA monitor.
  • Resolution up to 1600 x 1200.
  • Perfect image quality even at single-mode’s maximum distance of 6.2 miles (10 km).
  • Ideal for air traffic control systems, passenger information systems, and co-locating a user’s computers in a call center. You can also place these extenders in industrial settings.

  • Further Details

  • Combine VGA and DVI video in your extension applications.
  • Access VGA and DVI equipment locally and remotely.
  • On-screen display enables easy video adjustments.
  • Flexible architecture is ready for future changes—and you can download the latest firmware upgrades into the unit’s Flash ROM.

  • With flat-panel displays becoming more popular, you need an extender that can drive DVI or VGA video signals over fiber optic cables—and that’s exactly what our ServSwitch™ DVI/VGA Fiber Extenders do. They support DVI extension with resolutions up to 1600 x 1200 at distances up to 6.2 miles (10 km) over single-mode fiber.

    The DVI/VGA Fiber Extender also supports traditional analog VGA as well, so you can mix DVI and VGA equipment in your application. If you use VGA equipment today but plan to upgrade to DVI in the near future, this extender is ready for the changeover. Our DVI/VGA Fiber Extender also includes Flash ROM memory, so you can download the latest software enhancements from our FTP site.

    You can have your server locked up in a safe, secure room and have access to it from your remote workstation. With its on-screen display, the extender makes adjusting your video a simple matter.

    A multimode model is also available (ACS253A-MM).

    This extender is perfect for KVM extension applications that demand exceptional image quality.

    For DVI/VGA combinations over UTP, check out our ServSwitch DVI/VGA CATx Extender (ACS253A-CT).
