AdderLink INFINITY 4000

A high performance dual-head IP KVM matrix solution with support for 5K video and multigigabit Ethernet connectivity.

  • Dual-head 5K, video, audio and USB over a single fiber connection
  • Pixel-perfect image quality
  • Multi-channel digital audio via DisplayPort™
  • Adder’s USB True Emulation for fast switching
  • Backwards compatible with existing ADDERLink INFINITY infrastructure
  • Plug and play


The ADDERLink INFINITY 4000 Series (ALIF4000) is the world’s first dual-head, high performance 5K IP KVM extender over a single fiber.

The ALIF4000 is fully compatible with the existing INFINITY range, and supported by the trusted ADDERLink INFINITY Manager (AIM), the ALIF4000 can be used as a point-to-point extender or easily integrated into a wider matrix system; enabling KVM users to migrate to 5K without the need to rip and replace.

Product Features

  • Dual-head 5K screens over a single link: The ALIF4000 can deliver two 5K screens over a single link.
  • Multigigabit Ethernet support: Multirate (1/2.5/5/10) GbE support enables premium video performance over 5Gb/s copper links using 100m of standard CAT6 cable.
  • Support for 1GbE: Integrated 1GbE ports enable easy delivery of 4K/60 video over ubiquitous 1Gb/s copper links using 100m of standard CAT5e or CAT6 cable.
  • Support for 5K Resolutions: 5K video resolutions supported for high resolution and ultra-wide video applications (5120×1440@60Hz or 5120×2880@30Hz).
  • Backwards compatibility: The ALIF4000 can integrate seamlessly into your existing ADDERLink INFINITY setup, replacing or working in conjunction with your existing ALIF endpoints
  • Digital KVM matrix: By the addition of ADDERLink INFINITY Management system (A.I.M.) you can turn multiple point to point extenders into a matrix system that allows any workstation to connect to any computer connected to the network. See the A.I.M. datasheet for details
  • Audio capability: Multi-channel digital audio, via DisplayPort™, provides a high-quality immersive sound experience.
  • EDID management: The system has intelligent EDID management to either allow the true characteristics of the monitor to be passed back to the computer, or controlled resolutions to be imposed
  • Plug and Play: The ADDERLink INFINITY range is delivered in a zero config state so they work as soon as they are connected, without the need for drivers or software
  • USB True Emulation: USB2.0 enables connection to any USB human interface device from mice and keyboards through to graphics tablets, jog shuttles, joysticks and 3D explorers
