## Long description

AdderLink Infinity (ALIF) dual 2020 (ALIF2020T-IEC) is an IP-based high-performance KVM extender that enables placement of critical computing hardware in a secure, temperature-controlled location while delivering a pixel-perfect desktop experience to the user workstation. The unit supports 4K digital video, USB 2.0 device connectivity and can operate over CATx or fibre links with distances up to 20 km when using appropriate transceivers.
Advantages
The AdderLink Infinity uses spatially-lossless encoding with 1:1 pixel mapping to provide pixel-perfect, colour-accurate video with no artefacts. It supports single-cable CATx or fibre connections for immunity to interference and offers scalable extension distances via standard 1GbE network devices or SFP fibre transceivers. USB 2.0 with class control permits connection of HID and mass-storage devices with the option to restrict non-HID devices for increased security. Intelligent EDID management and plug-and-play zero-configuration operation simplify setup, while redundant network operation enhances reliability. The unit also includes a Magic Eye feature to support dithered video from GPUs such as MacPro cards without degrading link performance.
Suitable for
Secure remote workstation access in broadcast, control room or industrial environments
Placing servers and workstations in temperature-controlled data rooms away from users
Applications requiring pixel-perfect 4K video and low-latency USB device control
Installations needing long-distance links over fibre (up to 20 km with appropriate SFPs)
Key specifications
Model: ALIF2020T-IEC (AdderLink Infinity dual 2020)
Video: Pixel-perfect digital video, supports 4K resolutions
USB: USB 2.0 with class control (HID and optional mass storage control)

How to use
Connect the transmitter to the source computer and the receiver to the user workstation displays, keyboard and mouse. Choose CATx for short structured-cable runs or install suitable SFP fibre transceivers for extended distances up to 20 km. Power the units and they will operate in a zero-config plug-and-play mode; no drivers are required. Use the device class control settings to allow or restrict USB device types as needed, and rely on EDID management to pass monitor characteristics back to the host for correct video output.
Usage recommendations
Use approved SFP transceivers and quality structured cabling to achieve reliable long-distance links; enable USB device class restrictions in high-security environments to prevent use of unauthorised storage devices.
