1. KVM extenders

G&D's KVM extenders enable you to operate your computers over IP systems or dedicated distances up to 10,000 m whilst maintaining real-time performance. The systems consist of a transmitter and a receiver module. A local console at the transmitter module placed in the server room makes it easy for the IT staff to maintain the system.

The question of whether to use compressed or uncompressed video transmission often plays a decisive role when selecting KVM equipment for air traffic control rooms.

Uncompressed video transmission: pixel-perfect, latency- and loss-free

G&D’s non-compressing extender systems extend incoming video signals with absolutely no loss. For uncompressed transmission, the systems require a higher bandwidth, which in turn requires more powerful components. The KVM extender DP1.2-VisionXG can be used to extend high-resolution 4K video signals, or even 8K video signals with MC4 versions, at full 60 Hz. The DL-Vision-DP can be used to extend high-resolution 2K video signals, or 4K video signals with MC versions, at full 60 Hz and the DL-Vision extends the dual link DVI video signal.

Compressed video transmission: lower bandwidth and compatible with matrix systems

G&D’s compressing KVM extender systems also guarantee very high video quality and are therefore often used in air traffic control. Thanks to G&D’s compression method High Dynamic Image Processing, level 3, video signals are reproduced pixel-perfect and visually loss- and latency-free – despite a lower bandwidth. One of the key advantages of compressed signals is that they can be processed, extended and switched via a KVM matrix system. The DP1.2-Vision and DP-Vision can be used for the compressed extension of DisplayPort video signals, and DL-DVI-Vision and DVI-Vision for the compressed extension of dual link and single link DVI video signals.

KVM-over-IP extender systems: extend signals by using IP structures

Therefore, G&D now offers you KVM extenders that enable access via IP structures. KVM-over-IP extender systems use G&D’s KVM-over-IP technology to transmit signals. Thus, operators can access the connected computers over IP structures. The transmission is based on IP networks over gigabit Ethernet networks (OSI model layer 3).
