KVM Basics – What are KVM extenders?

FAQs KVM extendersIn many working environments, noisy computers distract employees and take large parts of the often little space. That’s why it’s useful to remove computers to remote, access-protected server rooms. But how do you access your files and data without computers at your desk? That’s where KVM extenders come in handy.

What are KVM extenders?

As the name suggests, KVM extenders extend computer signals. The systems consist of a transmitter and a receiver. Connected to the computer’s standard interfaces and placed in remote server rooms, the transmitter forwards keyboard, video and mouse signals to the receiver placed at the desk. Transmitter and receiver are placed apart from each other in two different locations. Both units are connected via existing CAT cables of fibre optics. In addition to keyboard, video and mouse signals most devices transmit other signals as well.

Those among you who work in broadcasting know that computers in this industry require high performance. But  computers with high performance cause heat and fan noises. They also take away lots of  valuable space. Of course that’s distracting especially when certain tasks demand maximum concentration. A working environment without computers provides you with the following advantages:

  • More space in cramped confines (OB vans, studios)
  • Highest concentration without fan noise, heat and radiations from computers at desks
  • Reduced energy costs for peripherals and air conditioning
  • Computers in a central server room are easier to maintain
  • Maintenance doesn’t distract employees
  • Expensive equipment placed in access-protected server room

Since KVM extenders are hardware solutions, there are no costs for additional software.
