2. Overview
2.1 Introduction
A fibre KVM Extender is mainly used to extend the maximum distance between a CPU and
his Keyboard / Monitor / Mouse considerably. In addition, they are indispensable for
installations in electromagnetic hazardous environments (EMI). Normal Keyboard-/ Monitor-
/ Mouse extender cables (and Extender using traditional cables) cannot go so far and EMI
interferences may reduce the maximum distance and/or reliability. Using a ACS1xxA
Extender system, these limitations are past. Remain your CPU in a secure rack cabinet or data
center while accessing from an up to 10.000m remotely located place.
A basic KVM extension system comprises a Local unit (transmitter) and a Remote unit
(receiver). The Local unit connects directly to the computer (or a KVM switch system) using
the supplied cable(s). The user
console (keyboard, mouse and monitor) attaches to the
Remote unit. The Remote and Local units communicate video and data information along the
interconnecting cable (Multimode fibre).

HID Human Interface Devices are units, which are used for human access to
the CPU. They are a USB-device class of its own (e.g. Memory Devices
etc.). Besides of keyboard and mouse also touch screen, light pen,
fingerprint sensor, graphic tablets etc. are HID devices.
