2. Overview
2.1 Introduction
A CWDM MUX/DEMUX is used, to reduce the number of required fibres for a number of
independent data links. The CWDM MUX/DEMUX Box mixes the signals in different
wavelengths onto a single fiber and splits it again into the original signals at the end of a link.
A basic CWDM MUX/DEMUX system comprises a Local (KVM-Extender) unit, the
CWDM MUX/DEMUX Box and a Remote (KVM-Extender) unit.

) R, G, B, CLOCK in a data stream with up to
3x 1,6 Gbit/sec. Signals are TMDS Level.
PSU

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.
CWDM
Coarse Wavelength Division Multiplexing is a technology which
multiplexes multiple optical carrier signals on a single optical fiber by
using different wavelengths (colours) of laser light to carry different
signals.
