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.

2.2 Glossary

The following terms are used in this guide:

Singlemode

9µ Singlemode-fiber cable

Multimode

62,5µ Multimode- or
50µ Multimode-fiber cable

KVM

Keyboard, Video and Mouse.

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.
