Description

Introduction

Wavelength Division Multiplexer (WDM) is the device which uses multiple optical maser to transmit multi beam of different wavelengths of laser technology through a single fiber. Each signal is transmitted in its unique channel after the data (text, voice, video and so on) modulated. WDM can increase the existing fiber infrastructure for phone companies and other operators.

Wavelength division multiplexing technology as a system concept, there are 3 modes, wavelength division multiplexing at 1310 nm and 1550 nm wavelength, CWDM (Coarse Wavelength Division Multiplexing) and DWDM (Dense Wavelength Division Multiplexing).

Coarse Wavelength Division Multiplexing (CWDM) is a type of optical wavelength management device that are based on proven ultra low-loss thin-film filter (TFF) technology. It features small size, high reliability, high extensibility, simultaneous transmission of multi-wavelength.

CWDM has gained prevalence in multi-wavelength digital transport architectures because it enables the use of very low cost uncooled distributed feedback (DFB) laser transmitters. Moreover, their powering requirements are reduced and reliability is increased.
