CWDM & DWDM Mux/Demux Overview

As we all know, WDM (wavelength-division multiplexing) is a method of multiplexing a number of optical carrier signals onto a single optical fiber by using different wavelengths (colors) of laser light. It enables bidirectional communications over one strand of fiber, as well as multiplication of capacity. In a WDM system, a multiplexer (Mux) is used […]

Two Types of WDM Connectivity – CWDM and DWDM

Intensive needs for great bandwidth availability and data transmission capacity have boosted the use of WDM in telecommunication. WDM (wavelength-division multiplexing) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light. There are two types of WDM : CWDM and DWDM. What’s the […]

Optical Multiplexing for High Speed Communication Systems

Introduction Optical transmission uses pulses of light to transmit information from one place to another through an optical fiber. The light is converted to electromagnetic carrier wave, which is modulated to carry information as the light propagates from one end to another. The development of optical fiber has revolutionized the telecommunications industry. Optical fiber has […]
