What Are The Differences between SONET,SDH and DWDM?

When compared with traditional SONET or SDH, the next generation of DWDM (Dense Wavelength Division Multiplexing) is seen as a simple architecture with high scalability, capacity add/drop, multiple ring terminations, multi-services, and multiple fabrics. Then, on comparison of SONET vs SDH vs DWDM, what are their differences exactly?   SONET [ Continue reading…]

Introduction of 18 Channel CWDM Mux/Demux for 10G Network

Imagine turning a cottage into a majestic skyscraper without any innovation or construction. This is what Wavelength-Division Multiplexing (WDM) allows with your existing fiber optic network. Without deploying additional optical fiber, WDM network mux multiplexes multiple optical signal on a single optical fiber by using different wavelengths, which greatly relieves [ Continue reading…]

Brief introduction of DWDM Technology and DWDM System Components

  Telecommunications makes wide use of optical techniques in which the carrier wave belongs to the classical optical domain. The wave modulation allows transmission of analog or digital signals up to a few gigahertz (GHz) or gigabits per second (Gbps) on a carrier of very high frequency, typically 186 to [ Continue reading…]
