![]() ![]() ![]() Some are DWDM systems with integrated SONET units that provide grooming, add/drop and protection of the wavelength. A new generation of apparatus is also being presented that provides options that come with both SONET and DWDM. When compared with traditional SONET, the next generation of DWDM (Dense Wavelength Division Multiplexing) is seen as a simple architecture, scalability, high capacity add/drop, multiple ring terminations, multi-services, and multiple fabrics.Īt the same time, DWDM Equipment is increasingly showing its viability in the current metro networks with tremendous available bandwidth over the existing fiber plant, along with a variety of service interfaces and superior optical transmission capabilities. The next generation of SONET (Synchronous Optical Network) or SDH (Synchronous Digital Hierarchy) equipment continues to be well accepted by service providers and is being usefully deployed into networks right now to carry continually increasing network traffic. ![]()
