How Telecom Multiplexers Work: SONET, DWDM and ROADM
Introduction In this article we will be discussing optical multiplexers. Optical multiplexers were the successor to lower-bandwidth copper based T1 and T3 multiplexers. I discuss T-Carrier and FDM multiplexers in this previous article: How Telecom Multiplexers Work: From FDM to T1 and T3. What is SONET/SDH? SONET stands for Synchronous Optical Networking. It is also…
