In today’s rapidly evolving optical communication networks, optical add-drop multiplexing devices play a crucial role in optimizing network architecture and enhancing transmission efficiency. Examples of these devices include ROADMs (Reconfigurable Optical Add-Drop Multiplexers) and FOADMs (Fixed Optical Add-Drop Multiplexers). While both aim to achieve optical signal add-drop multiplexing, they differ significantly in several aspects. A… Continue reading The difference between ROADM and FOADM
