A ROADM (Reconfigurable Optical Add-Drop Multiplexer) is a type of optical switch used in optical networks. It is used to add, drop, or pass through optical signals in a network. ROADMs are used to increase the flexibility of optical networks, allowing for dynamic reconfiguration of the network. This allows for more efficient use of network resources, as well as the ability to quickly respond to changes in network traffic. ROADMs are used in a variety of network architectures, including WDM (Wavelength Division Multiplexing), DWDM (Dense Wavelength Division Multiplexing), and OTN (Optical Transport Network). They are also used in metro, regional, and long-haul networks. ROADM technology is becoming increasingly important in the telecommunications industry, as it allows for more efficient use of network resources and faster response times. Companies in the ROADM market include Ciena, Infinera, Huawei, Nokia, and ZTE. Show Less Read more
