1. Optical amplifiers: Used to boost the signal strength of optical signals as they travel long distances in the fiber optic network.
2. Optical filters: Used to separate different wavelengths of light in the DWDM system, allowing for multiple signals to be transmitted simultaneously over the same fiber.
3. Optical multiplexers and demultiplexers: Used to combine and separate multiple optical signals at different wavelengths in the DWDM system.
4. Optical switches: Used to route optical signals to different paths in the network, allowing for flexible and efficient data transmission.
5. Optical transceivers: Used to convert electrical signals into optical signals for transmission over the fiber optic network, and vice versa.
6. Optical add-drop multiplexers (OADMs): Used to add or drop specific wavelengths of light from the DWDM system, allowing for flexible network configurations.
7. Optical dispersion compensators: Used to compensate for the dispersion of optical signals as they travel through the fiber optic network, ensuring signal integrity and quality.

Dense wavelength-division multiplexing (DWDM) is an optical fiber multiplexing technology that is used to increase the bandwidth of existing fiber networks. It combines data signals from different sources over a single pair of optical fiber, while maintaining complete separation of the data streams. This is a laser technology used to increase bandwidth over existing fiber optic backbones. DWDM technology is an extension of optical network, the main advantage of DWDM is that it is independent of protocol and transmission rate, DWDM-based network can transmit data in IP, ATM, SONET, SDH and Ethernet. https://www.glsun.com/article-p108-what-are-the-common-used-optical-devices-in-dwdm-system.html
