CWDM is a fiber-optic technology that combines multiple optical signals, each at a distinct wavelength, onto a single fiber. The term "coarse" refers to its wider wavelength spacing, typically 20 nanometers, compared to Dense Wavelength Division Multiplexing (DWDM), which has much narrower spacing (0.4–1.6 nm) . CWDM modules are designed to work with this technology, enabling multiple data streams—such as voice, video, and data—to travel simultaneously without interference .
A CWDM optical module functions as part of a multiplexer/demultiplexer system:
A CWDM optical module is a passive or semi-passive device that enables coarse wavelength multiplexing, allowing multiple independent data streams to share a single fiber. Its simplicity, cost efficiency, and ability to expand network capacity make it ideal for short- to medium-distance optical networks, particularly in metro and enterprise environments .
