What Is CWDM Technology and How It Works
CWDM (Coarse Wavelength Division Multiplexing) is a powerful fiber optic solution for high-speed, long-distance networking. It''s one of several fiber optic cable choices, and it can fill many roles.
CWDM combines multiple laser beam signals of different wavelengths for fiber optic transmission on a single fiber. CWDM has fewer channels than DWDM and both these technologies are used to increase the bandwidth of fiber...

CWDM (Coarse Wavelength Division Multiplexing) is a powerful fiber optic solution for high-speed, long-distance networking. It''s one of several fiber optic cable choices, and it can fill many roles.
Coarse wavelength-division multiplexing (CWDM), in contrast to DWDM, uses increased channel spacing to allow less sophisticated and thus cheaper transceiver designs.
CWDM uses a multiplexer to divide the light wavelengths into different channels, each carrying a separate data stream. The channels are
Coarse wave division multiplexing (CWDM) allows several signals to be transmitted simultaneously at various wavelengths via a single optical cable.
CWDM uses a multiplexer to divide the light wavelengths into different channels, each carrying a separate data stream. The channels are combined and transmitted over a single fibre

A WDM system uses a multiplexer at the transmitter to join the several signals together and a demultiplexer at the receiver to split them apart. With the right type of fiber, it is possible to have a device that does both simultaneously and can function as an optical add-drop multiplexer. The optical filtering devices used have conventionally been etalons (stable solid-state single-frequency Fabry–Pérot interferometers in the form of
Unlike CWDM, the wavelengths in DWDM are more tightly packed, and connections can be amplified. This means that data can be transmitted over much longer distances.
The Cisco CWDM SFP solution helps enable enterprises and service providers to increase the bandwidth of an existing Gigabit Ethernet optical infrastructure without adding new fiber strands.
CommScope''s CWDM Modules are part of our value-added module (VAM) system that provides flexibility, scalability and functionality to an optical transport system.
Corning coarse wavelength division multiplexing (CWDM) solutions utilize advanced thin-film-filter technology. CWDM solutions are available in industry-standard 20 nm spacing with options for a
