Descriptions:

- Coarse WDM (CWDM): CWDM is defined by WDM systems with fewer than eight active wavelengths per fiber. CWDM is used for short-range communications, so it employs wide-range frequencies with wavelengths that are spread far apart. Standardized channel spacing permits room for wavelength drift as lasers heat up and cool down during operation. CWDM is a compact and cost-effective option when spectral efficiency is not an important requirement.
- Dense WDM (DWDM): DWDM is defined in terms of frequencies. DWDM’s tighter wavelength spacing fits more channels onto a single fiber, but costs more to implement and operate. DWDM is for systems with more than eight active wavelengths per fiber. DWDM dices spectrum finely, fitting 40-plus channels into the C-band frequency range.

- 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.

- A separate light wavelength carries each signal, and the dense in DWDM refers to its ability to accommodate up to 80 different wavelengths. Each wavelength is about 0.8 nanometer wide and shares a single optical fiber.

- Fiber optic cables now commonly form the backbone of carriers' interoffice networks, representing the standard for the telecommunications infrastructure. DWDM enables enormous amounts of data to traverse a single network link by creating multiple virtual fibers, significantly multiplying the capacity of the physical medium.

- As data flows through distinct wavelengths, the streams or channels do not interfere with each other. This approach helps maintain data integrity. As a result, this enables security-related partitioning or separate tenants in the same data center.

Because of its ability to handle so much data, DWDM is popular with telecommunications and cable companies. It is an integral part of their core networks.

- DWDM is also highly suitable for anyone running densely populated data centers, such as hyperscale cloud service providers operating infrastructure as a service or colocation providers with dense multi-tenant spaces.

- DWDM is a predecessor to a similar technology: time-division multiplexing (TDM), which telecommunications operators use to routinely transmit information at 2.4 gigabits per second (Gbps) on a single fiber. Some also deploy equipment that quadruples that rate to 10 Gbps. However, demand for high-bandwidth applications created capacity demands that exceeded traditional TDM limits.
