Wavelength Services Powered by DWDM Networks

Wavelength services give you a dedicated optical channel (a “lambda”) between two locations over a provider’s fiber network. You’re essentially renting high-capacity, point-to-point bandwidth without owning or managing the underlying fiber.

Dense Wavelength Division Multiplexing (DWDM) is a technology used in fiber-optic communications that enables the transmission of multiple data signals simultaneously over the same optical fiber by using different wavelengths (or colors) of laser light. This technique significantly increases the capacity of the fiber by allowing multiple channels to be transmitted concurrently, each channel carrying a separate data stream.

DWDM can handle hundreds of separate wavelengths, each carrying data at high speeds, effectively turning a single fiber into a multi-lane highway for data transmission. This technology is essential for the backbone of modern high-capacity networks, as it maximizes the amount of data that can be sent over long distances with minimal signal degradation.

Businesses that typically need DWDM technology are those with high data transmission demands, requiring large bandwidth capacities and long-distance communication.

DWDM (Dense Wavelength Division Multiplexing) packs many tightly spaced wavelengths onto a single fiber, ideal for very high capacity and long distances. CWDM (Coarse WDM) uses fewer, more widely spaced wavelengths, making it cheaper but with lower capacity and shorter reach.

DWDM massively increases capacity over existing fiber, lets you scale bandwidth without new construction, supports long distances, and provides flexible, high-performance connectivity for data centers, carriers, and large enterprises.

No. Dark fiber is unused fiber infrastructure, while DWDM is the technology used to “light” fiber with multiple wavelengths. You can run DWDM over dark fiber that you own or lease to turn it into high-capacity transport.

DWDM is designed primarily for single-mode fiber, especially for long-distance and high-capacity links. While WDM concepts can exist on multimode, real-world DWDM networks almost always use single-mode.
