Searching for top-notch Wavelength providers in Seattle? Here's your ultimate guide to making an informed choice.
What is Wavelength?
Wavelength services, often referred to as "Wave Services," are a type of high-capacity Wide Area Network (WAN) connectivity. Utilizing dense wavelength division multiplexing (DWDM) technology, they enable multiple, private, high-capacity circuits to be delivered over a single pair of fiber, offering speeds up to 100 Gbps.
Wavelength providers are inherently location-based, relying on the availability of specific network infrastructure in a given area. This dependency means that the presence of fiber at and between each address is crucial for delivering these high-capacity services. As a result, the availability of Wavelength services can vary significantly by region.
Overview of Providers in Seattle Offering Wavelength
There are many Wavelength providers to choose from in Seattle, with an estimated 51 available based on Lightyear’s network intelligence—the industry’s most comprehensive dataset.
Actual provider availability also depends on fiber infrastructure near a specific address—so while many exist citywide, not all are quote-ready for every location. Comparing options can quickly become overwhelming.
