Looking for the best Wavelength providers in San Francisco in California, United States? Here's your ultimate guide to making an informed choice.
What is Wavelength?
Wavelength services, often referred to as 'Wave Services,' are a high-capacity, low-latency WAN connectivity solution. They use dense wavelength division multiplexing (DWDM) technology to deliver multiple, private circuits over a single pair of fiber, making them ideal for transmitting large amounts of time-sensitive data.
Wavelength providers are highly dependent on the availability of fiber infrastructure in specific locations. This means that the presence and pricing of Wave services can vary significantly based on the geographic area and the existing network setup.
