Searching for the top Wavelength providers in Columbia, South Carolina? 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, point-to-point WAN connectivity solution. Utilizing dense wavelength division multiplexing (DWDM) technology, these services can 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 specific network infrastructure. The need for robust, modern fiber optic networks means that these services are typically only available in areas where such infrastructure is present, making location a critical factor in service availability and pricing.
