Have questions? We’ve got answers.
What’s the difference between a Wavelengths services and Ethernet services?
Wavelengths services provide dedicated, point-to-point optical transport over DWDM for ultra-high-speed, ultra-low-latency use cases. Ethernet offers more flexibility and cost-efficiency for multi-site networking.
What’s the maximum bandwidth available with Wavelengths connections?
Wavelengths connections can scale up to 400Gbps depending on your needs and network design.
Are Wavelengths secure?
Yes. Each Wavelengths is physically separated on the fiber and can be protected with diverse routing.
Can I use Wavelengths to connect data centers or cloud sites?
Absolutely. This is one of the most common and ideal applications for Wavelengths.
How is Wavelengths different from Dark Fiber?
With Wavelengths, Fidium provides the equipment and manages the optical layer, delivering dedicated, high-speed connections without the need for you to manage the fiber. Dark Fiber, on the other hand, gives you raw, unlit fiber strands—ideal if you have in-house expertise to manage and light the network yourself for maximum control.
Can I combine Wavelengths with other Fidium solutions like Dark Fiber or Data Center Connectivity?
Yes. Wavelengths can be part of a hybrid network strategy that includes Dark Fiber for maximum control or links to Fidium data centers for colocation and cross-connect options.
What makes Wavelengths different from other transport services?
Wavelengths offer dedicated, ultra-high-capacity optical paths using DWDM, ideal for deterministic routing between critical endpoints.
How fast can Wavelengths go?
Fidium Wavelengths support 10Gbps, 100Gbps, and 400Gbps connections.
Where are your Wavelengths available?
We're continually expanding. Availability depends on route feasibility—contact us for a site check.
Are Wavelengths private and secure?
Yes, Wavelengths are inherently private Layer 1 connections, bypassing shared Layer 2/3 infrastructure.
How do Wavelengths relate to my data center strategy?
They’re ideal for connecting data centers, especially for cloud access, replication or AI workloads where consistent throughput is critical.
