FAQs & disclaimers

What is the difference between dedicated fiber and shared broadband?

Dedicated fiber provides a private, unshared connection, ensuring consistent performance regardless of other users' activity. Shared broadband shares bandwidth among multiple users, leading to potential slowdowns during peak hours.

Why is symmetrical bandwidth important?

Symmetrical bandwidth provides equal upload and download speeds, which is crucial for applications like video conferencing, cloud-based collaboration, and AI model training that require significant data uploads.

What are the key factors to consider when choosing a dedicated fiber provider?

Key factors include the provider's network infrastructure, service level agreements (SLAs), redundancy options, and ability to provide direct cloud interconnects.

How can I measure the success of a dedicated fiber implementation?

Success can be measured by key performance indicators (KPIs) such as availability, mean time to repair (MTTR), symmetry ratio, and burst utilization. Monitoring per-application experience is also important.
