The Podcast Goes Dark! (Dark Fiber, That is)

We haven't been getting enough fiber here at TeleGeography Explains the Internet, but we're about to change that.

Nutritional jokes aside, this week, we welcome Todd Chapman, a veteran in fiber development, to the hot seat. Todd walks us through the ins and outs of Layer 0 of the physical infrastructure underlying data transmission. Some classic explaining of the internet. 

In this episode, you'll get a walkthrough of the process that takes a fiber project from manufacturing to lit service—get ready to learn a thing or two about different types of fiber and their uses. We also get some good explanations of the dark fiber market and an overview of when enterprises might be interested in leasing dark fiber instead of lit service.

Here's a glimpse at what we discussed. Scroll to the bottom to listen to the whole discussion in its fiber-rich glory.

2024: A Telecom Year in Review

Happy holidays, TeleGeography Explains the Internet listeners.

We hope you're savoring the brief week between Christmas and New Year's when the world takes a moment to pause and reflect. School is out, schedules are topsy-turvy, and cookies are acceptable for breakfast. Perhaps like some of us, you've lost track of movies watched and presents wrapped.

If you're looking to take a break between the winter gatherings, grab some headphones. We've got you covered for an hour or so.

Who Orchestrates the Orchestrators?

Last week on the pod, we shared what network managers need to know about AI and machine learning. This week, we're back on the AI beat, specifically looking at how it can support corporate network automation.

Per usual, we had a little help. Our guest today is Jamie Pugh, CTO at Globalgig.

Jamie joined the show not only to ponder all things automation but also to discuss enterprise network orchestration in the era of an increasingly complex WAN.

Six Insights from Our 2024 Business Broadband Analysis

The role of business broadband in WAN architecture is evolving. It’s no longer just a backup option—many enterprises now rely on it for core connectivity.

Thanks to the rise of cloud services and SaaS applications, broadband’s flexibility and cost-effectiveness make it a strong contender against legacy services like MPLS and DIA.

We’ve collected data from 170+ countries for our Business Broadband Pricing Database, covering nearly 7,000 broadband plans that range from 1 Mbps to 10 Gbps.
