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.
