Technology blogger Ike Elliott has a terrific series underway over at his blog this week looking at the differences between cable and telco-fiber infrastructures. He is “looking at why cable companies are kicking the tires on fiber-based passive optical networks, even though they have a heavy investment in hybrid fiber coax (HFC) networks.” The series is a good primer on these issues.

- “Fiber vs. Coax“
- “DOCSIS 3.0 Upstream Still Skinny“
- “When Will Cable Bite The Bullet and Upgrade to Fiber?”
And here’s a handy table that Ike put together comparing the capabilities of fiber vs. coax:
