German government needs options for rapid FTTP deployment

Vodafone calls for German government help with ultrafast broadband rollout | News | DW | 05.05.2019: However, in an interview with Welt am Sonntag newspaper, Vodafone's German chief, Hannes Ametsreiter, said that connecting from the network to individual homes, the so-called last mile, was "extraordinarily challenging."

"It is enormously expensive to rip the road on your own," Ametsreiter said, suggesting that Germany looks at how broadband is rolled out in Spain and Portugal, where the state invests in the infrastructure, laying empty pipes, just as it builds highways.

This is called "dig once" in America. It's a perfectly sensible policy. But it can't meet the urgent need to rapidly replace obsolete copper cable built for the period of analog voice telephone service with fiber to the premise. It will have to go on utility poles where buried conduit does not exist.

Then when future road restoration or other trenching projects are undertaken and conduit installed, the aerial fiber can then be retired. Additionally, there are lower cost methods to deploy aerial fiber near energy lines such as lightweight All-dielectric self-supporting (ADSS) cable that can speed aerial deployment.

Another option is microtrenching provided the road surface is sufficiently thick with a stable base. But it must be ensured the microtrench slot is deep enough lest the conduit be forced out of the microtrench as Google Fiber recently learned to its dismay in Louisville, Kentucky.
