Zooming in on the CapEx

Trenching is extremely costlySo reduce this as much as possible

Central Office Buried drop point Facade drop point Aerial drop point

And reduce the total deployment length

Central Office Fiber cable Buried drop point Facade drop point Aerial drop point

By constructing a Steiner Tree

NP-hard heuristic techniques

Interesting research topicsClustering & cherry pickingRing structures for resilience

Finally there are also different fiber architectures for the access network

The other parts of the physical deployment have a much smaller impact

Using an alternative to trenching (here aerial) can save considerable

So – We’ve shown an approach forcost breakdown and balanced (zooming) estimation

Up & Running

1. Deployment (70%)

mainly trenching (80%) optimized installation tree cherry picking alternative installation types


Up & Running

Deployment


2. Service Provisioning (25%)

mainly equipment ONU (65%)

advantage of pre-installation reduced trenching early customer binding


Up & Running

Deployment


3. Keep up & running (10%)

mainly maintenance (60%)

In the future we plan to …

Proceed on this approach

Investigate trade-off between CapEx & OpEx Model the cost-structure in more detail Expand this approach to other technologies

(e.g. wireless)
