Case Study: Technical Due Diligence on an FTTH Network

Cartesian provided technical advice to support the acquisition of a regional fiber network. Our report provided confidence to the investors that the network could be successfully integrated and subsequently expanded.

Client Case Study

Our client’s situation

A Network Operator planned to acquire a regional FTTH network. The Operator had an experienced in-house engineering team which had already built out a large FTTH network; however, it wanted an independent technical assessment of the target network as a second opinion that could be shared with its investors.

How we approached the issue

In this technical due diligence, Cartesian set out to understand the quality of the network from a design and implementation perspective. This was important to our client from a present-day perspective, and also in terms of future growth. Hence, we assessed whether there were any risks in the design to scaling and evolving the network over time.

As our client had an existing network, our assessment also considered the ease of integration and feature parity between the two estates.

What we did to help

Cartesian delivered this project with an expert team from its Strategy Consulting division, with experience in fiber broadband, network construction, passive infrastructure, network architecture, and operations.

Using materials from the data room, our team analyzed specifications for the network construction, network design, and aggregation sites. We then reviewed the network inventory to understand the make, model and version of equipment in the network, to determine feature availability, and any issues regarding future upgrades.

The desktop review was supported by site visits to aggregation nodes and street works, for example inspecting the installation practice for underground fiber cables and how these were jointed/spliced in street cabinets.

The end result

Cartesian synthesized its findings in a due diligence report that presented a technical overview of the target network, highlighting any potential issues. Our report gave the client an independent view of the quality of the network, including the civil infrastructure, the passive fiber layer and the network electronics. This provided confidence to the investors that the network could be successfully integrated and subsequently expanded.
