Build FTTH networks faster and easier than ever.


We are using one of the worlds most advanced methods for laying ducts for fiber cables in streets and sidewalks. The method builds on a technology called microtrenching, which has been further developed into a highly automated process. Behind this new method is a brand new machine, first in it's category, that instead of digging is sawing through the asphalt or concrete surface layer and down into the underlying bearing layers. At the same time the machine automatically places a large number of ducts on the bottom of the trench. Each of these ducts being dedicated for one of the homes passed. The installation capacity of the machine is between 300-600 meters per day.


The method also includes a professional and industrialized method for refilling and sealing of the area. In order not to damage existing infrastructure, a GEO-radar is used to scan the area. This information is then saved and later used when planning the installation.

The machine

Our machine stands out from the crowd. It only takes two people for its operation and in total only four people to keep everything running for making a complete fiber to the home network. Not only that, at the same time as you trench, the installation is accurately documented in X, Y as well as Z-direction (depth).



Stockholm, Sweden

The broadband exhibition in Stockholm is an exhibition about creating future sustainable communication expansions in Sweden. We got a lot of positive reaction and brought loads of curiosity with our new machine. With us at our stand we had Tim Axelsson and Andreas A (seen in picture).

By using a mix deployment of machines we we can cut the numbers of teams needed to make the same amount of work in a shorter time substantially. Seen above is a case based on a deployment of 1000 000 homes where 40% is micro trenching and 60% traditional excavating.

Cost efficient

Our unique trenching method is up to 2-3 times faster than using traditional excavation. Our microtrenching method builds on an advanced saw, that instead of digging creates a fine cut in the ground by pulverizing the material. The result is a fast, easy to use and cost efficient method that replaces traditional excavation methods.

With our micro trenching solution laying ducts for FTTH networks is as effective as possible. With this method the duct per meter can be minimized and so can the trenching per lot. Seen above is single side trenching which is most effective, if trenching branches(across the street) isn't allowed double side trenching is used.

Diamond trenching

Important to separate is trenching with carbide teeth and trenching with diamond blades. Our machine is exclusively made for diamond trenching and have an average rotating speed of 900 rpm compared to machines with carbide teeth that rotates with only around 200 rpm. The diamond blade that has such high rotate speed cuts right trough and pulverize any obstacles. The advantages of that is that you get a monotonous cut with straight standing walls and a very even cut. This makes the refilling process easy and the sealing cost effective due to always having the same narrow width of the cut. Seen in picture is how a cut can look like in the reality, we can easily fit 17 pcs 7/3,5 mm ducts and 2 pcs 14/10 mm ducts. (This combination of ducts for FTTH have proven to be very effective and cost-efficient in Sweden)

No matter the type of the road, the process is the same. Our method pulverises the material instead of digging. The advantages are many but most of all it creates a fine narrow cut, that makes little to none damage to the road.


In comparison with normal excavation methods our method is significantly more cost efficient. The machine saws up to 380 mm (15 inches) deep and only 28 mm (1,1 inches) wide. By this, the traffic can be allowed to run smoothly and without interruption over open trenches. Our method is not only faster and less costly but it also retains the road in full  functional condition while the installation process is still going on. The cost to restore the road is low especially considering how little time it takes to do the job.
