Reliable data on land
Over the past 30 years, we have designed and installed telecommunications networks in countless different locations. Our installations can be found all over the country.
We are responsible for the operation of domestic operators' backbone networks and access networks. This means that we keep countless Finns connected with reliable, uninterrupted data networks all over the country.
We design, build and maintain the energy company Rauma Energia's fiber optic network, from production to the end user.
We have built FTTH networks (Fiber to the home) in Northern and Eastern Finland.
Comprehensive data solutions in the air
Airborne data traffic is increasing all the time. We design, install and measure WLAN networks as complete solutions. One of our successful large-scale projects is a wireless network built for an international operator in the Port of Rauma.
For our clients, it is essential that the networks operate comprehensively and reliably throughout their areas of operation. At the Port of Rauma the vast size of the area, which is over a square kilometer, shows the challenge of the installation and measurement work. We successfully designed and implemented the network from start to finish.
Decades of experience and the most extensive fibre optic equipment on the Finnish West Coast ensure first-class results every time. Focus on your business — we make your data move.

From large-scale comprehensive solutions to individual installations, services and maintenance, we serve in information networks with experience built on 30 years and thousands of projects. We assess your needs and always offer the best and most efficient solutions.
Comprehensive solutions
We build everything you need for a functioning telecommunications network – from offices to data centers, regardless of size. Our complete solutions always include everything: design, implementation and deployment, from start to finish.

We install all the necessary equipment, accessories and materials for both active and passive network systems. If you need a tailored system solution, we're here to help. Even for large-scale projects, our extensive partner network enables us to find the right solution for your specific needs.
Maintenance
We proactively keep your data and your entire IT management up and running. We measure, analyze and, if necessary, repair your telecommunications networks. We also conduct survey visits to help optimize your company's telecommunications to meet the latest requirements.
Material supply
We supply all the materials needed for high-quality data network solutions – e.g. panels, fibre optic pigtails and other fibre optic accessories – from data centres to wireless networks. Whenever possible, we pre-assemble products before delivery. We also ensure that all packaging materials are properly recycled.
