Data transmission calls for increasingly higher speeds and capacity. Its practically unlimited bandwidths and low attenuation makes optical fibre technology the best solution to these challenges. Since increasingly more significant economic values are tied up in data networks, connection reliability and accessibility have become important criteria when measuring cable quality. In addition to speed and capacity, cables need to have outstanding mechanical properties such as strength, easy installation and durability. This ensures dependable, faultless function and minimises the cost of network maintenance, repair and service. Helkama optical fibre cables are designed to last at least 30 years. Our quality system has been found to comply with the ISO 9001 standard. Helkama an experienced Finnish producer Helkama has been making cables for over thirty years, exporting products to all corners of the globe. In addition to optical fibre cables, Helkama makes telecom, shipboard and control cables. The company has production facilities in Kaarina and Hanko in Finland. The roots of Helkama companies go back almost a century. Over the years Helkama companies have successfully managed to keep abreast of the times, making each rank among the leading companies of its kind. For example, Helkama is Finland s leading supplier of optical fibre cables for data networks. Helkama has adequate resources to rapidly introduce the latest technology and to constantly develop new products. Nevertheless, Helkama has remained small enough to allow it to take customers individual needs into account. Customer satisfaction the principal goal Helkama is committed to customer satisfaction and lasting customer relations, with particular emphasis on service quality and punctual deliveries.
