about us

Our team of motivated professionals is prepared to work toward achieving your goals in building telecommunication systems, information systems, safety systems and other construction-related activities.


S com started as a licensed trade company in February 1992. It drew on the experience of the founder of the company, Svatopluk Fröhlich, who at the time had already been building telecommunication projects, designing, and installing interior communications for fifteen years. In 1993, the company’s team grew to twenty experienced workers, whose primary activities included building computer networks and installing phone exchanges. In the following period, the company designed local telephone networks for Český Telecom, installed Systimax and RiT structured cabling, and in 1998 became S com s.r.o. A breakthrough in the activities of the company came with their specialization in optical networks in 2000, and with the expansion of their activities through the laying of cable networks and the introduction of optical microcable technology and microtubing. Their specialization was topped off by engineering and designing in capital construction.

In 2008, the company increased their capital stock to CZK 2 million for the second time, and Jaroslav Vasilev became a partner of Svatopluk Fröhlich. Since 2015, the building of optical networks has been extended to include railway construction and other transport-related construction.
