Cable laying including cables with optical fibers

The AŽD Praha company is at present capable of ensuring the transmission of information not only via classic metal cables but mainly by constructing local and trunk cables with optical fibers that ensure big volumes of transmitted information and that have high quality transmission rates even in condition of strong industrial disturbances. The company carries out the design and the construction of these cable networks via pulling the cable into a beforehand prepared underground protector or by hanging the cables e.g. on posts of the traction power supply. It is equipped with cutting-edge technology for pulling, connecting and measuring fiber-optic cables and so it ensures the high quality of the carried out jobs. Modern PCM transmission systems with time separations of channels are placed on fiber-optic and metallic cables. AŽD Praha carries out the design and assembly and ensures the supply of PCM systems from world renowned producers including network monitoring systems.

Blowing technique

The technique of blowing optical fibers into HDPE tubes is based on experience of AŽD Praha and the experience of the companies Plumett, Vetter and Wolf, the producers of optical fiber blowing systems. For blowing the fiber-optic cable into a HDPE tube we use equipment from the Plumett company, i.e. the Super Jet blowing system, Figaro" basket for un-coiling the cable and an air cooled compressor from the company Zeppelin. After blowing in the cable we mount the optical connectors, check the joints and ends of the optical cables on the optical cable distributor panel.

Production of cables

A significant part of the AZD Prague s.r.o. production is the production of cables for export. Mainly for the company Whirlpool Slovakia where based on the screening of all European suppliers of the Whirlpool company our company was chosen to have the best quality products. We have been able to fulfill the strict requirements every year.
