Coaxial cables with an impedance of 75 ohms are used in DVB-T2 terrestrial TV systems, satellite TV systems and video surveillance systems. Inside buildings, cables with PVC or halogen-free (LSZH) sheaths are used, with flammability class appropriate for the application. For outdoor use, cables with polyethylene (PE) sheath, resistant to UV radiation, are recommended.
Cables class RG-59, RG-6, RG-11 and TRISET-113 are available, with screening classes from B to A++ and fire resistance classes from Fca to B2ca.
Coaxial cables with an impedance of 50 ohms are used in WLAN systems, as well as in solutions improving the reception of GSM and LTE signals.
Twisted-pair is a signal cable type used to transmit information over telecommunications links and computer networks. Currently it is most often used in analog telephony and in Ethernet networks. It is made up of one or more pairs of conductors twisted together. The twist is intended to eliminate the influence of electromagnetic interference and mutual interference, so called crosstalk.
Indoor and outdoor twisted-pair cables, in categories ranging from cat. 5e to cat. 7 in shielded and unshielded versions and fire resistance classes from Fca to B2ca are available.
Fiber optic cables can be divided into indoor, outdoor and universal cables, depending on the place and method of installation. Furthermore, within these groups, we can distinguish cables for special applications, such as self-supporting fiber optic cables and underground fiber optic cables. We offer fiber optic cables with single mode and multimode fibers.
