Structured cabling systems are universal, standardized cabling systems designed to transmit data, voice, images, as well as all other low current types of applications that are used in buildings (HVAC control, access systems, video surveillance and so on.). A structured cabling system is the basis of the information infrastructure of any modern enterprise.
