Signalkablar

Signalkablar are cables designed to transmit electrical or optical signals between devices, systems, or sensors. They carry low-power signals rather than main power and are optimized to preserve signal integrity by managing impedance, shielding, and routing. The term is common in Turkish technical literature and closely aligns with the global concept of signal cables.

Construction and types: The main families are twisted pair cables, coaxial cables, and fiber optic cables. Twisted pair cables use pairs of conductors twisted together to reduce interference, with shielding options such as unshielded (UTP) or shielded (STP). Coaxial cables consist of a central conductor, dielectric, shielding, and jacket, offering strong shielding for RF and video applications. Fiber optic cables transmit signals as light and provide very high bandwidth with no metal conduction. Each type has specific construction details, including conductor material, insulation, shielding, and outer jacket, along with connectors and impedance requirements.

Standards and connectors: Signalkablar follow international standards for performance and testing, including ITU-T, ISO/IEC, and IEC series. Common connectors include RJ45 for copper data links, BNC or RCA for RF and analog video, SMA for RF, and LC/SC for fiber. Proper installation emphasizes impedance matching, minimizing crosstalk, ensuring shielding integrity, maintaining adequate bend radii, and protecting against EMI and static discharge.

Applications and maintenance: Used in data networks, telecommunications, audio-visual installations, and industrial process control. Maintenance practices include continuity testing, insulation resistance checks, and, for optical cables, OTDR or power-meter-based tests. The choice of signalkabel depends on distance, bandwidth needs, environmental conditions, and interference levels.
