Quick answer
Communication cables carry information — data, audio and video signals — rather than mains power. Because they handle high-frequency signals, they are built for low interference and signal integrity, with careful shielding and conductor geometry.
Common types and what they do:
- LAN (Ethernet) cables — computer networking and internet connectivity;
- CATV cables — cable-television signal distribution;
- CCTV cables — security and surveillance camera feeds;
- speaker cables — audio between amplifiers and loudspeakers; and
- Uninyvin cables — light-duty wiring and control/communication uses.
Several of these (CATV and CCTV) are coaxial in construction, while LAN cables use twisted pairs; high-bandwidth backbones may use optical fibre. Explore APAR's full communication cables (Tarang Shakti) range to match a cable to your signal type.
