More information
Product Introduction
Also known as multipair cables, these cables consist of numerous pairs of twisted copper wires bundled within a protective sheath. Designed for high-density voice communications, they are widely used in telephone networks, commercial buildings, and telecommunications infrastructure to support multiple channels simultaneously, ensuring reliable transmission with minimal interference.
Features
Large-pair telephone cables feature a high-density arrangement of individually insulated copper pairs, typically color-coded for easy identification. Their twisted-pair design reduces electromagnetic interference (EMI) and crosstalk, while their thick outer jacket provides resistance to moisture, abrasion, and UV rays. Ideal for trunk installations, these cables ensure a stable signal over long distances and are compatible with traditional telephony, DSL, or VoIP applications.
Applications
Large-pair telephone cables serve as backbone lines in telecommunications networks, connecting telephone exchanges (COs) to distribution points or linking multi-tenant buildings. Their high capacity supports fixed-line telephone systems, DSL broadband, and traditional analog services, while their durability ensures reliable performance in harsh environments, such as underground conduits or overhead pole installations.
