These 30 pair telephone cables are commonly used in telecommunications and networking applications to connect telephone systems, exchange lines, and other communication equipment. The cable contains 30 pairs of individual copper conductors. Each pair consists of two wires twisted together. These pairs are color-coded and numbered for identification. The gauge or thickness of the individual conductors within the cable can vary depending on the specific cable’s design and intended use.

Each pair of wires within the cable is twisted together. Twisting helps reduce electromagnetic interference (EMI) and crosstalk between adjacent pairs, which is important for maintaining signal quality in telecommunication applications. Additionally, the outer jacket of the cable is typically made of a durable and protective material, which provides mechanical protection and helps resist environmental factors.

This 30-pair telephone cable is commonly used in telecommunications infrastructure, including telephone exchanges, private branch exchanges (PBX), and wiring within buildings. It provides a means of connecting multiple telephone lines and supporting voice and data communication needs. Telephone cables are typically terminated with connectors that match the type of equipment being connected. Common connectors include RJ-11 and RJ-45 connectors for telephone and data applications.
