Product Features
Technical Overview
This telephone cable utilizes standard RJ-11 connectors on both ends, with one end specifically configured as a phone connector for direct device attachment. The 4-wire construction provides complete connectivity for multi-line telephone systems or devices requiring additional conductors beyond basic 2-wire configurations.
With a data transfer rate of 1 Mbit/s, the cable supports both traditional analog voice signals and basic digital data transmission where compatible with connected equipment. The stranded copper conductors within the cable offer superior flexibility compared to solid-core alternatives, making installation easier in tight spaces or when routing around obstacles.
This section brings together practical product details such as Cable Type, Cable Length, Connector Type on First End, Country of Origin, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.

FAQ
What devices can I connect with this RJ-11 cable?
This cable connects standard telephones, fax machines, modems, and other communication devices with RJ-11 ports. It supports both traditional analog voice equipment and devices requiring basic data transmission up to 1 Mbit/s where compatible with the connected equipment's capabilities.
How does the 4-wire configuration differ from standard 2-wire phone cables?
The 4-wire configuration provides two additional conductors beyond basic 2-wire cables, enabling support for multi-line telephone systems, advanced features like speakerphone functionality, or devices requiring additional signaling paths. This makes the cable compatible with a wider range of telephone equipment while maintaining backward compatibility with standard 2-wire connections.
What advantages does stranded construction offer for telephone cables?
Stranded construction uses multiple thin wires twisted together rather than a single solid conductor, providing significantly greater flexibility and resistance to breakage from bending or movement. This makes installation easier in tight spaces and ensures long-term reliability even when cables are frequently repositioned or routed around obstacles.
Can this cable be used for VoIP phone systems?
This cable provides the physical RJ-11 connection between devices, but VoIP functionality depends on the connected equipment. Traditional analog telephones connected to VoIP adapters can use this cable, while IP phones typically require Ethernet connections. The cable supports the physical layer connection where RJ-11 interfaces are present in the communication path.
What is the maximum recommended distance for reliable performance?
The 25-foot length is well within standard performance limits for RJ-11 telephone connections, which typically maintain signal quality up to several hundred feet for voice applications. At 25 feet, this cable provides reliable connectivity without signal degradation for both voice and the supported 1 Mbit/s data transmission where compatible with connected devices.
Does this cable include connectors on both ends?
Yes, the cable features RJ-11 connectors on both ends, with one end specifically configured as a phone connector for direct attachment to telephone equipment. The cross-pin configuration ensures proper conductor alignment at both connection points for consistent signal transmission across all four wires.
