Product Information
Full details
This 25-meter Loops telephone cable is designed for advanced communication setups requiring more internal cores than standard cables. Its key benefit is providing 12 pairs (24 cores) for complex installations, but a caveat is that 25m lengths may not be supplied on a reel. It's ideal for multiline phone systems and certain CCTV applications, offering structured core color coding for easier identification.

FAQs
What is the main advantage of a 12-pair cable over a standard 2 or 3-pair cable?
A 12-pair cable offers significantly more internal wiring capacity (24 individual cores). This allows for more complex installations, such as connecting multiple phone lines to different extensions, integrating additional communication devices, or running multiple signals over a single cable run.
Can this cable be used for Ethernet (networking)?
This cable is specifically designed as a telephone cable and typically uses different conductor types and impedance matching than required for standard Ethernet networking. While it might be technically possible to adapt it for very basic, short-run data transmission, it is not recommended or certified for reliable Ethernet performance.
What does '24 cores, organized into 12 pairs' mean?
It means there are 24 individual insulated wires (cores) inside the cable. These are bundled together into 12 sets of two wires, known as pairs. Each pair is typically twisted together to help reduce interference.
What is an IDC insertion tool?
An IDC (Insulation-Displacement Connector) insertion tool is a specialized tool used to terminate wires onto connection blocks like those found on telephone faceplates. It pushes the wire into a connector slot, piercing the insulation to make electrical contact without needing to strip the wire first.
Can I use this cable for long-distance communication runs?
The cable has a maximum working voltage of 80V and a current rating of 0.25A per core. While suitable for typical in-building telephone runs, signal degradation over very long distances may occur depending on the specific application and equipment used. Always check the requirements of your communication system.
Why might a 25m cable not be supplied on a reel?
For shorter lengths, especially those that might be shipped directly to a customer for a specific installation, it can be more practical and cost-effective for the manufacturer to simply coil the cable rather than wind it onto a plastic or wooden reel.
Troubleshooting
No signal / Poor connection on one or more lines
Check that all cores are properly terminated at both ends. Ensure the correct pairs are connected to the corresponding ports. Verify that the IDC tool was used correctly if applicable. Inspect cable for damage or sharp bends.
Intermittent connection or static noise
Ensure the cable is not running parallel and too close to high-power electrical cables. Check for loose connections at termination points. Verify that the cable is not damaged along its length.
Difficulty terminating using IDC tool
Ensure you are using the correct type of IDC faceplate/connector designed for this cable's gauge (0.2mm² CSA). Make sure the tool is aligned correctly over the core and connector before actuation.
Pros and Cons
Pros
- High core count (12 pairs) supports complex wiring needs.
- Color-coded pairs simplify installation and troubleshooting.
- Compatible with IDC termination tools.
- Suitable for advanced telephone and CCTV systems.
- Durable white jacket for clear identification.
Cons
- 25m lengths may not be supplied on a reel.
- Higher core count may be overkill for basic installations.
- Copper clad steel conductors may have different conductivity than pure copper.
- Lower current and voltage ratings compared to some industrial network cables.
Setup, Compatibility & Care
Setup:
- Identify Pairs: Use the provided core color coding for pairs 1 through 12 to plan your connections.
- Termination: Connect the desired cores to your communication equipment or faceplates. For faceplates, an IDC insertion tool is recommended for a secure and efficient termination.
- Cable Management: Route the cable carefully, avoiding sharp bends or kinks to maintain signal integrity. Secure the cable using appropriate clips or ties.
Compatibility:
- Telephone Systems: Compatible with standard analog and digital telephone systems, PBXs, and VoIP gateways that utilize RJ11 or similar modular connectors, provided the connection hardware supports 12 pairs.
- CCTV Systems: Can be adapted for certain CCTV systems, particularly those using baluns that require multiple conductors for signal and power. Always verify compatibility with your specific CCTV equipment.
- Faceplates: Designed for use with telephone faceplates that support IDC termination.
Care:
- Cleaning: Wipe the exterior jacket with a dry or slightly damp cloth. Avoid harsh chemicals or solvents.
- Environment: Install in a dry environment. Avoid prolonged exposure to excessive heat, moisture, or direct sunlight, which can degrade the jacket material.
- Strain Relief: Ensure connections are not under excessive physical strain to prevent wire breakage or poor contact.
