Built for Excellence
Camcom indoor telephone cables feature solid bare copper conductors arranged in precision-twisted pairs. Why twisted pairs? They reduce crosstalk and maintain consistent signal clarity, giving you clear and reliable communication.
The cables are insulated with high-density polyethylene (PE) for low dielectric loss and long-term electrical integrity.
For environments with high electrical noise, we offer J-Y(St)Y shielded variants. These include:
• Collective aluminum-polyester foil screening
• Tinned copper drain wire for EMI protection
This makes them perfect for installations near power circuits, control equipment, or other sources of interference. The outer sheath is made from flame-retardant grey PVC, meeting EN 60332-1 fire safety standards, while providing durability for everyday use.

Electrical & Performance Features
Camcom indoor telephone cables are designed to deliver clear and reliable voice and signal transmission over short- to medium-distance runs. Key performance features include:
• Controlled Capacitance: ~100 nF/km for J-Y(St)Y types
• Low Crosstalk: Precisely twisted pairs minimize interference
• High Insulation Resistance: Prevents leakage, ensuring line clarity
• Dielectric Strength: Batch-tested to meet international standards
In other words, our cables make sure analog voice quality, signaling, and control communication stay crystal clear.

Frequently Asked Questions
What kind of cable is used in telephones?
Indoor telephone systems typically use twisted-pair copper cables, such as J-Y(St)Y, CW1308, or Cat5e/Cat6 for VoIP and structured wiring.
What is a home phone cable called?
It’s often referred to as a telephone cable, station wire, or by standard codes like CW1308 or J-Y(St)Y. Short patch leads usually use RJ11 connectors.
What’s the difference between RJ11 and RJ12?
• RJ11: 6-position plug, 2–4 conductors (typical residential phone line)
• RJ12: 6-position plug, 6 conductors (used in PBX or multi-line systems)
What’s the best cable for telephone wiring?
For modern installations, Cat5e or Cat6 solid copper cables are recommended for VoIP or analog voice. For traditional analog systems, low-capacitance twisted-pair cables like J-Y(St)Y or CW1308 are ideal. Avoid CCA (copper-clad aluminum) cables for better reliability.
