Advanced Construction for Superior Performance
Each Camcom outdoor telephone cable is manufactured using solid annealed bare copper conductors, arranged in precision-twisted pairs to minimize crosstalk and maintain consistent transmission quality across long distances. Insulation options include solid polyethylene (PE) or skin-foam-skin structures, selected based on application requirements.
For underground or ducted routes, jelly-filled or water-blocking gel materials protect the cable core from moisture, preserving long-term insulation performance.
The outer sheath—crafted from UV-resistant black polyethylene (PE)—provides exceptional resistance to sunlight, abrasion, and chemical exposure. For environments with electromagnetic interference, shielded variants with aluminum-polyester tape and a drain wire ensure stable, noise-free operation.

Environmental Protection & Mechanical Strength
• UV-Resistant PE Sheath: Maintains long-term performance under direct sunlight and prevents surface cracking.
• Water-Blocking Design: Jelly or thixotropic gel cores safeguard against moisture ingress in underground installations.
• Robust Mechanical Protection: Durable PE sheathing resists crushing, abrasion, and bending stress during installation and operation.
• Wide Thermal Range: Engineered for continuous operation from –30°C to +70°C, with storage temperatures up to +85°C.
• Rodent Deterrence: Tough PE materials help prevent rodent damage; conduits are recommended in high-risk zones.

Camcom Outdoor Telephone Cable Portfolio
One of Camcom’s flagship models is the A-02YSF(L)2Y—a jelly-filled, PE-sheathed, multi-pair outdoor telephone cable designed for long-term reliability. Available from 2 to 1000 pairs, it can be customized for telecom and control requirements.
Key Features:
• Conductor: Solid bare copper (0.4 mm / 0.6 mm).
• Insulation: Color-coded solid PE based on TIA-598 or custom schemes.
• Pair Formation: Precisely twisted pairs to reduce crosstalk.
• Filling: Fully jelly-filled core (A-02YSF(L)2Y) or dry-core options.
• Sheath: Black UV-resistant PE (LDPE/HDPE).
• Optional Shielding: Aluminum-polyester tape with tinned copper drain wire for EMI resistance.
Every cable undergoes rigorous testing—capacitance, DC resistance, insulation verification, and high-voltage testing—to guarantee reliable performance across all environments. Camcom also offers customized striping, labeling, and drum marking for project-specific needs.

Frequently Asked Questions
What type of cable is used for landline phones?
Landline systems use twisted-pair copper cables. Indoor networks typically use 2- or 4-wire variants (e.g., Cat3 or CW1308), while outdoor routes rely on jelly-filled, PE-sheathed multi-pair telephone cables for ducts, burial, or aerial installation.
Are telephone cables still used?
Yes. Even with the shift to IP-based communication, copper telephone cables remain vital for POTS/FXS lines, alarms, intercoms, legacy loops, and low-speed industrial control circuits.
Which cable is suitable for outdoor use?
Outdoor-grade, UV-resistant, PE-sheathed telephone cables with jelly-filled or water-blocked designs are ideal for ducts and direct burial. Shielded versions are recommended in areas with electromagnetic interference.
What is a telecommunication cable?
A telecommunication cable carries voice or data using twisted-pair copper, coaxial, or fiber. Outdoor telephone cables represent the copper category designed for carrier-grade voice and signaling.
What is a telephone cable called?
Common terms include telephone pair cable, multi-pair copper cable, jelly-filled telephone cable, or designations such as A-02YSF(L)2Y for PE-sheathed outdoor types.
What is Telco cable?
“Telco cable” often refers to a 25-pair copper cable terminated with an RJ21 (Amphenol) connector, or more broadly, any carrier-grade multi-pair telephone cable used for telecom distribution.
