Application

Ideal for smart community construction, intelligent power grids, and integrated broadband access. Perfect for projects where power and communication need to reach the user terminal simultaneously.

Characteristics

Integrated Design: Combines power supply and optical communication in one cable.
Space Saving: Reduces the need for separate cable runs and pipe occupancy.
Cost Efficiency: Lowers construction and material costs significantly.

Certifications

-CE, RoHS, compliant with ITU-T G.652 standards.

Specifications

OPLC Fiber Optic Cable Constructions

Component	Material/Properties	Details
Optical Fiber Unit	High-purity Silica Glass in PBT Tube	Single-mode or Multi-mode fibers (typically 2 to 24 cores). Housed in a jelly-filled PBT loose tube or a stainless steel tube to protect against heat and stress.
Power Conductor	Bare Copper or Aluminum	Stranded annealed copper (Class 2 or Class 5) or aluminum wires. Used for transmitting low-voltage electrical power.
Conductor Insulation	XLPE (Cross-linked PE) or PVC	Provides high-grade electrical insulation. XLPE is highly recommended for its superior heat resistance (up to 90°C).
Cable Core Filling	Non-hygroscopic PP Yarn / Fillers	Used to fill the interstices between the power conductors and the optical fiber unit, ensuring the cable remains perfectly round.
Wrapping Tape	Non-woven Tape / Flame-retardant Tape	Binds the core together. Water-blocking tape can be used if waterproofing is required.
Armor (Optional)	Steel Tape (STA) or Steel Wire (SWA)	If mechanical protection is needed (e.g., for direct burial), corrugated steel tape or galvanized steel wire is applied.
Outer Jacket	PVC, PE, or LSZH	Outer sheath material. LSZH (Low Smoke Zero Halogen) is highly recommended for indoor/building applications for fire safety.

OPLC Structural & Performance Highlights:

Dual Functionality: Integrates optical fibers for communication and copper/aluminum cores for power transmission, saving installation space and deployment costs.
Power Core Insulation: XLPE (Cross-linked Polyethylene) allowing a maximum continuous operating temperature of 90°C.
Optical Unit Protection: Fibers are typically housed in a protective stainless steel tube or high-modulus PBT loose tube placed in the interstices of the power cores.
Armor & Sheath: Features Steel Tape Armor (STA) for mechanical protection and a weather-resistant PVC or PE outer jacket.
Optical Performance: Attenuation ≤ 0.36 dB/km @1310nm | ≤ 0.22 dB/km @1550nm (ITU-T G.652D standard).
