Specifications of Optical Cables for Power Applications

Power optical cables combine fiber optic strands for data transmission with copper conductors for power delivery, supporting long-distance, high-performance applications like PTZ cameras, DAS, and PON systems.Overview

Power optical cables, also known as composite fiber cables, integrate fiber optic cores for network connectivity and copper conductors for power delivery. These cables are designed for applications where both remote power and data transmission are required, often extending beyond 100 meters while maintaining signal integrity and power efficiency . They are suitable for indoor, outdoor, plenum, and high-noise environments.

Key Specifications

• Fiber Type: Single-mode (OS2) or multimode (OM3/OM4/OM5), with bend-insensitive fibers for improved durability .
• Core Construction: Glass core with 125 µm cladding, 250 µm acrylate coating, and 900 µm buffer in a 2 mm subunit .
• Power Conductors: Stranded copper pairs capable of delivering PoE or limited SELV power, with derating calculations per TIA 568 and NEC standards .
• Jacket and Ratings: Plenum-rated (OFCP), UL CMP-OF/CL3P-OF, RoHS 3 compliant, suitable for lashed aerial, duct, or outdoor installations .
