In the professional audiovisual (Pro-AV) field, signal transmission stability and cabling flexibility remain core engineering priorities. As digital conference systems demand increased bandwidth and power supply, POF (plastic optical fiber) optoelectronic hybrid cables are emerging as the ideal “artery” connecting network controllers (CCUs), power amplifiers, and microphone units.
Core Technology: Precision Design for Opto-Electrical Synergy
This specialized cable employs a unique physical isolation architecture, integrating two 1mm large-core PMMA plastic optical fibers with two high-purity copper cores within a single LSZH (Low Smoke Zero Halogen) jacket.
- Optical Data Transmission: Leveraging POF’s inherent immunity to electromagnetic interference (EMI), it ensures lossless transmission of high-fidelity audio signals in complex electromagnetic environments.
- Copper Power Supply: The integrated copper cores provide stable DC power to end call stations and speaker units, enabling minimalist “one-cable-to-go” wiring.
Why is it the preferred choice for contractors?
- Simplified Splicing: Thanks to its 1.0mm large core diameter, POF eliminates the need for expensive fusion splicers. Traditional splice closures enable rapid cold splicing, significantly reducing on-site installation complexity.
- Physical Reinforcement: Features a dedicated reinforcement core and independent sheath, providing not only tensile strength but also facilitating separate splicing of fiber and copper cores during maintenance without interference.
- Safety and reliability: The LSZH jacket meets stringent flame-retardant standards, ensuring safety in public spaces like theaters and command centers.
Application Scenarios
Using dedicated network connectors, this hybrid cable seamlessly covers the entire link from the central control room to audio extenders and every conference microphone unit. It not only solves voltage drop issues in long-distance transmission but also guarantees pristine audio quality through physical isolation.
