Underwater high-definition coaxial cable

underwaterHigh definition coaxial cableexcellentPerformance comes from its precise four layer structure. The central conductor, as the core of signal transmission, is usually made of high-purity copper or silver plated copper to ensure stable flow of high-frequency current; The insulation layer surrounds the conductor, effectively isolating external interference and maintaining signal integrity.

withThe popularization of technologies such as 4K/8K ultra high definition video and 5G communication has put forward higher requirements for the bandwidth and anti-interference ability of transmission media. Coaxial cables continue to play an important role in high-definition signal transmission due to their unique structural design.

underwaterHigh definition coaxial cable adoptsThe four layer structure design of 'central conductor insulation layer shielding layer outer sheath':

Central conductorUsing high-purity oxygen free copper or silver plated copper with a diameter of 0.5-2.5mm, responsible for high-frequency signal transmission.

insulating layerSelect low dielectric constant physical foamed polyethylene (PE) with a thickness of 0.3-1.2mm to ensure impedance stability

shielded layerDouble layer shielding structure (aluminum foil+tin plated copper mesh), with a shielding efficiency of over 90dB，The metal shielding layer is like a sturdy barrier, and the woven copper mesh or aluminum foil structure can greatly suppress electromagnetic interference, prevent signal leakage or distortion; The outermost sheath is made of durablePVCorPEMaterial wrapping, resistant to physical damage and environmental corrosion, ensuring long-term durability of cables. This design not only optimizes the signal transmission path, but also significantly improves anti-interference ability, providing a pure transmission channel for high-definition content.

outer sheathFlame retardant PVC or LSZH material, compliant with UL94 V-0 flame retardant standard

Adopting a dual shielding structure can effectively suppress:

Electromagnetic interference (EMI) attenuation ≥ 40dB

Radio frequency interference (RFI) shielding effectiveness ≥ 90dB

共模噪声抑制比 （CMRR）≥60dB

Transmission distance advantage：

The transmission distance without relay can reach 300m

By using low loss cables (such as LDF5-50A), it can be extended up to 500m

Through equalizer compensation, the transmission distance of 4K signal can reach 200m

Dear friends,underwaterHigh definition coaxial cables have become an invisible bridge for modern communication due to their exquisite structure, powerful functions, and wide applications. It is not only the crystallization of technology, but also a catalyst for innovation. Let us join hands to explore its potential and jointly promote the pinnacle of audiovisual transmission.
