Telecommunications Coaxial Cables

Telecommunications Coaxial Cables

"Telecommunications Coaxial Cable Series"​, covering core specifications from ​1/4" to 1-5/8"​, is optimized for communication scenarios such as ​5G base stations, satellite communications, and data center interconnects, providing customers in the communications industry with stronger transmission solutions tailored to their needs.

Demand and Product Positioning

With the deepening of ​5G commercialization, acceleration of ​satellite internet deployment, and expansion of ​data centers, the requirements for transmission cables in the communications industry are trending toward ​high-frequency low-loss, anti-electromagnetic interference, and complex environment adaptability. Traditional coaxial cables often face challenges like ​signal attenuation in high-frequency scenarios​ and ​sensitivity to interference. The newly introduced telecommunications series addresses three core pain points through in-depth research on communication link demands:

​1. High-Frequency Transmission Loss: Optimized insulation layer materials and structural design for ​5G millimeter-wave (26-40GHz)​​ and ​satellite communications (Ku/Ka bands)​​ to reduce signal attenuation.
​2. Anti-Interference Capability: Upgraded shielding structures to mitigate interference from electromagnetic environments (e.g., radar, industrial equipment) around base stations.
3.Complex Environment Adaptability: Enhanced resistance to temperature, weather, and mechanical stress to ensure long-term stability in outdoor base stations, data centers, and other scenarios.

Product Specifications and Application Scenarios

Based on the ​​"core network-access network-terminal"​​ full-link requirements of the communications industry, the series introduces ​four segmented specification groups​ to cover multi-scenario applications from ​micro base stations to satellite ground stations:

Core Design Objective

1/4"S, 3/8"S, 1/2"S 5G micro base station indoor distribution, small device connections Ultra-flexible design (bending radius ≤5cm), supports ​28GHz high-frequency low-loss transmission
7/8"S, 1-1/4"S, 7/8"AL 5G macro base station antenna feeders, AAU connections Semi-rigid aluminum tube outer conductor (compressive strength ≥1500N), adapts to base station wind load requirements
1-5/8"S, 1-5/8"AL, 1-1/4"AL Satellite ground station feed sources, VSAT terminals Low loss (≤0.25dB/m at 12GHz)​, supports high-frequency beamforming
1/2"AL, 3/8"SL, 7/8"L Data center high-speed device interconnects, optical module connections Shielding effectiveness ≥-90dB, reduces signal crosstalk, supports ​100G/400G Ethernet

Example: The 7/8"AL feeder adopts a semi-rigid aluminum tube outer conductor capable of withstanding ​30m/s wind loads​ on base station antennas. The 1-5/8"S satellite communication cable features a physically foamed PE insulation layer with stable dielectric constant, minimizing signal attenuation during satellite transmission.

Technical Implementation: Materials, Processes, and Testing

The performance of the telecommunications series is ensured through stringent control over the entire process of ​​"materials-process-testing"​:

Material Selection:

  • Center conductor: ​99.99% high-purity oxygen-free copper​ (conductivity ≥58.0MS/m) to reduce high-frequency skin effect losses.
  • Insulation layer: Imported physical-foamed PE with uniform bubble size controlled within ​​±5μm​ and dielectric tangent loss (tanδ) ≤0.0003.

Production Processes:

  • High-precision extruders (diameter tolerance ±0.005mm) and laser measurement systems ensure concentricity between insulation layers and outer conductors ​​≤1%​.
  • Semi-rigid cable outer conductors undergo ​​"cold drawing + aging treatment"​​ processes, achieving an ​anti-fatigue lifespan of 120,000 bending cycles​ (industry standard: 100,000 cycles).
