Furutech FX-Alpha-Ag Reference Pure Silver (25AWG) 75Ω Coaxial Cable (50M Roll)

Furutech FX-Alpha-Ag Provides Precision Transmission Using Pure Silver Conductors

Furutech FX-Alpha-Ag 75Ω Coaxial Cable (50M/Reel) is a high-specification coaxial signal cable engineered to deliver ultra-low-loss transmission with impeccable timing precision. Designed for professional-grade digital audio, word clock distribution, RF interfacing, and high-definition video signal applications, this cable prioritises signal fidelity and impedance stability across its full 50-metre reel.

FX-Alpha-Ag Features Pure Silver Conductors with α (Alpha) Processing

FX-Alpha-Ag Coaxial Cable uses Furutech’s acclaimed α (Alpha)-Pure Silver Conductor, composed of seven strands of 0.18 mm high-purity silver wire. Each strand undergoes the proprietary α (Alpha) treatment—combining deep cryogenic processing and controlled demagnetisation—to reduce microstructural impurities and stress. This advanced metallurgy enhances signal smoothness and significantly lowers resistance, enabling higher transmission speeds with reduced phase distortion.

This 25 AWG configuration (0.178 sq.mm) strikes an ideal balance between conductor mass and skin effect mitigation, making it highly effective for accurate digital signal transmission, especially in environments where jitter and timing precision are mission-critical.

FX-Alpha-Ag Maintains Signal Precision Through Advanced Dielectric Design

Furutech FX-Alpha-Ag 75 Ohm Cable features a dual-layer dielectric system that maximises velocity factor while reducing capacitive losses. The inner fluoropolymer insulation offers excellent thermal stability and ultra-low dielectric constant properties, which reduce time delay variance and signal reflections. Surrounding this, a polyethylene foam layer introduces low-density dielectric support, improving high-frequency transmission linearity and impedance consistency throughout the cable’s full length.

These layers work in tandem to achieve a transmission delay time of 3.80 ± 0.10 ns/m, ensuring synchronisation accuracy in word clock, broadcast, and master clock routing scenarios.

FX-Alpha-Ag Delivers Shielded Reliability in High-Interference Environments

FX-Alpha-Ag Coaxial Reel incorporates robust shielding to prevent signal degradation due to external interference. Its dual-layer shield comprises a PET/aluminium foil wrap paired with a 0.10 mm α (Alpha)-treated silver-plated copper wire braid, which effectively suppresses EMI and RFI.

Whether deployed in professional AV racks, recording studios, or high-frequency RF environments, this shielding structure ensures the cable remains immune to signal pollution and crosstalk—supporting full-specification 75Ω system performance in even the most demanding signal chains.

FX-Alpha-Ag Combines Flexible Form Factor with Durable Sheathing

Furutech FX-Alpha-Ag 25 AWG Silver Coaxial Cable is enclosed in a green flexible PVC sheath, offering resistance to kinks, abrasions, and environmental wear without compromising bend radius or ease of installation. The 8.0mm outer diameter supports straightforward integration into cable management systems, while its structural flexibility makes it ideal for both temporary field setups and permanent installations.

This reel format offers 50 metres of uninterrupted, high-purity coaxial cable, ensuring installers and engineers can tailor cable lengths precisely without introducing signal breaks or added termination points.
