Furutech FX-Alpha-Ag Reference Pure Silver (25AWG) 75Ω Coaxial Cable (per metre)

Furutech FX-Alpha-Ag Ensures Precision Signal Transmission with Pure Silver Conductors

Furutech FX-Alpha-Ag 75Ω Coaxial Cable (Per Metre) is a high-purity, audiophile-grade coaxial cable engineered for critical digital audio, high-frequency RF, and broadcast-grade video signal applications. Offered by the metre for complete flexibility, this precision cable allows installers and system designers to cut exact lengths without compromising performance, signal integrity, or electrical consistency.

FX-Alpha-Ag Uses α (Alpha)-Treated Pure Silver Conductors for Signal Purity

FX-Alpha-Ag Coaxial Cable features Furutech’s α (Alpha)-Pure Silver Conductor, made from seven strands of ultra-fine 0.18 mm silver wire. This 25 AWG construction (0.178 sq.mm) provides a carefully balanced geometry to reduce skin effect and enhance high-frequency signal transfer.

Each conductor undergoes Furutech’s exclusive α (Alpha) processing, a two-stage treatment that cryogenically freezes and then demagnetises the silver to refine its crystalline structure. This process significantly reduces internal distortion, dielectric interaction, and magnetic hysteresis, allowing signals to pass through with exceptional accuracy and clarity. The result is reduced jitter, improved phase coherence, and greater tonal transparency, especially critical for word clock lines, digital audio interfaces, and SPDIF transmissions.

FX-Alpha-Ag Delivers Consistent Timing with Dual-Layer Dielectric Insulation

Furutech FX-Alpha-Ag 75 Ohm Cable integrates a dual-insulation system engineered for minimal signal loss and high propagation velocity. The inner fluoropolymer insulation offers an exceptionally low dielectric constant and high thermal stability, which enhances signal speed and maintains structural consistency over long periods of use.

Surrounding this is a secondary polyethylene foam layer, which introduces controlled air spacing to reduce capacitance and minimise signal reflections. This precise dielectric configuration results in a transmission delay time of 3.80 ± 0.10 ns/m, ensuring superior timing stability across critical digital signal paths.

FX-Alpha-Ag Combats EMI with α-Treated Shielding Structure

FX-Alpha-Ag Per Metre Coaxial Cable employs a high-performance shielding system designed to block electromagnetic interference in electrically dense environments. The dual-layer shield includes a PET/aluminium foil layer and a dense 0.10 mm α (Alpha)-treated silver-plated copper braid, which work together to suppress both low and high-frequency noise.

This shielding ensures that signals remain unaffected by crosstalk, EMI, or RFI in studio racks, home theatre setups, or professional AV systems. Whether used for SPDIF coax, video sync, or master clock distribution, the cable maintains accurate 75Ω impedance across its full length.

FX-Alpha-Ag Offers Flexible Installation with Robust Outer Sheath

Furutech FX-Alpha-Ag 25 AWG Coaxial Cable is enclosed in a green flexible PVC outer sheath, offering a combination of physical resilience and ease of handling. With an overall diameter of 8.0 mm, the cable maintains a manageable bend radius, making it well-suited for installations that require routing through confined spaces, patch panels, or rack systems.

Sold by the metre, FX-Alpha-Ag provides the flexibility to create custom cable runs for precise system layouts—eliminating the compromises often introduced by pre-cut lengths or unnecessary joins.
