Feature:1. Applicable: Optical fiber cable is used for connection between DVD, CD player and amplifier; connection between computer and amplifier; connection between PS II, PSIII, HDVD and amplifier; connection between digital TV box and the sound of the amplifier.2. Low Attenuation, Dust-Free Spherical Surface: Digital optical fiber cable's attenuation is less than 0.18dB per meter, and the optical head end is treated with dust-free spherical surface.3. Premium Material: Optical fiber cable uses zinc alloy head with 24K gold plated interface, full copper casing, extra thick cotton mesh with PVC transparent material, full fluororesin fiber conductor core.4. Professional Design: Optical fiber cable uses professionally designed optical fiber audio cable, high flow and frequency width is 5-10 times ordinary optical fiber.5. High Density: Optical fiber cable uses high density wire to improve the service life of the wire, through fatigue test such as pulling, bending and swinging, tightly polished to avoid interference, soft and moderate for easy storage and transportation.Specification:Item Type: Optical Fiber CableMaterial: Zinc Alloy, Silicone, Nylon Braided WireFiber Diameter: Approx. 1mm/0.04inOuter Layer Diameter: Approx. 6.0mm/0.24inFiber Material: PMMAApplication Wavelength: 650nmAttenuation: 0.18dB/mInsertion Loss: 0.40dB/m.Package List:1 x Optical Fiber CableNote:Please allow some errors in manual measurements.
