The Ugreen AV108 uses advanced optical fiber to transmit the signal via light, completely eliminating any electromagnetic (EMI) or radio frequency (RFI) interference. Unlike traditional copper cables, optical transmission ensures that the sound remains pure and free from "noise", offering the highest possible fidelity for uncompressed PCM audio, as well as for multichannel Dolby Digital and DTS systems.

This model stands out for its excellent build quality, featuring an outer layer of braided nylon in gray color. This shielding protects the sensitive optical fiber from bending, pressure, and everyday wear, while remaining flexible enough for easy installation. The connector shell made of aluminum alloy offers extra durability, making the cable a long-term investment for your audio system.

The cable connectors are 24K gold-plated, ensuring optimal contact and protection against corrosion. Each end features removable rubber dust covers that protect the optical lenses from scratches and dirt when the cable is not connected. This attention to detail ensures that the transmission quality remains unchanged, offering consistent performance every time you use it.
