HDMI Fiber Optic Cable (10m+)
Cáp HDMI quang học tích cực sử dụng sợi quang cho khoảng cách dài (10-30m) không mất tín hiệu. Hỗ trợ 4K@60Hz hoặc 8K với biến thể sợi quang HDMI 2.1. Lý tưởng cho phòng hội nghị và rạp hát tại nhà.
For runs beyond the reach of copper, this active optical HDMI cable converts the signal to light internally, carrying 4K at 60 Hz or, in HDMI 2.1 fiber variants, 8K at 60 Hz across 10 to 30 meters without degradation. The conversion is directional, so the source and display ends are marked and cannot be swapped. Fiber's immunity to electromagnetic interference and its negligible attenuation over distance make it the practical choice where a passive 48 Gbps cable would fail past a few meters. Conference rooms, auditoriums, and whole-room home-theater installs are the typical settings. Prices scale with length, from about $30 to $150.
