SYNERGY21 S215913 HDMI 2.1 aktívny optický kábel 20m 8K60Hz

This 20-metre active optical HDMI cable carries the full HDMI 2.1 feature set over distances where copper cables simply cannot. Because the signal travels as light through fibre, 48 Gbps, 8K60 and 4K120 remain stable without signal boosters or repeaters.

Highlights

• HDMI 2.1 with 48 Gbps bandwidth
• Active Optical Cable (AOC) – immune to EMI, no signal loss over 20 m
• Supports 8K 7680×4320 @ 60 Hz and 4K 3840×2160 @ 120 Hz
• Dynamic HDR (HDR10+, HLG), eARC, VRR, ALLM, QFT, QMS
• HDCP 2.3, directional (source/display marked), bus-powered

In daily use

Connect an 8K TV, gaming PC or console across a room without visible cables or signal degradation. The slim fibre core makes the cable lighter and more flexible than copper equivalents, and the active electronics draw power directly from the HDMI port – no external supply needed.
