Extend an HDMI connection through ceiling and in-wall pathways with a 50 m hybrid active optical cable rated CMP for plenum spaces. StarTech 8K-A-50M-HDMI-CABLE combines optical transport with HDMI connectors to carry high-bandwidth AV signals farther than a conventional passive copper HDMI run. Its 4.6 mm outside diameter supports routing where cable pathway space is limited. The cable supports HDMI 2.1 signaling at up to 48 Gbps, including 8K 60 Hz, 4K 120 Hz, and 1440p 240 Hz video formats. Dynamic HDR10 with 12-bit processing, HDR10+, DSC 1.2a, HBR3, and HDCP 2.3 support address modern display and source requirements. Audio support includes eARC and 7.1 surround sound, allowing one cable to carry display video and return-channel audio in compatible installations. A unidirectional construction requires the cable ends to be connected in the correct source-to-display orientation. Gold-plated connectors are rated for more than 10,000 insertions, while aramid reinforcement adds tensile strength for long cable pulls. HDMI 2.0, HDMI 1.4, and HDMI 1.2 compatibility supports installations that need to connect newer cable infrastructure to earlier-generation HDMI equipment.
