Extron USBC Pro 8K/12 (part number 26-748-12) — a 12 ft (3.6 m) active hybrid optical-copper USB-C cable carrying 8K/30 video, USB 2.0 data and up to 60 W of power on a single lead.

Passive USB-C cables run out of headroom well before twelve feet at 8K. This one gets around that by putting the high-speed lanes onto optical fibre while keeping copper for power and low-speed signalling, so a laptop at a conference table can drive a display across the room with no extender box and no separate power brick. All four DisplayPort lanes stay available, which is what makes a full 7680x4320 image at 30 Hz possible instead of a 4K compromise. Power flows either way, so whichever end has the supply feeds the other.

Key Capabilities

• DisplayPort Alt Mode 1.4 across four lanes, 32.4 Gbps total at 8.1 Gbps per lane, with MST support.
• Resolutions to 7680x4320 at 30 Hz, and 4096x2160 at 60 Hz with 12-bit colour.
• USB 2.0 and 1.1 compatible, with data at up to 480 Mbps.
• Bidirectional USB Power Delivery to 60 W, with no external supply needed.
• 0.26 in (6.5 mm) outer diameter and a 0.79 in (20 mm) bend radius for tight cable paths.
• EDID and HDCP 2.3 encrypted signals pass through; contacts are gold plated.
• A red ring marks the host end and the moulded connectors are labelled for direction.

Where It Is Used

Huddle rooms and conference tables feeding wall displays, lecterns and classroom teaching walls, USB-C docking positions in open-plan offices, broadcast and production edit bays, and clinical or laboratory workstations that want one cable for picture, peripherals and charging.
