Extron HD Pro P/25 (part number 26-726-25) — a single-cable 4K/60 HDMI link that runs 25 ft through plenum airspace without an external power supply.

The HD Pro Plenum Series moves HDMI over a hybrid build: multimode optical fiber carries the high-speed video lanes while tinned 28 AWG copper handles the low-speed housekeeping signals. That split lets a 25 ft (7.6 m) run deliver full-bandwidth 4K instead of the softened, marginal picture that long passive copper often produces. The jacket measures just 0.16 in (4 mm) across, so the cable pulls easily through crowded conduit and lies flat behind a wall plate or display bracket.

Key Capabilities

• Throughput of up to 18.0 Gbps, enough for 4096x2160 at 60 Hz with 4:4:4 chroma
• Built to HDMI 2.0b and HDCP 2.3, with HDR signals passed straight through
• Carries PCM 8-channel, Dolby Digital True HD and DTS-HD Master Audio soundtracks
• EDID, HDCP and CEC messaging travels end to end on the copper conductors
• Takes all of its operating power from the connected HDMI source; no injector or brick
• UL-CMP jacket rating for installation in return-air plenum spaces

Where It Is Used

A 25 ft length fits rack-to-display drops in conference rooms, huddle spaces and classroom lecterns, where the cable exits a credenza, crosses a ceiling void and terminates at a flat panel or short-throw projector. Diagnostic reading rooms, nurse stations and small control positions use the same run length to reach a wall-mounted medical or command display.
