Extron DP Pro P/125 (part number 26-727-125) — a 125 ft (38 m) active hybrid optical-copper DisplayPort cable from the DP Pro Plenum Series, NEC CMP rated.

By 125 feet the question is no longer whether fibre is needed but whether the install can afford the complexity of an extender pair. This cable answers with a single plug-and-play assembly: multimode optical fibres for the four DisplayPort lanes, 24 AWG tinned copper for the auxiliary and hot-plug lines, and active electronics moulded into the connectors that run on 375 mW pulled from the source and sink. Throughput tops out at 32.4 Gbps, enough for 8K at 30 Hz with full 4:4:4 chroma, and the CMP jacket is legal above a return-air ceiling.

Key Capabilities

• DisplayPort 1.4 with HDCP 1.4, HDCP 2.3 and HDR; EDID, CEC and 32 audio channels carried.
• Maximum video data rate of 32.4 Gbps, 8.1 Gbps per lane.
• 8K (7680 x 4320) at 30 Hz with 4:4:4 chroma, or at 60 Hz with 4:2:0, 8 bits per color.
• Frame rates from 24 Hz to 240 Hz within the data rate ceiling.
• 0.18 in (4.6 mm) outer diameter with a 0.79 in (20 mm) bend radius.
• NEC CMP plenum rated; CE and UL-CMP compliant.
• Highly resistant to EMI and RFI — the high-speed lanes are glass, not copper.

Where It Is Used

Very long single-cable video runs: stadium and arena displays, transport terminal signage, large auditorium projection, multi-floor riser links between a head-end rack and a remote display, and industrial or utility control centres where electrical noise rules out long copper.
