Extron USBA-C ProMax P/35 (part number 26-758-35) — a 35 ft (10.6 m) plenum-rated active optical cable that links a USB-A host to a USB-C peripheral at 10 Gbps.

Cameras, speakerphones and touch panels increasingly ship with USB-C tails, while the host PC or codec still presents USB-A. Getting between the two at 35 feet is not something a passive cable does. This one carries the SuperSpeed lanes on multimode fibre with copper alongside for power, so 10 Gbps holds across the run and the peripheral still receives 4.5 W. The jacket is NEC CMP plenum rated, which means it can be routed through return-air spaces without conduit in most jurisdictions.

Key Capabilities

• USB 3.2 Gen2 at 10 Gbps, and USB 5 Gbps, over a 35 ft optical run.
• Delivers up to 4.5 W (5 V at 900 mA) to the connected USB peripheral.
• NEC CMP plenum jacket, rated for in-wall and ceiling installation.
• Active circuitry is powered by the connected devices, so no external supply is needed.
• Thin 0.24 in (6.0 mm) diameter with a 1.92 in (49 mm) bend radius.
• Highly resistant to EMI and RFI, suited to data centres and production floors.
• Gold-plated contacts and a reversible USB-C connector at the peripheral end.

Where It Is Used

Conference rooms with ceiling-mounted cameras and table microphones, classroom capture systems, telemedicine carts, control rooms with remote USB panels, and any Pro AV space where the host equipment lives in a rack and the peripheral hangs across the room.
