Extron USBA Pro P/15 (part number 26-728-15) — a 15 ft (4.5 m) plenum-rated active extension cable that carries SuperSpeed USB 3.2 signals and power from a host to a USB peripheral.

Standard USB-A cables give up long before 15 feet at 5 Gbps. This one uses glass multimode fibre for the SuperSpeed lanes, with copper alongside carrying USB 2.0, USB 1.1 and the 5 V supply. Termination is a male USB-A plug at the host and a female USB-A socket at the peripheral end, so it behaves as a straight extension rather than a device-specific cable. A blue LED at the female end confirms the host is supplying power — useful when the peripheral is out of reach behind a display.

Key Capabilities

• SuperSpeed USB data at 5 Gbps under USB 3.2 Gen1, with USB 2.0 and 1.1 fallback.
• Supplies 5 V at up to 900 mA, or 4.5 W, to the connected peripheral.
• NEC CMP plenum jacket, so the run can pass through open air spaces.
• Powered by the host computer, drawing 2.25 W for its own conversion circuitry.
• A pigtail is provided for an external supply when the peripheral needs more current.
• Blue LED on the female connector reports host power presence at a glance.
• 0.24 in (6 mm) diameter with a 0.79 in (20 mm) bend radius.

Where It Is Used

Conference rooms with wall or ceiling USB cameras, classroom document cameras and capture appliances, reception and kiosk touch screens, laboratory instruments away from the host PC, and any installation where a USB device must sit further from the computer than a passive cable allows.
