Active Optical USB 3.1 Cable by HP POLY — model 875H3AA, 25 m, USB-A to USB-C, slim connectors, black

HP POLY Active Optical USB 3.1 Cable (25 m) is a long-reach USB-A to USB-C active optical cable engineered to maintain USB 3.1 performance over extended distances. The cable combines an optical signal path with slim, space-saving connectors in a black finish to support high-speed data transfer while reducing signal degradation typical of long copper runs. It is intended for professional AV, conferencing, docking and peripheral extension scenarios that require a reliable USB 3.1 connection across a 25-m span.

Advantages

The active optical design preserves signal integrity and USB 3.1 throughput across 25 metres, enabling stable, high-speed connections where passive copper cables would fail. Slim connector housings simplify routing through crowded racks, cable conduits and tight desk cutouts. The cable’s construction reduces electromagnetic interference and attenuation compared with long copper alternatives, providing more consistent performance for data-intensive peripherals and AV equipment.

Suitable for

• Extending USB-A host connections to USB-C devices up to 25 m away
• Conference room setups: cameras, speakerphones and docking stations
• AV installations where long, high-speed USB links are required
• Workstations or labs that need reliable peripheral extension without signal loss

When it may not be suitable

This active optical cable provides USB 3.1 data connectivity but is not a power delivery substitute for high-current charging; devices requiring significant charging current may need a dedicated power source. The cable’s optical design is optimized for data; specific audio/video devices or protocols that depend on alternative signal types or proprietary power profiles may require different cabling solutions.

Key specifications

• Length: 25 metres
• Connector types: USB-A (host) to USB-C (device)
• USB standard: USB 3.1 data support
• Connector style: slim profile housings for tight routing
• Color: black
• Cable type: active optical cable (AOC) for long-distance data transmission

How to use

Connect the USB-A end to a compatible host or host port and the USB-C end to the target device. Ensure both host and device support the required USB 3.1 modes for expected throughput. Route the slim connectors through cable channels or tight spaces as needed; avoid tight bends near the connectors and follow standard cable management practices. If a device needs external power, connect the proper power adapter directly to the device rather than relying on the cable for high-current charging.

What to consider before purchase

• Confirm host and device USB versions and compatibility with USB 3.1 data modes
• Verify whether your device requires separate power delivery beyond what the cable can provide
• Plan cable routing to accommodate a 25 m length and avoid excessive bending or kinking
• Ensure the slim connector dimensions suit your equipment’s port clearance

Usage recommendations

For stable performance, use this cable for data-intensive peripherals and AV endpoints where long runs are necessary; secure the cable along a path that avoids sharp bends and strong EMI sources, and provide separate power to devices with higher charging demands.
