Compare USB Cable Solutions for Your Project
Start with the host, device and installed cable length
Use this guide to compare USB connectors and copper or active optical connections for cameras, machine vision, meeting rooms and other USB peripherals. A cable must match the required USB generation, endpoint roles and device power demand.
| Project need | Cable solution | Recommended model | Check before ordering |
|---|---|---|---|
| Short connection to equipment with a USB-A device/service port | USB 3.0 copper; up to 5Gbps | STQG-4800 | Confirm the equipment supports a USB-A male-to-male host-to-device connection. Do not connect two computers. |
| Long-distance USB-A host-to-device connection | USB 3.0 active optical; up to 5Gbps and 100m | SUAM-3000 | The remote device or hub needs its own power supply. Confirm USB generation and endpoint roles. |
| Camera or equipment with a USB-B port | USB-A to USB-B active optical; up to 10Gbps and 15m | SUAB-3120 | Confirm the device connector, USB 2.0 fallback requirement and power budget; listed device power is up to 5V/900mA. |
| Machine-vision camera with a Micro-B port | USB-A to Micro-B active optical; up to 10Gbps and 15m | SUMB-3120 | Confirm Micro-B connector geometry, locking screws and camera power demand. |
| USB-A computer to a USB-C peripheral | USB-A to USB-C active optical; up to 10Gbps and 15m | SUAC-3120 | Confirm host/device ends, USB 2.0 compatibility and the peripheral power demand. |
| Long-distance USB-C data connection | USB-C to USB-C active optical; up to 10Gbps and 30m | SCDC-3100 | Data connection only: no DP Alt Mode video output. Listed remote-device power is up to 5V/800mA. |
| One USB-C link for data, display and power | Full-function USB-C active optical; up to 10Gbps, 60W PD and 10m | SCFC-3120 | Requires compatible DP Alt Mode endpoints for video. Install source/display ends correctly. See the full-featured USB-C guide. |
Copper, active extension or active optical?
- Copper: consider it for short, accessible connections. Confirm the usable length at the required data rate and power load.
- Active extension: consider it when an existing connection needs extra reach. Check hub support, total channel length and external power requirements with the project team.
- Active optical: consider it for longer installed runs or demanding routing. Optical data transmission does not guarantee USB 2.0 fallback, high-power charging or video on every model.
Check compatibility before selecting a model
- Identify the computer/host and peripheral, including exact equipment model numbers.
- Record the connector at each end: USB-A, USB-B, Micro-B or USB-C.
- Specify the required USB data rate and whether USB 2.0 devices must also work.
- Measure the complete installed route, including rack access and service loops.
- State the peripheral power demand and whether local power is available.
- Confirm bend radius, locking connectors, installation direction and any moving-cable requirements.
Frequently asked questions
Does a longer cable provide the same functions as a short cable?
Not automatically. Compare data rate, backward compatibility and power delivery for the selected model and length.
Can USB-C data cables also connect a display?
Only when the cable and connected equipment support the required video function. For function-by-function comparison, see our USB-C cable selection guide.
How do I request a suitable cable?
