What is the maximum cable length for camera link?

The ​maximum cable length for standard CameraLink​ depends on the configuration and data rate, but here are the key specifications:

​Standard CameraLink Cable Lengths​

​Configuration​ ​Max Recommended Length​ ​Notes​
​Base (2.04 Gbps)​​ ​10 meters​ (33 ft) Most common limit for reliable signal integrity.
​Medium (4.08 Gbps)​​ ​7–10 meters​ Shorter lengths recommended for higher speeds.
​Full (6.8 Gbps)​​ ​5–7 meters​ Signal degradation increases at max bandwidth.
​Extending CameraLink Beyond 10m​

1. Using Repeaters (Signal Boosters)​​

A ​CameraLink repeater​ can extend the range up to ​20–30m total​ (10m + repeater + another 10m).

Example: ​DALSA Xtium™ CLHS Repeater Module.

2. Fiber Optic Extenders​

Fiber-optic CameraLink extenders​ (e.g., ​BitFlow Fiber Optic Link) can push signals ​100m–2km+​.

Converts LVDS signals to optical, eliminating EMI issues.

3. CameraLink HS (High Speed)​​

The newer ​CameraLink HS​ standard supports ​longer distances natively​ (up to ​15m at 3.125 Gbps/lane).

​Factors Affecting Max Length​

1. Cable Quality:​​ Shielded twisted-pair (STP) with low skew is critical.

2. ​EMI Environment:​​ High interference may reduce reliable distance.

​3. Data Rate:​​ Higher speeds (Full config) require shorter cables.

​Comparison with Other Standards​
​Interface​ ​Max Length (No Extenders)​​ ​With Extenders​
​CameraLink​ 10m (Base) 30m (repeaters) / 2km (fiber)
​GigE Vision​ 100m 10km+ (fiber)
​CoaXPress​ 40m (CXP-6) 100m+ (active cables)
​USB3 Vision​ 3–5m 10m (active USB)
​Best Practices​

✔ Use ​high-quality MDR-26/HD-26 cables​ (e.g., ​Tekscan CL Series).
✔ For >10m, consider ​fiber optic conversion​ for zero signal loss.
✔ Avoid sharp bends or kinks in cables to maintain signal integrity.
