Maximum suggested IEEE-1394 cable lengths
Last Revision Date: 5/27/2014
The IEEE-1394 standard specifies the following maximum cable lengths:
Bus Type | Cable Type | Max Length | Speed Limitations |
1394a | 4-pin or 6-pin shielded TP copper | 4.5m | 400Mbps |
1394b | 9-pin shielded TP copper | 4.5m | 800Mbps |
1394b | Unshielded TP | 4.5m | 800Mbps* |
1394b | Unshielded TP | 100m | 100Mbps* |
1394b | Glass optical fiber (GOF) | 100m | (Check with the manufacturer for speed/distance limitations)* |
1394b | Plastic optical fiber | 50m | (Check with the manufacturer for speed/distance limitations)* |
Some manufacturers sell cables that exceed the above specifications. In some cases, longer (e.g. 20m) cables can only be achieved by reducing the maximum bus speed to S100. Refer to "Extending the Distance Between between a Camera and the Controlling Host System" for information on extending the distance between a camera and the host system.
* We do not manufacture any cameras that support this interface.
