1394.b long cables
UL VW-1 No.20276 80degrees 30V
The first long cable in the industry to clear the IEEE1394.b standard
Outline
- This IEEE1394.b cable supports a transmission speed of 800Mbps.
- The maximum transmission distance is 10m (standard 4.5m).
- The special cable construction reduces attenuation, thus realizing a transmission distance of about twice the standard distance.
- The special cable construction in combination with the shield realizes noise immunity which is suitable for a factory automation environment.
- Conforms to UL standard VW-1 (Style No.20276 80degrees 30V).
