Twinax Cable Knowledge
What's the Difference between Active and Passive Twinax Cable?
A passive twinax cable carries a 10 Gig Ethernet signal over short lengths (5m or under, like SFP passive cable) of copper with no additional components to boost signal. An active twinax cable carries a 10 Gig Ethernet signal over long lengths (5m or more, like XFP active cable) of copper with the use of signal boosting technology. Passive copper cables contain no electrical components.
Active copper cables contain electrical components in the connectors that boost signal levels. This makes active copper cables slightly more expensive than passive copper cables; however, they can connect the Converged Network Adapter (CNA) to a top-of-the-rack switch over longer distances than passive copper cables.
With all cables, length and signal strength are always something to look into. For shorter distances it is common practice to use passive cables, they are rated for ranges up to 5m and provide a good working solutions at a great cost.
When the distance between connection points that exceed 5m, it is highly recommended to use active cables to ensure signal is transferred all the way through. The cost may be a bit higher, but the signal is improved and gives peace of mind by creating a trustworthy connection.
Is there a visual difference between active and passive cables? How do I tell if my cables are active or passive?
No. There isn't a truly visual way to tell the difference between active and passive twin-ax cables. The connectors are the same and the cable jackets are identical. So how do you tell? Most manufacturers will have some sort of marking on the cable connector head which will identify the cable as active or passive. There is no way to tell by simply looking at it.
