| Revel,
It's nice to hear from you in New Zealand. Here's what I know about Category 6, there has been a lot of noise and
various companies using the term. It is not a TIA/EIA 568 standard. There are some companies attempting to push
the concept forward and I understand that some group in Germany has or is publishing a Category 6 specification.
I also understand the the distributor ANIXTER is publishing thier purchase spec on Category 6.
We are looking into this to see if we can turn up anything else on this. Chris DiMinico in our group is a member
of the TIA/EIA group responsible for the 568A standard that issued the Catagory specifcations. Chris has told me
that the committee is still working to complete the Catergory 5 specification and no work is being done on
Category 6. At this time most of this is marketing hype, various companies testing their components beyond 100
MHz and using this to position thier products. At this time the PHY standard for products specify Category 5
performance for the twisted pair interfaces.
Lucent has punblished papers documenting support of 622 MHz using multipair Category 5 cabling. If your customer
is interested in supporting transmission bandwidths beyond 100 MHz they shoud consider installing Optical Fiber.
That will support thier future needs with minimum risk.
When more information becomes available I will add it to this note. Let me know if you have any other questions.
Please send us any more information you can get on what is being offered by AT&T or Lucent.
Thanks,
Norm
