It wasn't that all the components were necessarily manufactured by one company, but that the company offering the warranty had actually performed testing of all the components to ensure interoperability and reliability. At Leviton we brought in products from manufacturers and did compliance...

IMHO if you really need 10 gig, fiber is the way to go. I have my doubts about ever being able to reliably and cost effectively do 10 gig over copper. Since it looks like cat 7 will be a screened and shielded 4 pair the cost of cable and termination I believe will make fiber the winner. Sort...

Well, frankly I buy American made patch cords from my local supplier. They are manufactured in AZ by a company called Gruber Industries. http://www.gruber.com/ I have been using them for about 4 years now and wouldn't use anything else. Price is right as is the quality. They are made using...

TO: Wires...... You can't test 25 pair because a certification test requires testing EACH PAIR AGAINST EVERY pair in the jacket. Show me a tester that can do that. All certification testers, which are the only ones that run all required tests, run 4 pairs only. Next time you want to call...

The comments were regarding Cat 5, and frankly, why would you do things 2 different ways? Learn the right way and do everything the same, as Skip stated, he started doing it with cat 3, and does everything that way, you build repetition so you can do it without having to think about what you are...

gcunning Your not correct in your summation of the difference between cat 5 and cat 6. Having been an Applications Engineer for a major manufacturer of Voice and Data products, there is more to it than just twists. Especially in the jacks. The speeds at which cat 6 transmits makes NEXT a very...

Jim The post you put up is not a proper illustration of punching down cat 5 on a 66 block. That style of termination would fail a BICSI Installer class. To be cat 5 compliant, the pairs must remain twisted right up to point of termination. In those illustrations the pairs are untwisted OUTSIDE...

Forgot one important point. Since cat 3 is really not a well twisted pair cable, having a 25 pair try to transmit data is comparable to trying to carry on a conversation in a very crowded elevator. The proximity of the conductors and the lack of twist to counteract crosstalk is most likely a...

Please don’t take my questions the wrong way, but since I am not on-site I have to ask. Regarding the 25 pair Cat 3, are you really trying to run data over a 25 pair? I would be willing to make a large wager none of this was ever tested. Since you can not test 25 pair cable for data. What...

What would be the point? You would only have a Cat 5 system and you would have spent more money on the jacks than a cat 5 system is worth. The overall system is rated at the performance level of the weakest link, which in the case you describe is Cat 5. Put another way, sure it's ok, but you...

That is correct, those are the changes made for GigaBIX as I mentioned earlier. Richard S. Anderson, RCDD http://www.servamatic.net

If you know the measurements of the BIX desi-strips you can set Word up using the labels function for any label you might need. Then get a good paper cutter, the kind that rolls and cuts, not the chopping type. You can set it up any way you want then. Richard S. Anderson, RCDD...

READ 770-53 Yes you can substitute OFNP in place of OFNR but not visa versa. Questions like this are code questions and should be made after reading the National Electric Code. There is a chart of substitutions in the code book in the sections I have mentioned, follow it. Anytime you have a...

Why would you need to know the chemical content? If you are working in a plenum area, you must install plenum rated cable, and that does NOT mean LSZH here in the US. LSZH is not recognized by the NEC for cable insulation in plenum areas. For copper communications cable see NEC 800.50 For...

ETL Semko does a great deal of testing for manufacturers as a disinterested third party. http://www.etlsemko.com/ Richard S. Anderson, RCDD http://www.servamatic.net

If you set your OS to show the icon in the system tray, you can hold your mouse over it and it will tell you what speed you are connected. I know XP does this as does Win 2000 Server. Right click on the LAN connection and select properties, then check "Show icon in taskbar when...

That is the way BIX Cat 5 was to be done according to manufacturer specs. Now with GigaBIX (Cat 5e) you don't remove that much jacket. Gigabit has a hard time running if you remove to much jacket due to return loss and NEXT. You can find BIX almost anywhere, but it is dominant in Canada. Always...

What type of blocks were they terminated on? The Cat 5 BIX block called for 14" of sheath removal. Since you are in Canada, I would assume it is a BIX but if not, then it sounds like poor craftsmanship, the standard says only as much as needed to affect termination, or per manufacturers...

What operating system are you using? Richard S. Anderson, RCDD http://www.servamatic.net

I was using direct burial cable in Cat 5e 2 years ago, Commscope was the first that I know of to manufacture it. I have often found Graybar people lacking in their knowledge of data comm products. To be fair, that is sadly true with far too many distributors that try to sell products in our...
