If you're not doing 10GB ethernet, then there's nothing that Cat6 can do that Cat 5e can't. No point whatsoever in spending the additional money on cable and connectors that are more difficult to work with and won't gain you anything in regards to performance. Stick with 5e.

Your ungrounded shield is going to turn into an antenna - which will in turn induce RFI into your signal. You should only use STP cable if you're also installing shielded jacks and patch panels and do all the bonding and grounding necessary to make the system function properly. UTP is the best...

Unfortunately, "Keystone" means different things to different people. While all keystone-type jacks have the same basic configuration and dimensions, there are frequently small variations in design from manufacturer to manufacturer. Additionally, it's very difficult to get an exact color match...

The issue isn't whether you're only running a limited number of cables or a large number. The issue is that NEC requires plenum-rated cable in plenum spaces because of life/safety issues. If you feel the need to gamble with someone else's health/life, then by all means break the law and try to...

Does anyone know of a source for repair parts (electrodes and batteries) for Aurora fusion splicers? Their website is shut down and phones disconnected. Thanks in advance for any help you can offer.

Dexman - Genesis still manufactures a 2-pr Cat3 plenum cable. Their part number is 5041. I don't know where you are, so can't suggest a distributor, but you could call them @800/222-0060 for the info. Good luck.

Steve, A) Power is already present in a poured concrete floor. B) Length is approx. 10'. C) Customer has already rejected the wireless solution. Thanks for the reply.

I have a customer who'd like to have a network drop that would retract into the ceiling. Anyone have a solution for this? Thanks in advance.

Ideal has a "Field Application Kit" that has the tools and adhesive required to repair their S-Class and Zoom series fiberglass tapes. It also comes with replacement eyelets and leaders. Part number is 31-156. Most electrical distributors should be able to get it for you.

The 850 and 1300 numbers refer to the wavelength of the light source. These are the 2 common wavelengths used for multimode fiber. If your fiber is singlemode, you would probably be using either 1310 or 1550. Many installation require the fiber to be tested at both wavelengths, but you may want...

Sorry, guys. I just saw the thread on the same subject from a few days ago. Should have checked first. If there are any other ideas, I'd like to hear about them. Thanks.

Here's an easy one for the cable installers. I'm looking for a meter to read the db level on cable TV lines as they enter the house. Don't need much in the way of whistles and bells - just a basic meter. Any recommendations are appreciated.

Daron, In your post, you cite 568B as allowing 2 switches to be connected together. There is no problem with that scenario. I was addressing the issue of having 5 hubs and 4 switches between end points. This seems to me to be clearly outside the 568B standard.

You need to be aware that cascading hubs/switches, etc., isn't an approved EIA/TIA-568B cabling method. While it may be OK as far as IEEE standards are concerned, it's going to take you outside the accepted cabling standards for commercial/industrial applications. If this is your own building...
