I am currently doing a cabling job for a small business and I am tasked with installing a new RJ45 wall jack. The office previously had cat5e cables wired through the walls, but my boss has provided me with cat6 keystone jacks. Is the cat5e cable compatible with a cat6 keystone jack? If so, is there somewhere I can find a diagram to properly wire the cables according to the colors on the wire? Any help is appreciated! Thanks everyone.
The color code is the same for both 5e and 6. It should work as long as everything makes contact properly. However that will depend on the gauge of the wire. Gauge can vary between different manufacturers. Try one or two and see how it goes.
With a little of my research, you can try one of the cat 6 Jacks on the cat 5e cable as a trial sometimes it works, the problem may be trying to crimp a cat 6 RJ45 to a cat6 ethernet cable. for fixing the cables to wall jack try this videos they help me out at one time. =TWxKfHhqN2Y and =sHy8mtW9eak .
The only problem I see with using a CAT6 keystone jack with CAT5e in-wall premises wiring is that the marking on the face of the jack says CAT6. This could lead to confusion whereby another user or network tech could be led to believe that the drop is CAT6 when it is not. Relabeling the face of the jack to indicate CAT5e could be beneficial.
EDIT: other users point out, there are different wire gauges. Make sure that the jacks (or plugs) being used are listed as suitable for the gauge of the wire. Using a wire gauge that the jack is not listed for can result in unreliable connections. For example, the Leviton 61110-xx6 eXtreme CAT6 keystone jack is rated to accept 26-22 AWG solid conductors.
My existing reel of for making patch cables is cat5e utp stranded. I made up a few cables and tested them- none of them worked. I recrimped and still nothing. When i check them with a multi-meter not all pins are connected.
I've hand-crimped hundreds, maybe thousands of patch cables. The thing that normally bites you is trying to use modular plugs designed for stranded wire on solid conductor cable or vise versa. They have to match. If not, you'll get enough connectivity for a DVM to show that your pinouts are correct, but not enough to support a 100Mhz signal.
The smaller wire pairs (CAT5) aren't large enough to securely fit in the connectors made for the larger wire pairs (CAT6). You can tell a CAT6 connector (on the left in the below image) by the fact that the wires are staggered at the end of the connector, so that 4 pairs of larger wires will fit.
The second issue is that the conductors in CAT5 RJ45 ends are generally not strong enough to pierce the thicker insulation as well as the thicker wire in CAT6 cables. So even if you can physically fit the cables, you won't get a quality connection.
Cat6 has larger diameter individual conductors as opposed to cat5. You are using cat6 connectors on the smaller diameter cat5. That is most likely your issue. Tolerances on the rj45 connectors are very marginal. If they were compatable with every kind of cable they wouldnt sell different connectors for specific cables. My guess is you got a lucky crimp on a solid cat5 cable. I have heard of people doing this to cut costs. The bottom line is if you want cables with quality connections you cant cut corners and mismatch connectors.
Solid: The 8 crimp pins have fangs that are aligned down the center of each pin.Stranded: The 8 crimp pins stagger their fangs left and right, as to bite more conductive surface and more of the individual conductive strands.
Stranded wire tends to break little strands easily, though they -usually- squeeze against the other non-shielded strands and continue to make -a- connection, their impedance changes a very tiny amount per break. In total, folding a stranded wire repeatedly continuously degrades the connection with each little break, but a solid core exhibits catastrophic failure as one break is a complete break of the conductor.
Compared with Cat 5 and Cat 5e, Cat 6 has more stringent specifications for crosstalk and system noise. Additionally, stranded cable has higher attenuation than solid cable. In my opinion, this is what bit you, assuming that you've ordered connectors that are compatible to stranded cable (and not to solid cable), which would've been my first guess otherwise.
So it turns out that cat6 connectors are not neccessarily backwards compatible with cat5(e) cable. I'm struggling to find sources to cite at the moment- for example suggests they are backward compatible- lots of confusion!
The company we used told me a story of a job they did when they first started using a new set of Cat6 clip-shut terminals. They had connected 1000's of cables to a giant patch panel and they all failed because the clippers they had used did not clip the ends of the cables precisely flush and so 1mm of cable was poking out and when the metal terminal was clipped shut, all the cables touched the metal case and so shorted.
Beside the size difference in diameter between CAT5 and CAT6 cables, the other major difference is SOLID core versus STRANDED cores. For stranded core cables, the teeth on the pins are made to sink into the individual wires (you'll see some labelled as 2-pole or 3-pole to describe the number of teeth on a pin); whereas for solid core cables, the pins are a little longer (deeper) and are designed to straddle (or grab or pinch) the solid copper wire from both sides, in order to make contact with it.
Finally, there are TWO major manufacturers that make these plugs: commonly WE/SS Stewards, or the Tycon Electric AMP styles. Each have their own crimper dyes. TE AMP ones have pins that are a little closer to each other than the Western Electic ones. So if you use the wrong tool, you'll end up buggering up the plug.
Cat 6 must meet more stringent specifications for crosstalk and system noise than Cat 5 and Cat 5e. The cable standard specifies performance of up to 250 MHz, compared to 100 MHz for Cat 5 and Cat 5e.[1]
Whereas Category 6 cable has a reduced maximum length of 55 metres (180 ft) when used for 10GBASE-T, Category 6A cable is characterized to 500 MHz and has improved alien crosstalk characteristics, allowing 10GBASE-T to be run for the same 100-metre (330 ft) maximum distance as previous Ethernet variants.
Cat 6, an unshielded twisted-pair (UTP) design, emerged as an advancement of the UTP Cat 5e and was formalised in 2001. The design of Cat 6 required more stringent precision in manufacturing, which enabled reduced noise and crosstalk, thereby improving performance. The Telecommunications Industry Association (TIA) published Cat 6 in June 2002.[1]
The Cat 6 specification requires conductors to be pure copper. The industry has seen a rise in non-compliant or counterfeit cables, especially of the copper-clad aluminium wire (CCA) variety.[5] This has exposed the manufacturers or installers of such fake cable to legal liabilities.[6] The diameter of the wires in Cat 6 cables ranges from 22 to 26 AWG.[7]
The global cabling standard ISO/IEC 11801 has been extended by the addition of amendment 2. This amendment defines new specifications for Cat 6A components and Class EA permanent links. These new global Cat 6A/Class EA specifications require a new generation of connecting hardware offering far superior performance compared to the existing products that are based on the American TIA standard.[10] The most important point is a performance difference between ISO/IEC and EIA/TIA component specifications for the NEXT transmission parameter. At a frequency of 500 MHz, an ISO/IEC Cat 6A connector performs 3 dB better than a Cat 6A connector that conforms with the EIA/TIA specification (3 dB equals 50% reduction of near-end crosstalk noise signal power; see half-power point).[10]
Confusion therefore arises because of the naming conventions and performance benchmarks laid down by the International ISO/IEC and American TIA/EIA standards, which in turn are different from the regional European standard, EN 50173-1. In general, the ISO standard for Cat 6A is the most stringent, followed by the European standard, and the American one (1 on 1 matching capability).[11][12][failed verification]
