network cable connectors

Hello,
I am trying to make a new network cable with the new connectors I have recently bought from Amazon
http://www.amazon.co.uk/RJ45-Ethernet-Cable-Connectors-Cat5e/dp/B0022AQVKE/ref=sr_1_3?ie=UTF8&s=electronics&qid=1266863772&sr=1-3
The cable I am using is
CAT 5E CABLE UTP SOLID 4 -PAIRS PX94 0710128
I am not sure whether its not the problem with the connectors not being correct as I am not able to push all the pins properly with the crimping tool to fit on the wiring
Please can someone advise how can I go about fixing this?
Thanks
C

I Know I can't read that language dinhchung82 sent to you so this will be more clear:

How to make a Straight Cable
Besides the cable itself and two RJ-45 connectors it is best to have the relevant tools for cutting the sleeving and crimping on the connectors. You will need a sharp stanley knife for trimming the sleeveing and a cable crimping tool to lock the connectors onto each end of the cable.

The cables should have their sleeving trimmed back at each end by approximately 13mm in order to expose the wires for sorting. The wires should then be flattened out and sorted into the following order from left to right; White/Orange, Orange, White/Green, Blue, White/Blue, Green, White/Brown, Brown.
At this point it is best to make sure that the wires are the same length and trim them as necessary. It’s a good idea to check the order of the wires before moving onto the next stage to make sure that orange and brown have not been mixed up as some white wires don’t have their markings coloured clearly. Once the wires are confirmed to be in the correct order then it is time to attach the RJ-45 connectors. This is a simple case of pushing the wires in as far as they will go and then using a crimping tool to secure them into place.
Once one end is done simply repeat the process for the second end, after that be sure to test the cable with an appropriate device before using it in your network. RJ-45 connectors are the most common form of connectors used on UTP Cat5 cables. The RJ simply means Registered Jack and the 45 designation specifies the pin numbering scheme. The cable itself contains 4 twisted pairs of wires making a total of 8 wires.

hello dinhchung
thanks for your input but i dont understand a thing from the URL. i wanted to know if i am using correct connectors, as i am having problem in crimping it with the tool. please can someone advise if the cable and connectors above mentioned are good? if so, why i am unable to make the cable work?
thanks

That crimper should work just fine, Did you buy a cable tester too? They can help you determine which wires are not working. My tip is make sure before you put the wires into the RJ45 cut them at the top to make sure they are all the same length, put them into the jack, then make sure they go all the way to the end, you should be able to tell by looking at both the sides and top of the jack.
 
BTW: The string that is in the cable should have been cut off and should not be in the jack.

Your problem is in your description. The cable you're using is solid-core, vs stranded, and is meant to be used in long, often permanent, cable runs. It is not designed to be used in RJ45 jacks, as the wires are much thicker than stranded cable and will almost always guarantee an unreliable result. To put it another way: you cannot crimp solid core cable. You must use a patch panel or wall jack (which have the same punch down points as the patch panel) and punch the cable down.

I have heard of RJ45 ends that are designed for solid-core cable, but would definitely not recommend it, as RJ45 ends are meant for patch cables that move around a lot and see a lot of wear and tear, and must be stranded for the sake of flexibility. Solid core cables are used for long runs because it has lower signal attenuation and is expected to be bent a few times to get it in place, then punched down and left alone. These days fiber is usually used for long runs and is replacing a lot of solid-core cable.

Realistically, your options are to return the solid core cable or buy a couple of patch panels/wall jacks and a punch-down tool (definitely go learn how to use it properly as there's a technique to making your punchdowns error-free!) and run your solid core between those. For making your own patch cables, you need to pick up some stranded cable. Lastly, on a side-note, Cat6 is complete overkill for Gigabit, so stick with 5E for making your patch cables.

Here's a little blurb if you want to read more:

hi bcbigb
thanks for your input, i have checked all the existing cables which are now connected to differenct PCs on the network and they are all solid-core type and I believe they are connected to RJ45 jacks.
I am not sure why I cannot crimp, perhaps the tool gone broken or something which I am unable to find.
I was able to used old RJ45 connectors to crimp it on the same cable after buying these new sockets I am not able to crimp them I am also not sure whether the problem is with these new connectors?
please advise

Something *could* be wrong with the crimpers...

Do you see any damage inside the opening where you insert the plug, to the small teeth which engage the contacts and push their stabs around the wires?
Squeeze them together partway and compare to the attached.

Though, that doesn't seem likely since those teeth are so much harder than the metal the contacts are made from. Unless a hardened bolt got in the opening or something.

Hey Charlie,

Sorry, I'm not sure I'm being clear. Just to make sure we agree on terminology: "RJ45 Jacks" refers to wall jacks (female-connections) vs "RJ45 connectors"  which are the "ends" on the cables themselves. Crimping is done with a crimping tool that forces the blades in the RJ45 connector through the wires, while on jacks (and punchdown blocks, and patch panels) you need to punch the connectors down.

The 1st problem we need to address: Above you say you have RJ45s being "crimped" on "wall jacks", which is incorrect (hence why I think we need to establish what exactly we're referring to in common terms). At least I've never seen wall jacks that you can crimp, given that it would likely be tremendously poorly designed and cramped in the very least. Punching down is the only way all wall jacks (at least modern ones in the last 10 years) are designed to connect to cables.

The 2nd problem: Beyond this, however, you cannot *crimp* the solid-core cable *at all*, anywhere. Solid core *must* be punched down as a crimper and connectors designed for crimping are not designed to deal with the thicker copper inside of solid-core cables.

What I think you were saying above is that you have RJ45 wall jacks, where you're taking the RJ45 modules out (the things that snap in to the face plate) and trying to connect the cable to those by punching it down.

I'm sorry if I sound like a broken record, but I'm just seeing a problem I've seen time and time again, so I need to be sure we check these facts before moving on or else we're ignoring the solutions right in front of us ;-)

Regards,
~BC

Solid core cable works fine with modular connectors that are designed for both solid and stranded 24AWG wire. Ensure they're not cat6 plugs, which are designed for thicker (23AWG) wire.

Stranded wire will last longer in patch cables that will see a lot of flexing, but if the cable is going to be connected/disconnected maybe a couple dozen times in its life and is not being constantly flexed around, solid core wire will perform just as well as stranded in patch cords, too.

Constant flexing can actually change the annealing of the solid wire, causing it to become brittle and crack/break.  But flexing it occasionally will not harm the wire as much as pulling it tight around sharp corners. Pulling the pairs tight around a corner essentially flattens them all right next to each other, allowing cross talk at that point. With cat5e, anyway...  cat6 has a center core to maintain the spacing between the pairs (but I have never personally bought any cat6 bulk cable yet).

The Cat5e connectors I buy say "for stranded or solid wire" right on the bags... but I've never got any from amazon, either. I guess if their description doesn't *say* they're good for stranded OR solid one should probably presume they are meant only for stranded wire. However, I buy premade stranded patch cords... in lengths of 1, 2 and 5 meters. That's mainly because I buy spools or boxes of only solid 24AWG cat5e wire, usually plenum rated (CMP), but sometimes riser rated (CMR), so I usually don't have the cable available to make flexible patch cords, anyway.

I do not see anywhere the original poster used the term "wall jacks" by the way.
