Splicing CAT5e cables 2

We've discussed this before.
If you have the tool available, I'd say a 5 pair 710 module is perfect, that's providing that you have a 5 pair unipress. Otherwise... Terminating to a jack on both ends and using a patch cable between would work as well (providing that the ratings are all the same), or another idea was to use a 110 module stacked to provide a splice (C4 I believe.)
There are many ways to do it.

I think we went through this a bit ago, but here we go again.
Just to clear the air, depending on the layout, this will likely not be standards compliant, but you gotta do what you gotta do.
1. Crimp a modular plug on one wire and put a modular jack on the other wire and plug them together.
2. Crimp a modular plug on both ends and use a Cat5e rated coupler between the two.
3. Terminate the wire on a 110 style or 210 style connector rated for Cat5e.
I'm sure there were other ideas, I would avoid scotchlocks, wire nuts (don't laugh, I've seen it), and other types of splices that are not rated for Cat5e.
Good Luck!
It is only my opinion, based on my experience and education...I am always willing to learn, educate me!

I would be hesitant to make a FAQ out of something that is clearly NOT standards compliant.
I am sure some of you may disagree, but hey...you run your business your way, I will run mine my way, and it doesn't include flagrant standards violations.
I have yet to find a situation that was impossible to get a cable to a workstation, sure some have been more time consuming and expensive than I would like, but it was possible without splicing.
I had a customer once that after explaining the procedure and cost decided to hire someone else that would do the cheap thing, he called me a month later to do it right because he was having frequent problems with the line, something he didn't have with the rest of the system we installed.

Servamatic,
You're obviously welcome to have your opinion, but I strongly disagree -- as we all know.
There are MANY situations where it is IMPOSSIBLE to PRACTICALLY run a new cable for a workstation, ESPECIALLY in situations where it was prewired in a wall with no attic, no subfloor, and not in conduit. I have ran into these MANY times, and I will splice them every single time, and test them with a good tester to ensure their functionality before I sign off on anything.
So rather than be hesitant to make a FAQ, I think it's a great idea. Sure, put a clear marker that it is NOT standards compliant, but it does happen in the business -- and you have to do what you have to do.
Flagrant standards violation? Let's take a look at Webster's dictionary for flagrant:
"conspicuously offensive <flagrant errors>; especially : so obviously inconsistent with what is right or proper as to appear to be a flouting of law or morality <flagrant violations of human rights>"
I would say that your refusal to accept that sometimes this has to be done is flagrant, not an idea to explain people the best way to do something that you don't want to have to do, but have to do, and since there are no "standards" on it, I'd rather lead people in the best direction than flat cross my arms and say the cable has to be reran.
So that's my two cents buddy.

Haha... how about splicing into some existing quad wire? I'm sure that'd work too 
Chiefred,
Like most you are looking for an answer and it obviously isnt on this thread. I feel the answer can be found on the link that skip posted to another thread on this and that skip's response in that link is the best solution for those situations where someone accidentaly cuts your cable (or a rat eats through it) and the customer's budget dictates what they can afford to have done. Also in regards to testing, they did pass test and on another note my software hammers the network pretty hard and I do have a few splices out there that are not causing any issues.

One other solution - put a little workgroup hub at the end of the short cable (terminate it in an RJ-45, or a jack block, your choice), and run another to the final location. If you use the kind with an uplink port, you don't even need to worry about crossover cables. Costs maybe $40 for 10/100, and that's generally less than running another home-run cable to the wiring closet, and it DOES comply with standards. I've had to do it a couple of times!

I have made a few splices to correct someones mistakes with a rj-45 on one end and a rj-45 connector on the other end of the split cable----- as was eluded earlier, it was driven by the customers budget and their acknowledgement that their could be further problems or signal loss. I have never been called back to replace those cables although I have put in new cables or run phone lines and I always ask if they want to pay for a replacement since I am running new cables and the response is always the same---"it is working fine so we will just leave it alone"
Maybe someday they will write a small disclaimer paragraph in the manuals or code that addresses a shortened cable that is respliced and that it just has to be labled as non-code compliant or something. Then I wont feel like I do when I eat the last oreo cookie![[flush3]](/data/assets/smilies/flush3.gif "[flush3] [flush3]")

This is very interesting, check it out:

The zip-tie deformed cable on the right hand side of the picture looks promising...

Speaking of deformed cables - I once had a customer who had continuous network problems - finally started crawling around under his cubicle work area - the person who had pulled the cat 5 to his area had a couple of dozen feet of leftover cable, so rather than cut if off, they wrapped it into a coil, which they looped around the metal (steel) foot of the partition, and snugged it up nice and tight with a cable tie - made an iron-core choke out of cat-5! Once I got rid of that, and re-terminated the cable properly, the problems went away. This was a project where they brought in volunteer help who wanted overtime, rather than trained/experienced cabling techs.

Jack the short cable to an rj 45 (make sure pin out is same as other end) Run new cable to location and jack both ends. Put patch cable between both cables. Will be O.K. as long as your jacking skills are good and the distance isn't to far.Best bet is to run whole new cable.
