Hello all

I have just started making my own network cables, is there a way of testing them? Obviously i know plug it in to a computer and a router etc and see if it works, but is there a level of quality that i need to achive speed wise, or is it pretty much it either works or it dont?

Cheers

you can get a cable tester from the local computer supply shop....usually the quickest way to test them....though...as long as the ends match (all the colors are in the same order) then they will work...(and..e.ven then...there are only really 4 pairs of those wires that really get used..so...in theory...you could have one or two pairs wrong...and have it still work)..

As stated, you need a cable tester. From what I hear 'rumors' you can either blow it up make the equipment (unstable), and mess up the CAT5 cable, crossover cable you just made by wiring it incorrectly. Making CAT5 cable,Crossover cables etc... are pretty simple to do. I do sub contracting IT work you would be surprised how many these you actually do make. Crossover cables that is. Best part it's 'A lot cheaper'.

For wiring diagrams (if needed) go here:

Depending on what kind of cable it is, it could show up differently on a cable tester. I made cables for my Cisco networking class and crossovers have 2 pairs taht are switched. I believe our tester was of teh Fluke brand, check sites like:

www.newegg.com

fluke makes a great cable tester...i've used their stuff alot....most modern digital cable testers will tell you if it's a crossover or not...if you've got a loose wire...length of the cable (which is great for finding breaks in a wire...i know this cable is supposed to be 200 feet...on this end it says that it's 100 feet long...and on the other side...it says it's 50 feet long....looks like it's broken at the 100 foot...and 50 foot mark respectively)
