Do Couplers make connection less stable?

Here is why I ask. I have 3 cables which are all 50ft long. If i connect the 3 cables together with 2 couplers will that make my connection bad or unstable? I couldnt find any 150ft straight through cable at my local stores :(.

shouldn't pose that much of a problem.. you should look into getting cable made for that distance though... most mom&pop computer stores will make cables for you for cheap.. usually about 25cents/foot plus ends, depending on the place.

technically, it will make the cable less stable, but not enough that it would effect your network adversely. you may see a slight dip in speeds, if anything

standard telco RJ-45 couplers do not conform to the Cat5 (or later) spec. In an ideal world, this would cause a problem, however I've used them from here to Tucson and haven't ever had an issue.

There are couplers made that conform to the Cat5 spec, however I've only seen one before and it came with a set of $8000 testers (for that price, it darn well better have!)

If you're just doing a quick'n'dirty network, you should be alright. However, if you start having problem, rule those out first.

the main problem with them is that you are un-twisting the cable.. it untwists before it goes into the RJ45, while it's in the RJ45, then it may/maynot be twisted through the coupler, then through the RJ45 again.. it's untwisted for a long time, considering that you can get data loss from over 1cm untwisted..

any bad EMI in the area will cause problems.. but generally, it should be fine
