How to connect two short RJ-45 cables to get a long one?

[lawful]

I have two short RJ-45 cables measuring about 25 ft each.
What I need is a 40 ft cable to hook a pc in my room to the
living room internet hub. Is it possible to connect two
25-ft cable or do I have to buy another 40ft long one?

Yes, and a quick google search would have found you one for $2.60.

I'm going to die rather sooner than I'd like. I tried to protect my
neighbours from crime, and became the victim of it. Complications in
hospital following this resulted in a serious illness. I now need a bone
marrow transplant. Many people around the world are waiting for a marrow
transplant, too. Please volunteer to be a marrow donor:

Forget connecting 2 short ones. That just becomes a source of problems. Buy
a 40 or 50 foot one instead. I've seen them on sales for less than 5 bucks.

Yes it is possible, and practical for a one-time use. When you use a
connector, it introduces a new problem source. Best to buy a new
cable--they are inexpensive.

I think a 1-2 line splitter will work. Just use the two sockets
and leave the plug unconnected. I have plenty of them here.

In theory, yes, but, face it, any serious network installation has plug
wall plates (that's a 'cable coupler' right there), multiple
routers/switches, and probably one or more patch panels. Adding a coupler
between two cables at home is peanuts compared to all the connectors in
that arrangement.

No doubt, but why add to the problem unnecessarily?

It may not be an extraordinarily compelling reason but people generally
don't like wasting things, such as existing cables, and a coupler costs
less than a 40 footer.

 

[Papa]

No, that is not true. In most cases the price for either is about the same.
So, as I stated earlier, why add to the problem unnecessarily?

OK, your move. ;>)

Buy a new 40+ft cable instead of connecting them together. This may
actually be cheaper than trying to connect them together with two plugs
and a coupler. A voice-grade coupler is not cheap (as found in Home
Depot), and a data-grade coupler costs even more (see one in
www.lanshack.com).

If you don't like to waste those two 25-ft cables, you can re-use those
two 25-ft cable for other purposes, such as making four patch cables --
no waste. Or you can use the data-grade cables as phone cables, and
use them around the house. A 25-ft phone extension line can come in
handy if you call tech support and he asks you to check something that
is in the next room (like what happened to me when I called tech
support to fix the problem in my broadband router that was behind a
closet).

For the record.. I have had a standard coupler between a 75 ft cable and a
30 foot, OUTSIDE feeding my garage and the juke box for 3 years. not a
single hiccup

IN California, not the worst weather in the world...however it got through
the worst rainy season in 40 years

From under $1.00 to almost $8.00.

I don't know where you get CAT5 couplers but I can buy them all day long
for 2 or 3 bucks.

And if you can get me connectored 40ft cat5 cables for 2 or 3 bucks let me
know where as I'd like to pick up a couple of them. Best I see is 50 ft for
$10.

Not that 7 bucks is going to break the bank.

Hey, thanks. That's even cheaper than the 2 buck jobs.
