which is the apt cable to use between a switch and computers that are above the distance of 40metres?

Question

pls. specify,cos i've used cat5e ethernet cable,but it didn't work,and i also tried cat6,but this time it showed local area connected but it could not connect to the internet

Answer 1

CAT5, CAT5e and CAT6 UTP cable will be fine at 40 metres - the drop off point for CAT5-6 cable is ~ 90 metres ( ~ 295 feet) for 10/100 Fast Ethernet, could be a problem with the cable itself, i.e. badly crimped, interference nearby (if the cable is UTP [unshielded], not STP [shielded]).

You may be better off running another switch at the other end, so that your topology looks like:

[switch]
...
long-haul-40m
...
[switch]
..
short-haul
..
[computers]

Note that a crossover cable will be no good, as that's designed to connect one computer directly to another, not to connect a computer to a switch. It reverses the tx/rx cables on one end to permit switchless operation between two devices, that's all.

Answer 2

i am willing to bet that you are connected to a modem, which does not have sufficient power to send signals over the full distance possible using either cat5 or cat6. get a router or move the modem closer to the switch using a 6 foot patch lead, that should cure the problem

Answer 3

Your Cat5 cable is good for up to 90m, check that all connections are correct and punched down properly, especially in the outlet. Try a cable tester for the pin outs.

Answer 4

Maximum segment length is 100 meters for cat 5, which is well within your range.

I'm betting that your problem is elsewhere. I'd test out the lines to make sure they're wired properly as a basic step.

Answer 5

there are 3 ways to crimp a cable to do different things both ends must be exactly the same and in a certain order for all 3 types of wiring setup.

i use the at&t (cable b) setup and that is what is most commonly sold in stores and installed in big companies

Answer 6

None.

It won't work because even at 10 meters, it'll have too much signal loss.

The max is 12 feet, which is nearly 3 meters, and that is iffy, too.

You need to hardwire for that.

Answer 7

network cables should be ok up to 100mtrs , maybe what you need is a crossover cable which allows data transfer both ways!!!
