HI,

I´ve a female  rj45 5e connector, see the attached photosPhoto1Photo2.. is good crimped.

The problem is when I try to crimp that wire, male connector to the switch using T568B mode. Using a Fluke  micromapper wire tester, the leds show a problem with pair 4-5.

What´s wrong? I think I´m wrong using T568B at male connector.

Any idea?

Regards

The crimper I have is for Male Connectors. Cat 5E and Cat 5 are the same.

I do not have a crimper for Female connectors (these are normally punch down blocks). Do you have the correct crimper? Did you lay out the pairs correctly?

4-5 is the blue pair. Check if the wires are not pinched and that you used the correct order.

What is the problem with 4-5?   The difference between 568a and 568b only swaps the wires on 1,2,3 and 6 and doesn't affect 4&5.  Pin 4 should be solid blue and 5 should be blue/white (blue with white stripe or white with blue stripe or just the white wire that is wrapped with the blue wire).

Try to keep the twist as tight as possible for as long as possible in the connector to keep cross talk down across the pairs.

I can see from the photo that the blue and blue/white pair are in the correct positions. The socket looks quite old. Reusing old sockets can be problematic - they aren't designed to be re-terminated multiple times. I'd suggest you spend a couple of dollars and purchase a new socket.
You also need to make sure the socket type matches the cable type. Most sockets are designed for solid wire, not stranded. Make sure you use a Cat5 socket with Cat5 cacble and a Cat6 socket with Cat6 cable. Mixing Cat5 with Cat6 will cause problems.
Does the socket require a punch down tool? Make sure you use the correct tool. e.g. If the socket needs a Krone tool then make sure you use a Krone compatible punch down tool.

 One of the main issues with network wires is that you never have enough.  You run plenty and plan for the worst case but you still end up needing more.  What many people do not realize is with 10BaseT and 100BaseT (but not 1000BaseT) networks you …
