I asked an electrician come and lay cat6 cable in my home with 8 rj45 sockets in my network cabinet and the corresponding 8 scattered around the house, where I indicated.
After a day of work (9-4) he asked me if I can help him understand why netwrork cable tester leds are blinking out of order whereas they are supposed to blink in order. Since I never laid a network or use the tester I said no. He told me that he spent last three hours trying to understand that and he is too tired and that he'd come back another day.
Now this got me interested. Next day I got the cable tester from pbtech and did some testing myself. What I noticed is that he wired the plugs (not sure what for, both ends were supposed to be sockets) not the way it's shown here
his way did not match either A or B. He did them:
- green striped
- orange striped
- blue striped
- brown striped
May be this is some system I have not come across in my internet research, I'm a newbie here, so what do I know.
I also took a socket from the wall and this is what it looked like:
I may be wrong, but this does not look like anything I've seen on images or videos about cat6 keystone punching. To me it looks like all the wires are entangled with each other, which, according to my research could induce a lot of cross-talk, affecting speed.
Now, since I'm not an expert, I'm asking you, guys, does this look okay?
I want to understand a little better when the electrician returns to finish his job what is being done.
Another question, how do they choose if to use T-568A or T-568B?
