Direct cable and cross line
The positive line, that is, straight line, standard 568b): Two-end line sequence, from left to right sequences: white orange, orange, white green, blue, white blue, green, white brown, brown. Anti-line, ie intersection, (568a): one end is the line sequence of the positive line, the other end is from left to right: white green, green, white orange, blue, white blue, orange, white brown, brown. The following is the correct choice of the normal line and the opposite line in the connection of various devices. Among them, Hub represents hub, SWITCH representative switch, Router representative router: PC-PC: Anti-line PC-HUB: Positive line HUB-HUB ordinary port: anti-line HUB-HUB-level connection-level connectivity: anti-line HUB-HUB ordinary Port - Level Connection: Positive Line HUB-SWITCH: Anti-line HUB (Level 1) - Switch: Positive Line Switch-Switch: Anti-line Switch-Router: Positive Ring Router-Router: Anti-line 100BaseT connection twisted pair, 100MB / s EIA / TIA 568B as standard specifications. The production steps are as follows: Step 1: Using the twisted pair length required by the oblique clutch, at least 0.6 meters, up to 100 meters. Then use the twisted palains (actually useless shears) to remove the outer skin of the twisted pair to 2-3 cm. There are some twisted pair cables contain a soft nylon rope. If you are stripping the outer skin of the twisted pair, I feel that the bare part is too short, and when it is not conducive to the production of RJ-45 connections, I can grasp the twisted pair. The outer skin, then pinch the nylon wire to the bottom of the outer skin, you can get a long bare line. (As shown)
Step 2: The twisted pair cable after the stripping is completed, as shown on the right. Step 3: Next, the dial operation is to be performed. The orange pair of bare twisted pairs is bullive in front of their own, and the brown line is bullive in its own direction, and the green pair of green pair is stripped to the left, and the blue line is stripped right, as shown. On: Orange Left: Green Next: Brown Right: Blue
Step 4: Place the green pair of lines with blue to the blue position, while orange pairs and brown pairs of wires are not moving, that is, placed outside, as shown.
