Cat6 Patch Cord

The standard connection method of Cat6 network cable follows the TIA/EIA 568 cabling standard, which is consistent with that of CAT5E network cable. The core lines are T568A and T568B, among which T568B is currently the most commonly used connection method in commercial and civilian scenarios.
I. Two standard wire sequences (RJ45 connector connection methods)
When wiring, please note: The crystal head clip should face down and the metal contacts should face yourself. From left to right, they are pins 1 to 8, and the wire sequence corresponds as follows:
Pin numbers 1, 2, 3, 4, 5, 6, 7, 8
T568B (Commonly used) Orange white Orange Green White Blue Blue White Green Brown White Brown
T568A green, white, orange, white, blue, blue, white, orange, brown, white, brown
Ii. Two Types of connection Methods and Applicable Scenarios
Direct connection method (the most commonly used)
Operation: Both ends of the network cable should be in T568B sequence, or both ends should be in T568A sequence.
Applicable scenarios: The vast majority of daily networking, such as the connection between computers and switches/routers, the connection between surveillance cameras and NVRS, the connection between wireless aps and switches, etc.
Cross connection method (rarely used
Operation: Use T568A sequence at one end of the network cable and T568B sequence at the other end.
Applicable scenarios: Direct connection of the same devices without automatic negotiation function in the early days, such as direct file transfer between computers and cascading between switches.
Note: Nowadays, most network devices support MDI-X automatic negotiation, and the application scenarios of cross-cables have become very rare.
Iii. Key Precautions for Wiring Category 6 Network Cables
Category 6 network cables, due to their thicker diameter and denser twist pitch, require the use of dedicated Category 6 RJ45 connectors (with built-in separators that can fix the positions of four pairs of twisted wires and reduce crosstalk). Category 5 connectors cannot be mixed.
It is recommended to control the stripping length within 1.5 to 2cm. If it is too long, it will damage the twist pitch of the network cable, resulting in a decline in transmission performance. When arranging the wires, do not forcibly straighten the stranded wires; keep an appropriate twist pitch.
When pressing the wires, make sure that each wire core is fully pressed against the top of the crystal head. The metal contacts should Pierce through the insulation layer of the wire core. After pressing with the wire crimping pliers, cut off the excess wire core.
If it is used to shield Category 6 network cables (STP/SFTP), the shielding layer of the network cable needs to be connected to the shielding shell of the crystal head to enhance the anti-interference ability.
