Connector anatomy

RJ45 (8P8C)

01 8 gold contacts The eight blades pierce the wire insulation to touch the copper directly — four pairs, two for transmit and two for receive.
02 Locking clip Snaps inside the socket so vibration cannot pull the plug out. A snapped clip is the number-one cause of intermittent network drops.
03 T568A vs T568B Two equivalent wiring standards: T568A puts the green pair on pins 1-2 and orange on 3-6; T568B swaps them. Performance is identical as long as both ends of the same cable use the same standard.
04 Strain-relief boot Stops the wires flexing where they leave the plug — the exact point most cables fail.
05 Outer jacket The outer sheath protecting the conductors inside from abrasion and moisture.

How it works

Cable construction

Four pairs, each twisted at a different rate from its neighbour. The twisting makes both wires of a pair pick up identical noise, which then cancels when the far end subtracts them. That alone is why networking works over a hundred metres.

This cable is shielded: a grounded conductive layer around the pairs, which earns its place near mains cable or motors.

From the published standard

How it works

Four copper pairs, each twisted at a different rate from its neighbour. The twisting makes both wires of a pair pick up identical noise, which then cancels when the far end subtracts them — that alone is why networking works over a hundred metres. The 100 metre figure in TIA-568 is a limit on the whole channel, meaning the permanent run plus the short patch leads at each end, not on the cable alone.

Pairs: 4 twisted pairs, 100 ohm ±15% characteristic impedance
Channel limit: 100 m total, including patch leads at both ends
Governing standard: ANSI/TIA-568
