Справочная информация и описание кабеля
Ethernet 10/100/1000Base-T Straight Thru
Wiring scheme: EIA/TIA 568B
This cable will work with 10Base-T, 100Base-TX, 100VG-Anylan and 1000Base-T
and is used to connect a network interface card to a hub or network outlet.
These cables are sometimes called "whips".
Note: While 10BaseT and 100Base-TX only uses two pairs, please do connect
all pairs since 100VG-Anylan and 1000BaseT uses all of them, and save yourself
some future debugging 🙂

Note: It’s important that each pair is kept as a pair. TX+
& TX- must be in the pair, and RX+ & RX- must
together in another pair. (Just as the table above shows).
Just for your information, this is how the pairs are named:

The + side of each pair is called the "tip" and the
— side is called the "ring", a reference to old
telephone connectors.
