RJ-45 connector

An Ethernet twisted pair cable connects network devices through the RJ-45 connectors at the two

ends. Figure 41 sh

ows the pinouts of an RJ-45 connector.

Cable pinouts

EIA/TIA cabling specifications define two standards: 568A and 568B for cable pinouts.

• Standard 568A—pin 1: white/green stripe, pin 2: green solid, pin 3: white/orange stripe, pin 4:

blue solid, pin 5: white/blue stripe, pin 6: orange solid, pin 7: white/brown stripe, pin 8: brown

solid.

• Standard 568B—pin 1: white/orange stripe, pin 2: orange solid, pin 3: white/green stripe, pin 4:

blue solid, pin 5: white/blue stripe, pin 6: green solid, pin 7: white/brown stripe, pin 8: brown

solid.

Cable type

Based on performance

Ethernet cables can be classified into category 3, category 4, category 5, category 5e, category 6,

category 6A, and category 7 cable based on performance.

Table 49 Ethernet cable description

e Descri

tion

Category 5 Transmits data at a maximum speed of 100 Mbps, with a bandwidth of 100 MHz.

Category 5e Transmits data at a maximum speed of 1000 Mbps, with a bandwidth of 100 MHz.

Category 6 Transmits data at a speed higher than 1 Gbps, with a bandwidth of 250 MHz.

Category 6A Transmits data at a speed higher than 10 Gbps, with a bandwidth of 500 MHz.

Category 7 Transmits data at a speed higher than 10 Gbps, with a bandwidth of 600 MHz.

NOTE:

The 10 Gbps RJ-45 Ethernet ports use category 6A or category 7 Ethernet twisted pair cables for

connection. Other RJ-45 Ethernet ports use category 5 or higher Ethernet twisted pair cables for

connection.
