Category 3 Ethernet Cable - Cat3

Unshielded twisted pair (UTP)

10 megabits per second (Mbps) Used in 1990s

 

Category 5 Ethernet Cable - Cat5

Cat 5 cables introduced the 10/100Mbps

which means that the cables can support either 10 Mbps or 100 Mbps

 

A 100 Mbps speed is also known as Fast

Ethernet.

 

Category 5e Ethernet Cable - Cat5e

The Category 5 e standard is an enhanced version of Cat 5 ,which is optimized to reduce crosstalk, or the unwanted transmission of signals between data channels.

Speeds support 10/100 Mbps and 1000 Mbps (Gigabit). While both Cat 5 and Cat 5e cables contain four twisted pairs of wires, Cat 5 only utilizes two of these pairs for Fast Ethernet, while Cat 5e uses all four, enabling Gigabit Ethernet speeds. Cat 5e cables are backward compatible with Cat 5 cables.

 

Category 6 Ethernet Cable - Cat6

While Cat 5e cables can handle Gigabit Ethernet speeds, Cat 6 cables are certified to handle Gigabit Ethernet with a bandwidth of up to 250 MHz. Cat 6 cables have better insulation and thinner wires, that provide a higher signal-to-noise ratio. Some Cat 6 cables are available in shielded twisted pair (STP) forms or UTP forms. Cat 6 cable is also backwards compatible with Cat 5 and 5e cables.

 

Category 6e Ethernet Cable - Cat6e

Improves upon the basic Cat 6 cable by allowing 10,000 Mbps data transmission rates and effectively doubling the maximum bandwidth to 500 MHz. Category 6a cables are usually available in STP (shielded twisted pair)  form, and, as a result, must have specialized connectors that ground the cable.

 

Category 7 Ethernet Cable - Cat7

Also known as Class F, is a fully shielded cable that supports speeds of up to 10 Gbps (10,000 Mbps) and bandwidths of up to 600 Mhz. Cat 7 cables consist of a screened, shielded twisted pair (SSTP) of wires. Because of this shielding, they are thicker, more bulky, and more difficult to bend. Each of the shielding layers must be grounded
