Copper cables

Hosts

Computers that WANT to share - client workstations

Media

A way to connect the different parts - cables or air.

Network Devices

A place for them all to connect - switch or router.

Peripherals

Things to share - printer

Services

Data to share - files

Cabling Type

What will carry the data signal?

Speed

How much data can be transmitted per second?

Connector

What is the correct connector type for this media?

Standards

What is the naming scheme for this media?

Distance

How far can a signal travel through a particular type of media before degradation of the signal becomes a concern?

IEEE

Institute of Electrical & Electronics Engineers.

802.3 Ethernet

The primary networking rules that set the standards for how fast data will move and what kind of connections can be made.

802.3u Fast Ethernet

100BaseT (100 Mbps).

Coaxial Cable

A copper core wire that is surrounded by insulators and other shields. Speed: 10 Mbps
• Connector: F-type or BNC
• IEEE: 802.3 Ethernet - 10Base2
• Distance: 185 meters
• Uses: In households to deliver cable
internet and television

RG-6

The most commonly used coaxial cable.

Direct Attach Copper (DAC) Cable

A special type of cable used in data centers for fast connectivity between network backbone devices.
Type: Uses twinaxial cable.
• Speed: 10Gbps to 400 Gbps
• Connector: SF:+ or QSFP+
• Distance: 5 - 15 meters
• Note: Significantly cheaper than fiber optic

Twisted Pair Cable

4 pairs of twisted copper wires in a plastic casing.
Twisting the matching pairs helps reduces signal jumping to neighbor
wires.
• Distance: 100 meters
• Uses: Indoor cabling of LANs.
• Connectors:
• RJ-11 for Category 3 cabling (telephone).
Uses only 3 pairs of wires.
• RJ-45 for Category 5 - 8 cables

Plenum Cable

A type of electrical cable specifically designed for use in areas within buildings used for air circulation. Fire resistant and minima toxic smoke

Cat 3

10 Mbps, 10Base-T Ethernet.

Cat 5

100 Mbps, 100Base-TX Fast Ethernet.

Cat 5e or 6

1 Gbps, 1000Base-T Gigabit Ethernet.

Cat 6a or 7

10 Gbps, 10GBase-T 10 Gigabit Ethernet.

Cat 8

40 Gbps, 40GBase-T [30 meters, alternative to DAC].
