CONCEPT NOTES
Cable is the medium through which information usually moves from one network device to another. 
There are several types of cables which are commonly used with LANs. In some cases, a network will utilize only one type of cable,
while other networks will use a variety of cable types. 

The type of cable chosen for a network is related to the network's topology, protocol, and size. 
Understanding the characteristics of different types of cable and how they relate to other aspects of a network is necessary for the
development of a successful network. 

TOPIC 1: Network Media

The network can be connected through two types of connections: wired  and wireless.

Having a wired connection is more reliable than a wireless connection. However, wireless connections are widely used
by some devices such as cellphones and laptops for their portability.

The following are different wired connections commonly used in networking. However, for this Qualification, we are focusing on UTP
and STP Cables which are most common for Local Area Networks.

1. Unshielded Twisted Pair (UTP) Cable

A popular type of cable that is commonly used for Local Area Networks. It has a two shielded
wires twisted around each other. 

2. Shielded Twisted Pair (STP) Cable

The extra covering of the STP Cable provides extra protection to prevent electromagnetic
interference.

3. Coaxial Cable
This the cable commonly used in television industries. The metal shield surrounding the cable
helps block interference from fluorescence lights, motors, and other computers.

Transmits light rather than electronic signals which reduce the risks of electrical interference. It is ideal for environments where
electrical interference is present.

Wireless Connections
Wireless connections make use of LANs which allow high frequency radio signals to communicate between work stations, servers, or
hubs. 
Wireless networks are ideal for allowing laptops, portable devices, and other devices to connect to the LAN. This is also beneficial in
establishments where it may be harder to install cables.
Wireless Networking
A wireless network is any type of computer network that use wireless data connections for connecting network nodes.

Wireless PAN
Stands for Wireless Personal Area Networks (WPANs). This connection interconnects devices within a small area. An example would
be bluetooth and infrared.

Wireless LAN
Known as WLANs. This is used to connect to local resources and the internet. It links two or more devices over a short distance using a
wireless distribution method - usually through a wireless router/wireless access point for internet access. Wi-Fi falls under WLANs.

Wireless Mesh Networks

This is a wireless network made up of radio nodes organized in a mesh topology. It can be a
(1) Wireless MAN or Wireless Metropolitan Area Network which connects several WLANs.
(2) Wireless WAN or Wireless Wide Area Network which covers large areas such as cities/towns, branch offices, business, public
internet access system, etc.
(3) Global Area Network (GAN) for used for mobile technology such as texting, calling, etc.
(4) Space Network which is used between space crafts within the vicinity of earth. NASA's Space Network makes use of this
technology.

TOPIC 2: Cable Installation

In network installation, we have to be familiar with the RJ45 (Registered Jack).

It is a jack used for Ethernet networking and used for cables. Both T568A and T568B are common wiring standards however the T568B
is widely used in the Philippines.
There are two common network cabling namely the straight-through and the crossover cables.

A straight-through cable is also known as the patch cable or Ethernet cable. This is the most common format for network cables. The
wires have same pins from either end.  This is used when connecting a computer to a modem, router, or switch. This is also used
between networking equipment that are not similar to each other.
A crossover cable crosses the wires from the other end differently to the other. We use these when we connect two devices of the
same type like two computers or two similar networking devices. These wirings use two different ends, T568A and T568B.

However, if we use a device between two devices (such as a switch), all cables are straight through.

TOPIC 3: Patch Panels
A patch panel, also known as patch bay, patch field, or jack field, is used to connect and route circuits for monitoring, interconnecting,
and testing circuits in a convenient and flexible matter.

Having an organized patch panel is important in the workplace. Although the patch panel is meant for organization, it is still essential to
minimize hazards such as hanging and open network cables.

Good patch panel cable management is important. Neat patch, for example, is one of the most common patch panel cable
management systems. 
It allows users to store patch panels in a neat and tidy compartment. It is also compliant with industry standards.
Patch Panel to Modular Box
In connecting a patch panel to a modular box, it is important to take note that the UTP cable at this time is neither a straight-through or
crossover. 
We will be installing both ends on a patch panel and a modular box.

(A) Patch Panel

> First, strip the outer covering of the cable
> Then, arrange the wires according to its proper color coding based on the color
coding you have done on the RJ45.

A – white blue / blue / white green / green / white orange / orange / white brown / brown
B – white blue / blue / white orange / orange / white green / green / white brown / brown
(B) Modular Box
> Strip the outer covering of the cable
> Arrange the wires according to its proper color coding based on the color coding you have done on
the RJ45. Connect the cables ust like the numbers arranged at the figure below.

Performance Task:
Before you get started, make sure you have the necessary tools, and decide whether you're going to use Cat 5e or Cat 6 network
cables.

What you'll need:

 Unshielded twisted pair (UTP) patch cable
 Modular connector (8P8C plug, aka RJ45)
 Crimping tool
 Cable tester (optional, but recommended)

There are four pairs of wires in an Ethernet cable, and an Ethernet connector (8P8C) has eight pin slots. Each pin is
identified by a number, starting from left to right, with the clip facing away from you.
The two standards for wiring Ethernet cables are T568A and T568B. T568B is the most common and is what we'll be using for our
straight Ethernet cable. The tables below show the proper orientation of the colored wires to the pins.

Step 1: Strip the cable jacket about 1.5 inch down from the end.
Step 2: Spread the four pairs of twisted wire apart. For Cat 5e, you can use the pull string to strip the jacket farther down if
you need to, then cut the pull string. Cat 6 cables have a spine that will also need to be cut.
Step 3: Untwist the wire pairs and neatly align them in the T568B orientation. Be sure not to untwist them any farther down
the cable than where the jacket begins; we want to leave as much of the cable twisted as possible.
Step 4: Cut the wires as straight as possible, about 0.5 inch above the end of the jacket.
Step 5: Carefully insert the wires all the way into the modular connector, making sure that each wire passes through the
appropriate guides inside the connector.
Step 6: Push the connector inside the crimping tool and squeeze the crimper all the way down.
Step 7: Repeat steps 1-6 for the other end of the cable.
Step 8: To make sure you've successfully terminated each end of the cable, use a cable tester to test each pin.
That's it. For crossover cables, simply make one end of the cable a T568A and the other end a T568B. Now you can make
Ethernet cables of any length, fix broken connectors, or make yourself a crossover cable. Happy crimping!
