Copper Cabling In an Internal Environment (3667-02: Unit 104)

This was a 3 day course.

Day 1 and 2 are theory until the 2nd half of day 2 where I did the practical. 3rd day I did more practical and mock test to real exam.

The Theory Section:
I learn more deeper into Health and Safety and more of electrical theory such as AC (Alternate Current) and DC (Direct Current). Also just like the 101 course about the Earthing (Ground). Then I learn about the Ohms law and how the voltage works. The part is I learn about the Ethernet Cable, understanding about Cat 5 to Cat 7/8 and the attenuation. Discussing about the Network Topology and how it works and understand more about the network tools we use to do the cabling.

The Practical Section:
This is my favourite part as I am more of a hands-on/practical person.
I had this student came to this course to renew his card or license and he was very experienced.
I did few videos on my YouTube and some post on Facebook with pictures showing me doing wiring on patch panel and wall socket.
I look at most of the videos and they use the normal cable cutter however he show me a different tool that way I can be due diligent on cutting the cable. He show me this unusual tool. This tool has a nob which can adjust the blade height (picture) that way you can cut the skin of the ethernet cable carefully.


He explain to to cut it more professionally and pull the skin off carefully before you get to the 4 pair twisted copper.
I finally manage to create a Ethernet cable as I use to struggle on how to create a cable, but thanks to him I manage and successfully create a Cat6 Cable.
I also done a Patch panel lesson and terminating cable which I am very good at because I done few videos on it.
What I have been told that I got to use the B side wiring not the A side. A side is T568A and B side is T568B. T568A standard is the American version and T568B standard is the British version. Since I live in the UK, then I use the T568B Standard.
The next day I had to create a faulty wiring to purposely show an error results by using a Network Cabling Auditor tool called Ideal Lantek 3.
Ideal Lantek 3 is a Cable Certification tool is to audit cable wiring if the cables are terminated successfully. This is a powerful this is use for auditing and to make sure the wiring is to meet the 'Certified Network Standards' which each cable test has to 'pass' before using the patching into live environment. I enjoy using the tool however the tool is very expensive to purchase.
I really enjoy the practical as this will help me at my workplace.

Test and Exams:
I did few mock test  and practice test before the real one. Which I learn from.
Then I did the real exam. Some were tricky. However I manage to pass which I am happy with the results.

Basic Principles of Communications Systems (3667-02: Unit 101)

I finally doing the City & Guilds Course to learn about the Data Cabling, however this one is an essential core course. I am not going to mention the company name unless they want me to, however they are very excellent Training providers.

The last time I done City & Guilds was over 20 years ago when I was doing my NVQs.
It was boring as this is all theory but it is a core subject and boring are the essentials unfortunately if anyone reading this:

I learn new things such as:

- The PUWER rules (Provision and Use of Work Equipment Regulations 1998). This is where the user is responsible for the work tools and equipment. Using the correct tools which is intended to do for the task. 

-Using the correct voltage between 110v vs 240v. Recommend 110v tools.
Ladder 4 to 1 rules. 4 meters per 1 meter wide. Basically when you use the ladder, it is about how to use it correctly or else you fall.

- Asbestos - When you go to sites to do cabling, you have to learn about asbestos as you be going across ceilings and walls, mostly ceilings to wiring as you be feeding the cables between the ceiling and walls.

- Classes of Laser, there are 7 classes of lasers from low to high. High laser class is more dangerous than the other.

- I learn about the Health and Safety, identify the safe practices, learn about the SI Units and symbols and principles of data communication.

- Ohms law

- Wavelength

- Types of cabling we use such as coaxial to ethernet. Also mention about Fibre Optic.

I done the exam and I failed by 1 question which is unlucky for me as it was close.

Update on 8th April:
I did a retake of the exam which I failed at the time and manage to pass with flying colours. What a comeback. I finally pass both exams which I am now relieved.
