Coaxical
RG Rating
Coaxical cable uses RG rating to distinguish different types of coaxical cables
RG 58
Only Used for Networking in old days.
It has BNC Connectors.
RG 59
They are used for video and networking
RG 6
They are used for video and networking
RG 6 uses F type connectors.This is used for TVs
UTP Unshielded Twisted Pair
Abour 100 meteres, unshielded.
RJ 11
It is used for phone and has 4 contact.
RJ45
It is used for networking and has 8 contacts.
Shielded twisted pair
same like UTP but the wires are shielded for the protection and interferenace like EMI.
Fibre optic cables
it doesnt use electricity, it uses light. It is very fast
Multimode Fiber
It uses LED
Single Mode Fiber
Uses Laser
Plenum rating
As cables are covered in plastic which as ability to burn
PVC (NON PLENMU)
It is very cheap, vulnerable to burn.
Riser Ratin
Desined when you run cables into different floors.
Direct Burial
Direct burial
cables (those meant to be laid under the ground without the use of a protective metal or plastic conduit) are usually constructed with PE jackets, although some have a jacket made from thermoset material which protects well in extremely high temperatures.
