Comparing the differences between unshielded and shielded cat5e data cabling

1. Cat5e FTP vs UTP
UTP stands forUnshieldedTwistedPair,while FTPstandsforFoiledTwistedPair.Howeverhow do
we compare Cat5e FTP vs UTP?
UTP cablesdo not have anyshielding.Theyjusthave singleplasticsleeve insulationaroundthe
wires.Howeveronthe otherhand,FTPcableshave a metal shieldaroundall pairstogetherandthen
the outerplasticsleeve insulation.
The Cat5e FTP categorygivesan extrasecurityshield.Therefore the twistedpairsof Cat5e cable
wireshave foil securityaroundthem.Furthermore thisfoil furtherprotectsthe wiresfromEMIand
crosstalk.
Cat5e cables - general outline
Cat5e cablescan transmitdata at the speedof 100 Mbit/s over100 meters.Inadditionthis

Featuresof Cat5e
 Theyformpart of a structuredcablingdesign
 These cablesare ratedfor 100MHz High-SpeedDataApplications
 The cable is capable of GigabitEthernet
 Theyconsistof 4 pairsof colouredcores
 Category5e wiresare consideredascost-effective cables.
 The highestcable lengthis90 or 100 meters.

Where wouldstandard Cat5e cablesbe used
For the majorityof installationsCat5e cableswouldbe specifiedatstandardCat5e cables.
Furthermore these wouldbe specifiedasinall new installationasCPRcompliantcables.
CPR regulationsare there toensure the correctcablesare installedwithregardstofire andsafety.In
additionthisensuresthatthe cablesare safe incase of a fire.Furthermore thisappliestoall cable
categoriesregardlessif theyare Cat5e,Cat6,Cat7 or Cat8. Alsothe same for UTP and FTP.

What do ShieldedCablesDo?
The main advantage of shieldedCat5e andothercablesisthat theyinsulate the innercoresfrom
electrical interference.Inadditiontheyprotectfromall elementsof EMIor electromagnetic
interference.
EMI are electrical interference'sthatare naturallyfoundinthe outside worldandoutsideyour
cablinginstallation.
These interference'scaninclude
 Natural EMI suchas lightning,stormsandnatural electrical charges
 Electrical equipmentinterference
 Omissionsfromelectronicequipment
o Powerlines
o WiFi
o Mobile Phones
o Microwaves
 Generators
 Lighting
 Electrical installations
Shielded cablesalsoincreasethe protectionof noisefromotherdatacablesor evenwithinitsown
cable.Crosstalkisthe disruptionof the signal of the cable fromeitherthe othercoresinside the
same cable or from otherdata cablesinthe installation.External crosstalkisknownasalien
crosstalk.
WhenshouldI use Shieldeddatacables
Followingonfromlistingabove where electrical interference isfoundthese naturallyare areas
where shieldedcanbe consideredasasuitable upgrade toshieldeddatacabling
These are areas where electrical interference andEMIare boundto be high
These buildingsorsituationsmayinclude the following
 Data Centres
 Warehouses(especiallyindustrial)
 Travel centerssuchas train stationsandairports
 Industrial buildingswhere large electrical elementsare found
 DistributionCentres
 Medical Buildings
