@baRu kuTAhu@..ni pasal cabling laaa...

CABLING(UTP/STP--cooper)

1. structured / unstructured

• easy to maintain
• every 5meter radius, must have 1 point/port
• 2 types: standard EIA / TIA 568 A (U.S) 568 B(BRITISH)

why twisted cable??

• to reduce crosstalk n EMT induction
• for better data transmission

baru ku tau pasai apa dlm kabel UTP setiap kaler tu twist tak sama saiz...

• sbb tiap2 kabel ada magnetic field nya sndiri...so kabel tu twist tak sama sbb utk cancellation magnetic field between kabel2 tu..

1. ku tahu gak bila nk wat wiring, cabel data tak bleh parallel dgn cable power more than 3 feets.
2. klu cable data cross dgn cable power, perlu depends pada voltage trsebut.
3. for example, klu kabel power tu 11kV nk cross dgn cable data must more than 2 feets.
