data communication and networking.types of cables in detail has been discussed.I hope it will be beneficial for bachelors students.

1. Cable types construction Application Transmissioncapacity distanceDD
Up to 500muCoaxial cables  Composedof simple copper
conductorin the middle.
 A plasticlayerprovides
insulationbetweenthe

braidedmetal shield,which
helpstoblockoutside

 It isresistanttosignal
interference due tothe
presence of metal shield.
Twistedpaircables  Consistof twistedpairs,foil
shields,braidedfoilshields
and a jacket.Kindof wiring
inwhichtwo conductorsof
a single circuitare twisted
togetherhence pairof wires
forma circuitthat can
transmitdata.
 Oftenusedfor
telephone
communicationsand
latestEthernet
networks.
 Twistedpaircable and
Coaxial cable are copper
or copper-basedwire
surroundedbyinsulation
withothermaterials.Both
of themcan transmit
television,telephone and
data withelectrical
signals.
Fiberoptics  It’smade of verythin,
pliable tubesof glassor
plastic. Consistsof center
glasscore or plasticfibers,
surrounded byseveral layers
of protective material that
makesthemresistanttothe
effectsof moisture and
lighting.
 These cablesare
consideredidealfor
connectingnetworks
betweenbuildings.
 Transmitslightratherthan
electricsignalshence
eliminatingthe problemof
electrical interference.
26000 times higherin
transmittingsignals than
twisted paircable.
 Fiberopticshasthe ability
to transmitsignalsover
much longerdistances
thencoaxial andtwistedp
fiberopticcable can
deliverthe same typesof
signalswithmuchwider
bandwidth,fasterspeed
and higherfrequencies air
cables.
