Looking into Cat8 data cabling and what its performance is capable of. Comparing its transmission and capabilities sin comparison to previous standards such as Cat6 and cat7

1. What is a Cat 8 Cable?
Withthe developmentof fibre,manypeople assumedethernetcableswouldsoonbecome athing
of the past.Somehow,ethernetcableshave managedtostayrelevantinthe worldof technology.
Newdevelopmentsarise everyfew yearsandtheycontinue topushthe envelopeof traditional
coppercables.Sowhat isa Cat8 cable?
The latestdevelopmentisCat8Ethernetcable orcategory8 ethernetcable.Thiscable isan
advancementof itspredecessorCat7.As a general rule,ahighernumberrepresentsnewer
technologythatcan supporthigherdatarates.In addition,otherdifferencescanbe cost,bandwidth,
and shielding.
Difference between Ethernetcategories
Cat5e and Cat6 cables
Cat5e cablesoperate at100MHz and transferdata at speedsof upto 1000Mbps. Cat6 Cables
operate at 250MHz withspeedsof upto 1Gbps. Cat6a cableswill thentake youonto 10 gigabit
speeds
Cat7 Cables
Category7 cablesperformatsuperiorspeedsincomparisontothe previouscables.Cat7 worksat
600Mhz andcan getup to 10Gbps. This is a simplification,and these numbersare basedonspecific
tests.There are variationsoneach cable andsome arrangementsthatcan boostor decrease the
overall performance.
Cat8 Cables
Cat8 cablesare far superior,theysupersedeall previouscategoriesbyalarge margin.The cable
reachesspeedsof 25Gbps (cat8.1) to 40Bbps (cat8.2). Ratedto a frequencyof 2GHz, the cable can
reach an outstanding2billionsignals(transfers) persecond.The highspeedmeansall cableslengths
are upto 30M usinga 2-connectorchannel made upof a highdensityshieldedcable.Incomparison
to Cat5 data transfers,Cat 8 is 250 to400 timesfaster.

2. CablingCost Differences
Much alike mostthings,higherperformancecostsmore.Attimesthis ispurelyaneconomicissue,
but inotherscenarios it’stodo withthe cost of production.Thiscertainlyapplieswhenitcomesto
ethernetcables.Generally,itcomesdowntoshieldingandtwists.Higherfrequenciesrequire more
twistsinthe cable pairsand the processis more expensive.Additionally,itbecomesmore difficultto
shieldhigherfrequenciesfrominterference andcrosstalk.Asyougoup the scale the cost of raw
materialsforshieldingbecomesmore expensive.
Bandwidth explained
The frequencyof a cable determineshow many1sand 0s can be sentacross the cable in a second.
For instance,abasic Cat5 cable sends100 millionsignalsasecond(100Mhz). Cat8 on the otherhand
usesan unprecedented2billion(2GHz) signalspersecond.The cable densityandqualityof shielding
on a Cat8 cable are on a whole differentscale.Thisbecomesobviouswhenyoutake into
considerationthatCat8is ratedfor data transfers250 to 400 timesfasterthanCat5.
