Most of us geeks are too poor to afford an actual cable quality certification tester..
(A Fluke DTX tester costs $12,000 __ that's Twelve-Thousand Dolrruu)
However, There exists a poor man's solution..
You need an Intel ethernet adapter.. (something after year 2010)
And, be running in Gigabit Mode -to- your Router,
Do not Test through to a switch, must test through to wherever you're getting DHCP. Router, ONT, or Cable-Modem
The Proset driver package software has a cable length approximation test..
If it says 0 Meters, and your cable is (greater than)> or (equal)= to 9 meters (the inherent error)..
Then it's definitive that your cable is at least Decent..
Tp4's new ethernet cable is 23awg, STP-vanilla, 31 meters long..
tested result -0- meters.
I found out my old -SSTP cables are ****-tier cables.. pulled all 150 meters of that crap..
The same 31 meters of that sstp cable tested 8 meters.. piece of ****...makes me so mad...
_____________________________________________________________________Copper Cable Basics:Shorter = Better
.. the Longer the run, the more the signal internally refracts causing attenuation..
Thicker is better (for Signal)
.. Lower electrical resistance means lower power loss, less heat, better signal.Thinner is better (for Flexibility)Solid Cables..
are Better than Stranded cables
for Signal..Stranded Cables..
are Better than Solid cables
for Laptops, as stranded cables are Soft and can move.. They are sometimes referred to as tactical cables..
---- For desktop computers (no movement), always use Solid cables if possible.Thickness, Cable Gauge..
The lower the Gauge number, the Thicker the cable..
The gauge number stat on Ethernet cables refers to the thickness of the Conductor..(metal inside twist pairs)
---- Typically, there are 3 options available. 26awg, 24awg, 23awg..
-----------26awg is fine for very short runs, a few feet
-----------24awg is fine for longer runs, less than 100 feet
-----------23awg solid is typically the industry standard and can go the full distance 100s of meters (depending on construction quality of other specs of the cable.)Tightness of Twists..
There are 4 twist pairs in a standard ethernet cable.. @ Gigabit speeds, all 4 pairs are active, @ 100Mbit, only 2 pairs are active.
Each of the 4 pairs has a different twist rate, this helps the network card differentiate and filter out crosstalk.. -Internal crosstalk- is the EM interference of the cable on itself, -External crosstalk- is the EM interference of the cable on OTHER cables.
Some very-very cheaply constructed cables reduce the number of twists per inch
in the cable to save on material (copper).. These will not perform as well as higher twist rate cables..
--Thicker cables meant for longer runs also have a twist rate relative to "all 4" internal pairs, I am not personally sure how this factor influences the signal... I am guessssing, the more tightly twisted 4 pairs would mean they won't move relative to -each other- as much when you bend the cable, therefore preserving a more uniform signal quality.
Copper Clad aluminum (DO NOT BUY, it's Crap.. ) it's made from an aluminum conductor coated with copper. (cheaper to produce)Central Spine:
Inside quality cables meant for longer runs, there is a central plastic spine, this separates the 4 twist pairs, reducing crosstalk = better signal..
---- The central spine is also what influences how much the 4 pairs internally twist relative to each other.. the twist rate of each pairs themselves are independent of the central spine twist.
There is outer Foil Shield SSTP
There is outer Foil Shield + Individual pair inner foil shield STP
There is outer Screen mesh + outer Foil Shield SSTP
There is outer Screen mesh + Foil Shield + individual pair foil shield
The more shields the better.. HOWEVER.. many manufacturers are making Crappy SSTP cables,
they are shielded, but they have a reduced twist rate, and they may not even measure up to U
TP, un-shielded cables.. Connectors..
Cat5 connectors are straight across if you look at the terminated ends
Cat6 connectors are staggered.. up down up down
There are shielded and none shielded connectors..
If you buy a shielded cable, you will need a shielded connector to unlock the shielding ability
If you terminate a shielded cable with a regular non-shielded connector, the Cable will NOT be shielded.. for the Cable to be shielded, the Ground wire of the cable MUST be terminated to a Shielded connector, thereby draining EM interference into the GROUND of the PC..
--- Incidentally, this means your HOUSE also has to be properly Grounded, If not.. then No shields..
Connectors also have an internal hole size
.. MOST connectors
are meant for 24awg cables, they will also fit a 26awg cable, but NOT
a 23 awg cable..
The 23 awg connectors will fit a 24, but it is not recommended
to use a 26awg cable, because 26awg is too thin and may not make proper contact with the terminal pins of 23awg hole connectors.Lastly
Don't be Fooled by Cat5, Cat5e, Cat6, Cat6e, Cat6a, Cat7, Cat7a
... There is no regulation
on the sellers.. they can make any cable, and label them anything they like..
---- The reason the market is so Ghey is because a lower quality cable can still support high speeds, as long as the run is short..
---- So, if you made an Infinitely short cable.. Theoretically, you can label it Cat 9999^9999, and it would be True...
---- If you want the best cable to suit your needs, you MUST get down to the Detail level, and divorce yourself from the consumer obfuscations,
----------For example, they're not suppose to even sell cat7a cables terminated with RJ45, it has to be terminated with GG45, so if you see them selling cat7a terminated with RJ45, it's pure marketing bull****.
---------- Cat-7, Cat-7a aren't actually a recognized standard.. MOST sellers you will find on google are selling cables that won't even properly support the preliminary spec of cat 7a..
