Never use cca cat5e again! Changed some cca for high quality 100% copper

[tech_junkie]

CCA often printed on the box the cable came with ..
CCA can be printed on the cable itself ..

you can cut a small section off and try to scrap the coper wire and see if it is solid copper or not.

also you can check resistance .. CCA higher resistance

some also use a fire test .. CCA burns differently than copper ..

The other big mistake a DIY installer would make is using plenum cable outside air vents, floor to floor as this cable is allowed to burn. Plenum shouldn't be ran anywhere except where it shares a ventilation duct/airway. Riser cable is self extinguishing inches from where it catches on fire and designed to do that to prevent the fire from spreading. where plenum is allowed to burn for 12 feet and is not self extinguishing.

one channel is half- duplex while another channel is full duplex.
It might be normal if other tcp traffic is going down the wire.

UDP tests is what you need to test, and iperf2 is more accurate for UDP measurements.

noob using iperf - a learning curve

just tried a couple of udp test with iperf2

FYI

 

[tech_junkie]

So its a good 100M cable TCP/UDP but not a good 1GB cable for real time UDP transmissions, but ok for TCP because its asynchronous and retrying packets are not going to be noticeable.

Basically, you get what you pay for in a $80 1000ft roll they sell for $120+

Do I need to run something like this?
iperf2 -c 192.168.1.206 -u -e -i 1 --isochronous=60:1000m,100m --realtime ?
Changing the 100m parameter to 1000m?

Or do you mean the cca is not handling the giga connection well?

so worth upgrading to premium 100% copper cables? Is it the cca limiting the transmission from the data you looked at?

What I might do tonight is run a length of the new copper cable between the floors down the stairs externally and retest bypassing the cca
Only got today left with the 66 mts I have as someone else is taking it tomorrow for an installation.

Yes, and What does it output.

Yes, and What does it output.

Reached 10 secs and then:
Warning: did not receive ack of last datagram after 10 tries

after work I will hook up the copper cable and retest

Maybe if it is noticeable, but I wouldn't use that wire in the infrastructure, just patches to equipment.

1000m, 100m is used for a 10Gb line (100M payloads)
what does:
iperf2 -c 192.168.1.206 -u -e -i 1 --isochronous=60:1000m,10m --realtime
output (10MB payloads @ 1Gb)?

hmm same result, even with the laptop connected directly to the router

I'll try the same test from various points in the house

 

[tech_junkie]

Its acceptable, because the errors are recovering in the buffers (greater than 1ns but less than 100ns) ideally, all should return at .001ms or 1ns. This can even happen in copper if the wires are twisted around at the crimps or a twist or pinch in the wire.

I'll try the test with the direct coppert cable later if I get time and compare

I may well put a new copper cable in between the isp bridge and my asus gateway. Really not sure if that one is copper or not. Peace of mind for the cable that carries the most traffic between the fibre bridge and gateway

 

[Pentagano]

Results from downstairs switch (40m cat6 cca direct to gatweway inside wall).

Better than the previous result by the looks of it. So maybe due to the cat6 as opposed to the cat5e. Looks fairly acceptable for cca if I'm not wrong.

Much better 0% loss on my AMD pc now BUT the connection seems to be capped at 100mps - even though I select full duplex 1GB in NIC settings,

How can I fix this? windows 10. Reset network settings perhaps?
UPDATE: bad cable/connectors causing the 100mps cap - Used those pass through RJ45's and sometimes if they don't fit flush they don't work properly

Needed a couple of cheap small 4 port switches. Never believed the tenda ones sg105 would deliver Giga for each port. Son happy with his ps4 and laptop (600/60). Kitchen network happy with the 2 exterior cams connected, 5ghz mesh unit and 1 ddwrt access point. No issues.
