And i thought this one was expensive lol

That is stranded cable, you should be installing solid core cable for fixed wiring.
Solid core cable is generally accepted to be more stable that stranded cable for data transmission, stranded was designed primarily for patch cables due to its flexibility. However people are now coming round to the idea that solid core is acceptable for patch cables too.
Secondly, stranded cable is more susceptible to degradation through moisture ingress and I would not want to run long lenghts of cable with the risk of this.
The twisted pair lays better if multi stranded as well
I do not agree with this at all, data cabling is my day job and I find solid core cable far easier to work with.
Surely the percieved prob of mains radiated interference is knocked on the head by the twisted pairs they go CW & ACW.( maxwells laws apply here ), shielded pairs anyway ,.
The twisted pairs are there for cancellation effects from neighbouring pairs, not strong electrical inteference.
I have found it not to be much of a problem when laying computer room cables .
I have just finished a recable of 205 network points, the school was getting throughput as low as 1Mbps from some points back to patch panel. The previous cable had been pulled in by a building company, they had pulled it straight over the top of mains cables and flourecent lighting.
What do you use to check for Crosstalk, Echo, Jitter etc?
not all installations have the luxury of nice cable tray s and space.
Very true, but there are better ways of doing things
I have only found extreme vigilence needed laying cables in some very expensive / high security , test lab establishments then you have to follow a dedicated wiring plan that has been designed especially for each cable run .
We always create a dedicated wiring plan for every job, I cannot understand how you could work otherwise?
