I would hope someone who did datacenter cabling would be able to explain that the color coding system has a meaning to humans and not to the electronics in a calm and coherent manner to an honest inquiry.
Additionally, labels on datacenter cabling tends to be less cryptic like "DCX-IN-FQP_9".
Maybe. But if a smartass comes in to where I work and tells me how wrong I am based on their shallow understanding of the domain I am likely to become frustrated.
Jesperwe said they confronted this salesperson about the cables. They then lectured the salesperson on theory. There’s no indication a question was asked with an honest desire for the answer.
When a conversation becomes a confrontation nuance is the first casualty. Jesperwe and the salesperson may have been participating in completely different conversations from their perspectives. Without more information I can’t draw a further conclusion beyond jesperwe participating in (or instigating!) a confrontation with a retail salesperson.
I had hoped that my last sentence made it clear that this was all meant to be the same kind of engagement with the ridiculous premise that occurred in the linked article, but you seemed to take it earnestly.
You might get the same response in a data center if you say “the color doesn’t matter because the cables are all reciprocal.”
