Send us Fan Mail We walk through the cable test results that look “fine” until you understand what the graphs are really saying, from split pairs that still link up to length readings that don’t match reality. Along the way, we share practical ways to spot water intrusion, validate extended distance copper, and avoid patch cord mistakes that can quietly break PoE. • split pairs and transposed pairs causing crosstalk and data loss even with a link light • cable length vs electrical length plus propagation delay and delay skew for gig speeds • why NVP settings matter and how faked settings show up in project-wide test reviews • return loss patterns that point to water in the cable and using HDTDR to locate it • pulling lubricant vs water symptoms and how insertion loss can improve as lube dries • extended distance cabling and selecting vendor-specific test limits in the tester • alien crosstalk testing workflow using saved results, disturbed links, and disturbers • thin patch cords, PoE risk from rising resistance, and using the correct adapters for patch cord tests So make sure you join us for this conversation and let me know in the comments below if you enjoyed this episode and should I do more like this?
