I see it on the internet where people strip and untwist their wires more than 10 cm to use with punch-down blocks. Won't this cause cross-talk or can other noises effect the signal when cables are stripped very long? Isn't that bad for the signal?

    Yes, removal of twist must be minimized. And "punch blocks" (66/110?) are something one should never use for ethernet. (if you're talking about the similar type of interface on a patch panel, or keystone, I wouldn't call them a punch block, even 'tho they're similar to a 110 and use the same style tool.)

  • Also, shielded cable must be grounded on each side.
