What is the reason for T568A and T568B termination?
2017年1月12日 · There are two types of pinouts for terminating twisted pair cable with a 8P8C (RJ45) connector: But why must one not simply align the wires serially, e.g: Green pair - Orange pair - Blue pair - B...
Any problems mixing T568B Patch cords with T568A Premise wiring?
2015年10月13日 · I chose T568A because: It's specified for residential installations according to ANSI/TIA-570-C for residential structired wiring. I'm also running new phone Cat5e for some phone lines and using T568A there, and I want to be consistent during the installation for simplicity and to be able to repurpose cables if I chose to later.
cabling - Do physical wire properties impact the choice between …
2015年1月23日 · I found claims in a thread that T568A has advantages over T568B due to the fact that each twisted-pair in a cat5/cat6 varies slightly in the tightness of the winding. That would imply that, while nominal, selection of twisted-pairs for TX/RX does have a physical impact.
Connecting two PCs together via External Ethernet cards (T568A or …
My question for the experts is.. The two PCs can only ping successfully when I use a regular Ethernet cable (straight-thru, i believe its known as T568A). I have always thought this PC to PC Ethernet link will require a T568B crossover cable instead. This puzzled me.
