Balance measurements help ensure networks will properly operate. 1000BASE-T and 10GBASE-T may malfunction, even when all other transmission parameters provide good margins above the standard limits. The balance of the two conductors in a twisted pair is what cancels out noise injected into the cable. Balance is also responsible for preventing signal leakage from the cable. As we move to higher frequencies and faster data rates, cables are even more sensitive to noise, and ensuring good balance becomes more vital than ever. Passing balance measurements also ensure the network will deliver the PoE you need.
