CEDIA ESPA EST Practice Test

Answer - D - TSB 67 is an EIA/TIA standard that specifies the transmission performance standards testing a UTP cable.

Key Takeaway: The TSB-67 concerns itself with only 100-ohm UTP cabling and connecting hardware in the horizontal subsystems of structured cabling systems. As per the parameters of the 568 standard, the new TSB-67 standard assumes that in any configuration, the length of the horizontal UTP wiring does not exceed 90 m and the combined length of the line and patch cords at either end of the link/channel does not exceed 10 m. It defines five specific tests to be performed on the UTP link: wire map, length, attenuation, near end crosstalk, and propagation delay.
