Technical Systems Bulletin 95 (TSB 95), "Additional Transmission Performance Guidelines for 100 W 4-Pair Category 5 Cabling," was developed solely to verify performance levels of an installed CAT 5 cable plant for additional parameters of equal level far-end crosstalk (FEXT), power sum equal level far-end crosstalk (PSELFEXT), and power sum near-end crosstalk (PSNEXT) required to support existing two-pair and four-pair applications like Gigabit Ethernet.
Category 5 Cable Tests Transmission Parameter Channel Performance NEXT @ 100 MHz 27.1 dB PSNEXT @ 100 MHz NA Attenuation @ 100 MHz 24.0 dB ELFEXT @ 100 MHz 17.0 dB(*) PSELFEXT @ 100 MHz 14.4 dB(*) Return Loss @ 100 MHz 8.0 dB(*) Propagation Delay @ 10 MHz 555 ns Delay Skew 50 ns
Measurements include Wiremap, Propagation Delay, Delay Skew, Length, Attenuation, NEXT, PSNEXT, ACR, PSACR, ELFEXT, PSELFEXT, Return Loss, and Resistance.
