Key Features
Validator™
Ethernet Speed Certifier
• Conducts Bit Error Rate (BER) testing to speed certify
Ethernet data transmission speed up to 1000BASE-T (1 Gb/s)
• Measures Signal-to-Noise Ratio and Skew to uncover
impairments to Ethernet data transmission
• Tests for opens, shorts, split pairs, miswires, and reversals and
measures distance to opens and shorts—supports all network,
telco, and coax cables
• Includes Plan-Um® software to create network layout;
document cable tests; show network topology; and record
moves, adds, and changes
The Validator™ offers a complete solution to test and speed certify the data-carrying
capabilities of Ethernet network cables up to 1 Gb/s by testing for noise in the net-
work, detecting faults in the cabling wiring, and ensuring that cables are able to
support the speed capabilities of active equipment. The Validator can be used as a
cost-effective alternative to full TIA/ISO cable certification in environments where
ensuring cable runs support Ethernet speeds up to Gigabit Ethernet is adequate.
To certify Ethernet speed performance of cable runs, the Validator conducts Bit
To certify Ethernet speed performance of cable runs, the Validator conducts Bit
Error Rate (BER) tests by sending data packets down specified cable runs at defined
data rates to check for errors at the maximum throughput of the link. The Validator
also reports on signal quality that can impact high-speed data transmission by
measuring signal-to-noise ratio (SNR). Skew measurements report on the signal
time delay between pairs that can impact Ethernet data transmission. Finally, the
Validator provides continuity testing that detects opens, shorts, miswires, split
pairs, reversals, and high-resistance faults while accurately measuring distance to
faults and total cable length.
