The JDSU NT950 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 network, 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 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. Specifications. Test Connectors: 8-position shielded modular jack (data), 6-position modular jack (telephone), F-coax (video) and dual banana jack (security, speaker, etc.). Cable Length: maximum cable length for testing for split pairs is up to 457.2 m (1,500 ft), depending upon cable type.
