Abstract
What is BS IEC 61935 ‑ 1 ‑ 2 - Specification for the testing of balanced and coaxial information technology cabling about?
BS IEC 61935 is a series on the specification for the testing of balanced and coaxial information technology cabling. A balanced and coaxial cable utilizes that extra signal wire that carries a copy of the signal, but the two copies are sent with their polarity reversed. BS IEC 61935 ‑ 1 ‑ 2 specifies additional reference measurement procedures for the measurement of resistance unbalance with field test instrumentation, and the requirements for field tester accuracy to measure resistance unbalance according to the requirements of ISO/IEC 11801-1 . BS IEC 61935 ‑ 1 ‑ 2 specifies reference measurement procedure for resistance unbalance within a pair, between pairs, its parameters and the measurements.
