BS IEC 61935 is a series on specifications for the testing of balanced and coaxial information technology cabling. Coaxial cable is a type of transmission line, used to carry a high-frequency electrical signal with low losses. BS IEC 61935‑1‑1 specifies additional reference measurement procedures for level V field testers, transverse conversion loss (TCL) and equal level transverse conversion transfer loss (ELTCTL). The requirements for field tester accuracy to measure these parameters according to the requirements of ISO/IEC 11801-1 are specified in BS IEC 61935‑1‑1.
BS IEC 61935‑1‑1 on coaxial cable is useful for:
Coaxial cable or coax is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket. BS IEC 61935‑1‑1 specifies additional reference measurement procedures for level V field test transverse conversion loss (TCL) and equal level transverse conversions transfer loss (ELTCTL) and the requirements for field tester accuracy to measure these parameters. Measurement of TCL and ELTCTL is not required by IEC 61935-1; however, these parameters are specified requirements of unscreened cabling for class D up to FA according to ISO/IEC 11801-1.
BS IEC 61935‑1‑1 describes the practice of such testing and provides a reference level of accuracy for such field testers. In addition, those wishing to use field test instrumentation for the laboratory evaluation of systems or components according to ISO/IEC 11801-1 could also use BS IEC 61935‑1‑1 to ensure a consistent level of understood accuracy. Using BS IEC 61935‑1‑1 you can specify additional reference measurement procedures for level V field testers, transverse conversion loss (TCL) and equal level transverse conversion transfer loss (ELTCTL).
