What is BS EN IEC 62614 ‑ 1 about?
BS EN IEC 62614 is a series on fibre optics. BS EN IEC 62614 ‑ 1 describes the launch condition requirements used for measuring multimode attenuation in passive components and in installed cable plants. In BS EN IEC 62614 ‑ 1 , the fibre types that are addressed include category A1-OMx, where x = 2, 3, 4 and 5 (50 μm/125 μm), and A1-OM1 (62,5 μm/125 μm) multimode fibres. BS EN IEC 62614 ‑ 1 can be suitable for multimode attenuation measurements for other multimode categories and/or other wavelengths. BS EN IEC 62614 ‑ 1 describes launch condition requirements for optical attenuation using sources with a controlled encircled flux (EF).
