  • Attenuation Standard for Single-Core Dry Optical Cable

    Attenuation Standard for Single-Core Dry Optical Cable

    1 is the cornerstone, offering definitions and test methods for linear and deterministic parameters of single-mode fibers. This document outlines the specifications for a single-mode optical fiber and cable designed for use around the 1310 nm zero-dispersion wavelength, suitable for both the 1310 nm and 1550 nm regions, and compatible with analogue and digital transmission. It details the fiber's geometrical, optical. All three fiber types are characterized as “ low‑water peak ”, meaning the maximum attenuation requirement at 1383 nm is equivalent to the maximum attenuation specified at 1310 nm. This constraint eliminates the concern that the fiber will have high loss in the 1360 nm to 1460 nm band caused by OH. ITU-T and IEC have implemented multiple changes to their respective documents regarding Single Mode Fiber (SMF) since the last IEEE document was published. aThe fiber dispersion values are normative, all other values in the table are informative.
