IEC 60793-1-44:2011 establishes uniform requirements for measuring the cut-off wavelength of single-mode optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes. This standard gives the methods for measuring the cut-off wavelength of fibre and cable. This edition constitutes a technical revision. The main change with respect to the previous edition is the withdrawal of Annex D. This publication is to be read in conjunction with IEC 60793-1-1:2008.
Abstract
Overview - IEC 60793-1-44:2011 (Cut-off wavelength)
IEC 60793-1-44:2011 defines uniform measurement methods and test procedures for determining the cut-off wavelength of single‑mode optical fibres. Intended for commercial inspection and quality control, the standard specifies how to measure both fibre cut-off and cable cut-off wavelengths using transmitted‑power techniques and reference scans. This edition (2011) is a technical revision and is to be read in conjunction with IEC 60793-1-1:2008.
Key topics and technical requirements
- Scope and purpose: Establishes repeatable procedures to quantify the wavelength at which higher‑order modes are sufficiently suppressed in single‑mode optical fibre.
- Definitions: Measured cut‑off wavelength is the wavelength above which the ratio of total power to fundamental‑mode power has decreased to
