Full title and description

St IEC 61300-3-29-2014 — Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-29: Examinations and measurements - Spectral transfer characteristics of DWDM devices. This international standard defines standardized measurement methods and procedures for determining wavelength-dependent spectral transfer functions of dense wavelength-division multiplexing (DWDM) components and deriving key optical parameters such as insertion loss, polarization-dependent loss, isolation, centre wavelength and bandwidth.

Abstract

IEC 61300-3-29:2014 (Edition 2.0) specifies two principal measurement approaches for characterising the spectral transfer function T(λ) (or optical attenuation A(λ)) of DWDM devices. It describes required apparatus, measurement set-ups, reference and device spectra acquisition, calculation methods (including Mueller-matrix considerations where relevant), and reporting details to ensure repeatable, comparable measurements of IL, PDL(λ), channel isolation/crosstalk, centre wavelength, X dB bandwidth, passband ripple and out-of-band attenuation.

Scope

This part of IEC 61300 applies to examinations and measurements of the spectral transfer characteristics of DWDM components and modules. It establishes two measurement methods (Method A: tuneable narrowband light source; Method B: broadband source with tracking filter or tuneable detector), defines the measurement set-up and apparatus, describes system reference procedures and DUT measurement procedures, and gives calculation methods to extract IL, PDL(λ), isolation, centre wavelength and bandwidth-related parameters from measured spectral data. The standard is intended for passive DWDM filter-type components and associated assemblies where wavelength-dependent transmission is a key performance metric.

Key topics and requirements

• Two basic measurement approaches: Method A (tuneable narrowband light source — TNLS) and Method B (broadband source — BBS with tracking filter or tuneable detector).
• Required apparatus and instrumentation: light sources (TNLS, BBS), tracking filter (TF), reference branching device (RBD), wavelength meter (WM), polarizer (PL), polarization controller (PC), detectors (broadband or tuneable), temporary joints and test fixtures.
• System initialization and reference spectrum acquisition procedures to normalise out source and system responses.
• Procedures to measure device transmission T(λ) and calculate derived parameters: insertion loss (IL), polarization dependent loss PDL(λ), isolation/crosstalk, centre wavelength and centre wavelength deviation, X dB bandwidth, passband ripple and out-of-band attenuation.
• Consideration of polarization effects and optional use of Mueller-matrix based corrections where required.
• Specification of test-report content: source/detector types, wavelength calibration, polarization handling, DUT termination, measurement resolution and uncertainty considerations.
• Harmonisation of terms and definitions with related standards (for example IEC 62074-1) and updated device characterization versus earlier editions.

Typical use and users

IEC 61300-3-29:2014 is used by optical component manufacturers, test and calibration laboratories, R&D teams developing DWDM filters and multiplexers, network equipment vendors, and quality/acceptance engineers responsible for characterising wavelength-selective passive components. It is used to produce standardized, repeatable performance data for product datasheets, qualification testing, production verification and supplier acceptance.
