Overview

EN 62343-5-1:2015 (identical to IEC 62343-5-1:2014) specifies the test methods for measuring gain tilt settling time of a Dynamic Gain Tilt Equalizer (DGTE). The standard defines how to measure the time required for a DGTE to change its gain tilt from an arbitrary initial value to a desired target value, and it provides terminology, response waveforms and measurement setups for different control types. This second edition supersedes EN 62343-5-1:2009 and introduces a revised title and updated performance parameter names.

Key Topics

• Scope and purpose: Measurement method for DGTE gain tilt settling time (how quickly a DGTE reaches and remains at a target gain tilt).
• Definitions and parameters: Key timing parameters include latency (Tl) or processing time (Tp), rise time (Tr), convergence time (Tc) and settling time (Ts). The standard defines gain tilt settling time as (Tl or Tp) + Tr + Tc.
• Control method categories: Measurement procedures are organized by DGTE control type:
  • Direct control
  • Digital control
  • Analogue control
• Apparatus and measurement setup: Normative guidance on required equipment includes:
  • Light source (e.g., tunable laser source)
  • Pulse generator
  • Optical-to-electrical (O/E) converter
  • Temperature and humidity chamber
  • Oscilloscope
  • Temporary joints (test connectors/splices)
  • Control system and monitoring tools
• Procedure and calculation: Steps for setup, preparation, wavelength selection, application of control pulses/commands/signals, monitoring output and calculating settling times are specified for each control type.
• Informative annexes: Convergence criteria, measurement examples, device-specific notes and temperature-dependency considerations.

Applications and Users

• Who uses it:
  • Optical component and DGTE manufacturers validating dynamic performance
  • Test laboratories performing standardized optical module qualification
  • Telecom equipment vendors and system integrators assessing dynamic equalization behavior in amplifiers and ROADMs
  • Standards and regulatory bodies harmonizing test methods
• Practical value:
  • Ensures repeatable, comparable measurements of gain tilt settling time across suppliers
  • Helps optimize DGTE control algorithms (digital/analogue) and firmware (processing time)
  • Informs system-level design where rapid tilt correction is required (e.g., dynamic gain equalization in DWDM systems)

FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62343-5-1 has been prepared by subcommittee 86C: Fibre optic systems and active devices, of IEC technical committee 86: Fibre optics. This second edition cancels and replaces the first edition published in 2009. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) change in the title b) changes in performance parameter names. SIST EN 62343-5-1:2015
