Overview

EN 61290-5-1:2006 (IEC 61290-5-1:2006) defines a standardized optical spectrum analyzer (OSA) method for measuring reflectance parameters of optical amplifiers. The standard applies to all commercially available optical amplifiers (OAs) and optically amplified sub-systems - including optically pumped fibre amplifiers (OFAs), semiconductor optical amplifiers (SOAs) and planar waveguide OAs (POWAs). Its objective is to establish uniform requirements for accurate, repeatable measurement of maximum input reflectance, minimum input reflectance, and output reflectance using an OSA-based test setup.

Key topics and technical requirements

• Scope and exclusions
  • Applies to OFAs (rare‑earth doped and Raman), SOAs and POWAs.
  • Does not apply to distributed fibre Raman amplifiers (evaluation under consideration).
• Measured parameters
  • Maximum input reflectance, minimum input reflectance, and output reflectance as defined in IEC 61291‑1.
• Required test apparatus and performance
  • Optical source: fixed or tunable; sufficient power to resolve reflectance down to around –50 to –60 dB; side‑mode suppression > 30 dB; integrated/connected isolator (> 40 dB).
  • Optical spectrum analyzer (OSA): spectral resolution ≤ 0.1 nm; linearity and spectral‑power accuracy within about ±1,5 dB and ±1 dB; polarization dependence ≤ ±0.1 dB; high dynamic range.
  • Optical coupler (3 dB, 2×2): insertion loss < 3.5 dB; directivity ≥ 60 dB; connector reflectance < –60 dB.
  • Optical power meter, isolator, variable optical attenuator: specified accuracy, isolation and reflectance limits to ensure measurement integrity.
  • Polarization‑dependent loss of passive components and tolerances are constrained (e.g., PDL variation better than 0.2 dB).
• Procedure and calculations
  • Standard includes detailed setups (figures for input reflectance, insertion loss, OA input power), measurement procedures and calculation methods for reporting reflectance results.

Applications and users

• Ensures consistent production test, type‑approval, R&D characterization, and quality assurance of optical amplifiers and amplified subsystems.
• Primary users: manufacturers, component/test labs, systems integrators, telecommunications equipment vendors, and regulatory or standards compliance engineers.
• Practical benefits: comparable reflectance data across vendors, better control of back‑reflections in amplified links, and improved system design for DWDM and long‑haul networks.

Related standards

• Normative reference: IEC 61291‑1 (optical fibre amplifiers – generic specification).
• Part of the IEC/EN 61290 family (other parts cover gain, noise figure, electrical spectrum analyzer methods, pump leakage and multi‑channel tests).

Keywords: EN 61290-5-1, IEC 61290-5-1, optical amplifiers, reflectance parameters, optical spectrum analyzer method, OFA, SOA, POWA, reflectance measurement.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 61290-5-1 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 2000. It constitutes a
technical revision. In this edition the applicability has been extended to all commercially
available optical amplifiers—not just optical fiber amplifiers.
