OPTICAL AMPLIFIERS – TEST METHODS –
Part 1-3: Power and gain parameters – Optical power meter method
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 61290-1-3 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 1998. It is a technical revision that includes the following significant changes. a) Optical power and gain parameters are both included in this revision. Therefore, International Standard IEC 61290-2-1 has been withdrawn. b) The applicability has been extended to all commercially available optical amplifiers – not just optical fiber amplifiers. This standard shall be read in conjunction with IEC 61291-1.

Unless otherwise specified, the optical source shall emit a continuous wave with the full width at half maximum of the spectrum narrower than 1 nm (‡).
A distributed feedback (DFB) laser, a distributed Bragg reflector (DBR) laser, an external cavity laser (ECL) diode , a light emitting diode (LED) with a narrow-band filter and a single line laser are applicable, for example. The suppression ratio for the side modes for the DFB laser, the dBR laser or the ECL shall be higher than 30 dB (‡). The output power fluctuation shall be less than 0,05 dB (‡), which may be better attainable with an optical isolator at the output port of the optical source. Spectral broadening at the foot of the lasing spectrum shall be minimal for laser sources; – wavelength-tunable optical source: This optical source shall be able to generate a wavelength-tunable light within the range specified in the relevant detail specification. Its optical power shall be specified in the relevant detail specification. Unless otherwise specified, the optical source shall emit a continuous wave with the Full Width at Half Maximum (FWHM) of the spectrum narrower than 1 nm (‡). An ECL or an LED with a narrow bandpass optical filter is applicable, for example. The suppression ratio of side modes for the ECL shall be higher than 30 dB (‡). The output power fluctuation shall be less than 0,05 dB, which may be better attainable with an optical isolator at the output port of the optical source. Spectral broadening at the foot of the lasing spectrum shall be minimal for the ECL; b) optical power meter: it shall have a measurement accuracy better than ±0,2 dB, irrespective of the state of polarization, within the operational wavelength bandwidth of the OA. A maximum optical input power shall be large enough [e.g. +20 dBm (‡)]. Sensitivity shall be high enough [e.g. –40 dBm (‡)]. A dynamic range exceeding the measured gain is required (e.g. 40 dB); c) optical isolator: Optical isolators may be used to bracket the OA. The polarization-dependent loss (PDL) of the isolator shall be better than 0,2 dB (‡). Optical isolation shall be better than 40 dB (‡).

The reflectance from this device shall be smaller than –40 dB (‡) at each port; e) polarization controller: this device shall be able to provide as input signal light all possible states of polarization (e.g. linear, elliptical and circular). For example, the polarization controller may consist of a linear polarizer followed by an all-fibre-type polarization controller, or by a linear polarizer followed by a quarter-wave plate rotatable by minimum of
90° and a half wave plate rotatable by minimum of 180°. The loss variation of the polarization controller shall be less than 0,2 dB (‡). The reflectance from this device shall be smaller than –40 dB (‡) at each port. The use of a polarization controller is considered optional, except for t
