IEC 62134-1:2009 establishes uniform generic requirements for fibre optic closures. This standard does not cover test and measurement procedures, which are described in IEC 61300 series. The main changes with respect to the previous edition are:
- addition and rewording of some terms and definitions;
- reconsideration of type, style and variant in the requirements;
- removal of quality assessment procedures.

This part of IEC 61757 defines terminology, structure, and a characteristic test method of an
optical current sensor using the polarimetric method. It addresses the current sensing element
only and not the additional devices that are unique to each application. Generic specifications
for fibre optic sensors are defined in IEC 61757.
As the specifications of optical polarimetric fibre current sensors required by each user vary
depending on the application, this document does not define the required performance values.
The required performance values are defined when designing a sensor according to the specific

This part of IEC 61757 defines detail specifications for distributed temperature measurement
by a fibre optic sensor, also known as fibre optic distributed temperature sensing (DTS). DTS
includes the use of Raman scattering, Brillouin scattering and Rayleigh scattering effects. In
addition, Raman scattering and Rayleigh scattering based measurements are performed with
a single-ended fibre configuration only. Brillouin scattering based measurements are
performed with a single-ended fibre or fibre loop configuration. The technique accessible from
both sides at same time (e. g. Brillouin optical time domain analysis, BOTDA) is referred to
here as a loop configuration. Generic specifications for fibre optic sensors are defined in
IEC 61757-1:2012.
This part of IEC 61757 specifies the most important DTS performance parameters and defines
the procedures for their determination. In addition to the group of performance parameters, a
list of additional parameters has been defined to support the definition of the measurement
specifications and their associated test procedures. The definitions of these additional
parameters are provided for informational purposes and should be included with the sets of
performance parameters.
A general test setup is defined in which all parameters can be gathered through a set of tests.
The specific tests are described within the clause for each measurement parameter. This
general test setup is depicted and described in Clause 4 along with a list of general
information that should be documented based upon the specific DTS instrument and test
setup used to measure these parameters as per IEC 61757-2-2.
Annex A provides a blank performance parameter table which should be used to record the
performance parameter values for a given DTS instrument and chosen optical test setup
configuration.
Annex B provides guidelines for optional determination of point defect effects.

It describes the products covered by the IEC 62343 series, defines terminology, fundamental considerations and basic approaches. The object of this document is to: establish uniform requirements for operation, reliability and environmental properties of dynamic modules (DMs) to be implemented in the appropriate DM standard, and provide assistance to the purchaser in the selection of consistently high-quality DM products for his particular applications, as well as in the consultation of the appropriate specific DM standard(s). This document covers performance templates, performance standards, reliability qualification requirements, hardware and software interfaces and related testing methods. Since a dynamic module integrates an optical module/device, printed wiring board, and software/firmware, the standards developed in the series will mimic appropriate existing standards. On the other hand, since "dynamic module" is a relatively new product category, the dynamic module standards series will not be bounded by the existing practices where requirements differ. The safety standards as related to dynamic modules are mostly optical power considerations, which is covered by IEC TC 76: Optical radiation safety and laser equipment.

These are covered by another EN document, EN 50700. This specification contains the initial, start of life optical, mechanical and environmental performance requirements of the optical fibre termination in a Terminal Equipment Box, in order for it to be categorized as an EN standard product. 1.2 Operating environment The tests selected combined with the severity and duration is representative of indoor and outside plant for above ground environments defined by: EN 61753-1 Category C Controlled environment 1.3 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this specification does not guarantee the reliability of the product. This should be predicted using a recognised reliability assessment programme. 1.4 Quality assurance Compliance with this specification does not guarantee the manufacturing consistency of the product. This should be maintained using a recognised quality assurance programme. 1.5 Allowed fibre and cable types All EN 60793-2-50 fibres can be stored in the Terminal Equipment Box with a minimum storage radius of 20 mm (up to a length of maximum 2 m). Smaller storage radii down to 15 mm are possible with the EN 60793-2-50 B6A fibre types, but in this case the reduction in mechanical reliability should be taken into account (see Annex A).

IEC TR 62343-6-9:2015(E) which is a Technical Report, describes a study of the impact of WSS dynamic crosstalk on the optical network and includes dynamic crosstalk measurement examples for three types of WSS. The generating mechanism and the generation factor of dynamic crosstalk in WSS are clarified, and the evaluation of same-channel crosstalk and different-channel crosstalk is shown to be necessary. Keywords: WSS, wavelength selective switch

IEC 62343-5-1:2014(E) contains the measurement method of gain tilt settling time for a dynamic gain tilt equalizer (DGTE) to change its gain tilt from an arbitrary initial value to a desired target value. 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: change in the title and changes in performance parameter names. Keywords: dynamic gain tilt equalizer (DGTE)

IEC TR 62343-6-7:2015(E) which is a technical report, describes optical channel monitor modules, one of several important classes of dynamic modules that are used in dynamic optical networks. This report includes a description of the necessity of optical channel monitors, specifically in the context of dynamic optical networks, and how this is driving feature and performance requirements. This technical report surveys the different categories of optical channel monitor technologies that are being used and highlights some of their unique characteristics. Also described are different possible approaches for characterizing and specifying the performance of optical channel monitor modules. Keywords: optical channel monitor modules, dynamic optical networks, dynamic modules

IEC 62656-1:2014 specifies the logical structure for a set of spreadsheets, used as "data parcels", to define, transfer and register product ontologies. The spreadsheet interface structure defined in this part of IEC 62656 contains the following: - Definition and specification of the logical structure and layout of the spreadsheet interface for definition, transfer, and registering of a reference dictionary; - Definition and specification of library instance data belonging to a class of a reference dictionary described by a set of spreadsheets conformant to this part of IEC 62656; - Definition and specification of the meta dictionary that enables the definition and transfer of a reference dictionary as a set of instance data conforming to the meta dictionary; - Definition and specification of the meta-model as data that enables the definition and transfer of a reference dictionary as a set of instance data conforming to the meta-meta-dictionary; - Specification of the mapping between the dictionary data expressed in the spreadsheet format and the EXPRESS model specified by IEC 61360-2/ISO 13584-42 (with some elements of ISO 13584-25); - Description of the basic semantic mapping between the dictionary data expressed in the spreadsheet formats defined in this part of IEC 62656 and that of DIN 4002.
