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.

IEC 62343:2017(E) applies to all commercially available optical dynamic modules and devices. 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.

IEC 62572-3:2016(E) deals with reliability assessment of laser modules used for telecommunication. The aim of this standard is to establish a standard method of assessing the reliability of laser modules in order to minimize risks and to promote product development and reliability and to establish means by which the distribution of failures with time can be determined. This should enable the determination of equipment failure rates for specified end of life criteria. In addition, guidance is given in IEC TR 62572-2. This third edition cancels and replaces the second edition published in 2014. This third edition constitutes a technical revision in which errors in Table 1 and Table 2 have been corrected.

1.1 Product definition This European Standard specifies the dimensional, optical, mechanical and environmental performance requirements of a Terminal Equipment Boxes for the FTTX networks. The Terminal Equipment Box will house the ONT/CPE (electronics) and it protects the optical fibres, splices and connectors from direct contact with the user. Optionally it can contain the network test interface, the power supply and the batteries. The performance of the electronics, power supply or batteries are not part of this document. 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
