IEC 61280-2-13:2024 series defines a procedure for calculating the root-mean-square error vector magnitude of optical n-APSK signals from a set of measured symbols. It specifically defines the normalization of the reference states and a procedure for optimal scaling of the measured symbol states. The procedure described in this document applies to single-polarized optical signals as well as to conventional polarization-multiplexed signals with independently modulated polarization tributaries. In general, it is not advisable to apply these procedures without modification to signals, in which optical amplitude, phase, and polarization state are simultaneously modulated to encode the information data. This document does not specify any signal processing steps for extracting the symbols from the received optical signals, because these steps depend on the optical receiver and can vary with the type of the transmitted n-APSK signal. These and optional additional signal processing steps are defined in application-specific documents.

IEC 61169-69:2024, which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) for RF coaxial connectors with push-on coupling, typically for use in 50 Ω RF cables or micro-strips in microwave, telecommunication, wireless systems, and other fields (SMP3).
It specifies mating face dimensions for general purpose connectors – grade 2, dimensional details of standard test connectors-grade 0, gauging information and tests selected from IEC 61169-1, applicable to all detail specifications relating to series SMP3 RF connectors.
This specification indicates recommended performance characteristics to be considered when writing a detail specification and it covers test schedules and inspection requirements for assessment levels M and H.
The SMP3 push-on coupling structure series RF coaxial connectors with the characteristic of normative impedance 50 Ω are used with various kinds of RF cables or micro-strips in microwave, telecommunication, wireless systems, and other fields. The operating frequency limit is up to 65 GHz.
NOTE Imperial dimensions are the original dimensions since this is a very miniature RF connector. There is a concern that conversion to the metric system could lead to rounding errors which can lead to performance degradation from the original imperial design. The SMPM connector was released as an imperial design for this reason. All undimensioned pictorial information is for reference only.

This part of IEC 60793 describes three methods for determining and measuring the modal
bandwidth of multimode optical fibres (see IEC 60793-2-10, IEC 60793-2-30, and the
IEC 60793-2-40 series). The baseband frequency response is directly measured in the
frequency domain by determining the fibre response to a sinusoidaly modulated light source.
The baseband response can also be measured by observing the broadening of a narrow pulse
of light. The calculated response is determined using differential mode delay (DMD) data. The
three methods are:
• Method A – Time domain (pulse distortion) measurement
• Method B – Frequency-domain measurement
• Method C – Overfilled launch modal bandwidth calculated from differential mode delay
(OMBc)
Method A and method B can be performed using one of two launches: an overfilled launch
(OFL) condition or a restricted mode launch (RML) condition. Method C is only defined for A1-
OM3 to A1-OM5 multimode fibres and uses a weighted summation of DMD launch responses
with the weights corresponding to an overfilled launch condition. The relevant test method and
launch condition is chosen according to the type of fibre.
NOTE 1 These test methods are commonly used in production and research facilities and are not easily
accomplished in the field.
NOTE 2 OFL has been used for the modal bandwidth value for LED-based applications for many years. However,
no single launch condition is representative of the laser (e.g. VCSEL) sources that are used for gigabit and higher
rate transmission. This fact drove the development of IEC 60793-1-49 for determining the effective modal bandwidth
of laser optimized 50 μm fibres. See IEC 60793-2-10 and IEC 61280-4-1 for more information.

IEC 61757-7-3:2024 defines the terminology, structure, and performance characteristics of fibre optic voltage sensors using a polarimetric measurement method. The document specifies test methods and procedures for measuring key performance parameters of these sensors. It addresses only the voltage sensing element and not the additional devices that are unique to each application. The document does not specify the required performance values of optical polarimetric fibre optic voltage sensors, because these specifications depend on the designated application of the sensor and are typically defined by the user of the sensor. The required performance values are usually defined when designing a sensor for a specific application.

IEC TR 63323:2024 deals with a new proposal for an SC adaptor connector which includes a flexible retaining element on its top surface, compared to the SC standard adaptor.
With this solution, when the SC plug connector is in place, any accidental disconnection is difficult, as it employs an external tool or a particular unlocking manoeuvre.
This new adaptor is intended primarily for the home network customer optical fibre termination, but it can be used in every situation where safety issues are important (e.g. main distribution frames in central offices, cross-connect cabinets, street cabinets, termination boxes).
It consists of a push-latch-pull mating sequence connection with the assistance of a suitable tool.
This solution assures compatibility with the existing SC interface standard according to IEC 61754-4.

IEC 60793-1-41:2024 is available as IEC 60793-1-41:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60793-1-41:2024 describes three methods for determining and measuring the modal bandwidth of multimode optical fibres (see IEC 60793-2-10, IEC 60793-2-30, and the IEC 60793‑2‑40 series). The baseband frequency response is directly measured in the frequency domain by determining the fibre response to a sinusoidaly modulated light source. The baseband response can also be measured by observing the broadening of a narrow pulse of light. The calculated response is determined using differential mode delay (DMD) data. The three methods are: Method A – Time domain (pulse distortion) measurement Method B – Frequency-domain measurement Method C – Overfilled launch modal bandwidth calculated from differential mode delay (OMBc) Method A and method B can be performed using one of two launches: an overfilled launch (OFL) condition or a restricted mode launch (RML) condition. Method C is only defined for A1-OM3 to A1-OM5 multimode fibres and uses a weighted summation of DMD launch responses with the weights corresponding to an overfilled launch condition. The relevant test method and launch condition is chosen according to the type of fibre. NOTE 1 These test methods are commonly used in production and research facilities and are not easily accomplished in the field. NOTE 2 OFL has been used for the modal bandwidth value for LED-based applications for many years. However, no single launch condition is representative of the laser (e.g. VCSEL) sources that are used for gigabit and higher rate transmission. This fact drove the development of IEC 60793-1-49 for determining the effective modal bandwidth of laser optimized 50 µm fibres. See IEC 60793-2-10 and IEC 61280-4-1 for more information. This fourth edition cancels and replaces the third edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the addition of a direct reference for method A and method B.
