IEC TR 62150-7: 2024 which is a technical report, provides simple calculation guidelines for the laser safety class of optical transceivers and transmitters, whose baseline standard is IEC 60825-1. The calculation methodology for Class 1 and Class 1M safety levels is the main scope of this document, because most of optical transceivers and transmitters are specified for these classifications. The calculations and classifications in this document follow IEC 60825-1, which specifically advises that laser safety classifications be based on tests that consider any reasonably foreseeable single-fault condition in the application of a transceiver or transmitter. More information can be found in IEC 60825-1:2014, 5.1.

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 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 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 63267-2-2:2024 defines the dimensional limits of an optical interface for reference connections necessary to meet specific requirements for fibre-to-fibre interconnection of non-angled and angled polished multimode reference connectors intended to be used for attenuation measurements in the field or factory. Several grades of reference connections are defined in this document.
The multimode reference connections are terminated to restricted IEC 60793-2-10 A1-OM2b to A1-OM5b fibre at the 850 nm band only.
The geometrical dimensions and tolerances of the specified reference connections have been developed primarily to limit the variation in measured attenuation between multiple sets of two reference connectors, and therefore to limit the variation in measured attenuation between randomly chosen reference connectors when mated with connectors in the field or factory.

IEC 63267-2-1:2024 defines a set of specified conditions for an enhanced macro bend of 50/125 µm, graded index multimode fibre optic connection that is maintained in order to satisfy the requirements of attenuation and return loss performance in a randomly mated pair of polished physically contacting (PC) fibres.
An encircled flux (EF) compliant launch condition in accordance with IEC 61300-1, at an operational wavelength of 850 nm, is used for determination of performance grades, based on lateral fibre core offset, numerical aperture (NA) mismatch, and fibre core diameter (CD) variation.
Fibre core angular offset is considered insignificant given the state-of-the-art and is excluded as a factor for attenuation estimation. Attenuation and return loss performance grades are defined in IEC 63267-1.

IEC 62343-2-1:2019 provides a reliability qualification test template for dynamic modules (DMs). The template describes the reliability qualification test items and provides information on requirements or options. Example test conditions are given for information purposes in Annex A. For reliability qualification purposes, some information about the internal components, parts and interconnections is needed. These internal parts are treated as black boxes. This document gives requirements for the evaluation of DM reliability by combining the reliability of such internal black boxes. The object of this reliability qualification test template is to provide a framework for the reliability qualification tests for DMs. Developers of reliability qualification tests for DMs determine the test conditions for each test item by referring to the examples in Annex A.
