This part of IEC 61280 is applicable to the measurement of attenuation and determination of polarity and length of installed multimode and single-mode optical fibre cabling plant, terminated with MPO connectors, using test equipment having an MPO interface. This cabling plant can include multimode or single-mode optical fibres, connectors, adapters, splices, and other passive devices. The cabling can be installed in a variety of environments including residential, commercial, industrial, and data centre premises, as well as outside plant environments.

In this document, the optical fibres that are addressed include sub-categories A1-OMx, where x = 2, 3, 4 and 5 (50/125 μm) multimode optical fibres, as specified in IEC 60793-2-10, and category B-652 and B-657 (9/125 μm) single-mode optical fibres, as specified in IEC 60793-2-50. The attenuation measurements of the other multimode and single-mode categories can also be made using a light source and power meter (LSPM) or optical time domain reflectometer (OTDR) utilising an internal or external optical switch having one MPO interface. Multimode measurements are made with an 850 nm source because transceivers used for parallel optics applications having an MPO interface only operate at 850 nm; 1 300 nm measurements are optional. Single-mode measurements are made with a 1 310 nm and/or 1 550 nm source because transceivers used for parallel optics applications having an MPO interface operate at these wavelengths. This document does not include descriptions of cabling that is not exclusively MPO to MPO.

This part of IEC 61156 describes cables intended to be used for transmission of 1 Gbit/s over a single twisted pair for office, home and industrial application. An example of existing application is 1000BASE-T1, see ISO/IEC TR 11801-9906[1]. The transmission characteristics of these cables are specified up to a frequency of 600 MHz and at a temperature of 20°C. The cable type recognised is intended to be used for the work area wiring of shielded channels with a nominal length of 40 m. Possible designs are U/FTP, X/UTP and X/FTP, where X stands for F, S or SF.

These cables may comprise more than one pair in case several systems are operated in parallel. In this case, refer to clause 7 of this document.

The cables covered by this International Standard are intended to operate with voltages and currents normally encountered in communication systems. While these cables are not intended to be used in conjunction with low impedance sources, e.g. the electric power supplies of public utility mains, they are intended to be used to support the delivery of low voltage remote powering applications.

It specifies the IEC 63171 standard series common dimensions, mechanical, electrical and transmission characteristics and environmental requirements as well as required test specifications.

Within their own type, the shielded and unshielded connector are interoperable for their internal transmission performance and can be exchanged; the shielded version has improved EMC and coupling properties.

This part of the IEC 61784‑3 series explains some common principles that can be used in the transmission of safety-relevant messages among participants within a distributed network which use fieldbus technology in accordance with the requirements of IEC 61508 (all parts)[1] for functional safety. These principles are based on the black channel approach. They can be used in various industrial applications such as process control, manufacturing automation and machinery.

This part and the IEC 61784-3-x parts specify several functional safety communication profiles based on the communication profiles and protocol layers of the fieldbus technologies in IEC 61784-1, IEC 61784-2 and IEC 61158 (all parts). These functional safety communication profiles use the black channel approach, as defined in IEC 61508. These functional safety communication profiles are intended for implementation in safety devices exclusively.

NOTE 1 Other safety-related communication systems meeting the requirements of IEC 61508 (all parts) can exist that are not included in IEC 61784-3 (all parts).

NOTE 2 It does not cover electrical safety and intrinsic safety aspects. Electrical safety relates to hazards such as electrical shock. Intrinsic safety relates to hazards associated with potentially explosive atmospheres.

All systems are exposed to unauthorized access at some point of their life cycle. Additional measures need to be considered in any safety-related application to protect fieldbus systems against unauthorized access. IEC 62443 (all parts) will address many of these issues; the relationship with IEC 62443 (all parts) is detailed in a dedicated subclause of this document.

NOTE 3 Implementation of a functional safety communication profile according to this document in a device is not sufficient to qualify it as a safety device, as defined in IEC 61508 (all parts).

NOTE 4 The resulting SIL claim of a system depends on the implementation of the selected functional safety communication profile within this system.

This part of IEC 63182 specifies the dimensions of magnetic powder cores.

It is intended that this standard will include magnetic powder cores which are widely used and referenced in industry, either because they are included in national standards, or because they are seen to have broad-based use in industry. Where applicable, it is intended that the existing industrial name for each standard part should appear with the part within this series.

This standard also gives guidelines on the allowable limits of surface irregularities of magnetic powder cores. It should be considered as a general specification useful in the dialogue between magnetic powder core manufacturers and users about surface irregularities.

The objective of this part of IEC 62433 standard is to describe the extraction flow for deriving an immunity macro-model of an Integrated Circuit (IC) against  conducted Electrostatic Discharge (ESD) according to IEC 61000-4-2 and Electrical Fast Transients (EFT) according to IEC 61000-4-4.

The model addresses physical damages due to overvoltage, thermal damage and other failure modes. Functional failures can also be addressed.

This model allows the immunity simulation of the IC in an application. This model is commonly called Integrated Circuit Immunity Model Conducted Pulse Immunity, ICIM-CPI.

The described approach is suitable for modelling analogue, digital and mixed-signal ICs.  Several terminals of an IC can be part of a single model (e.g. input, output and supply pins). The implementation of the model is capable of representing the non-linear behaviour of overvoltage protection circuits.

The model can be implemented for the use in different software tools for circuit simulation in time-domain.  The described modelling approach allows simulating device failure due to ESD or EFT at component and system level considering all components necessary for the immunity simulation of an IC, such as a PCB or external protection elements.

This document demonstrates, in detail, the construction of models in a defined XML-based format which is suitable for the exchange of models without any deeper knowledge of the semiconductor circuit. However, the model functionality can be implemented in different formats including, but not limited to, tables, SPICE netlists, hardware description languages such as VHDL-AMS and Verilog-A.

This document provides:

the description of ICIM-CPI macro model elements representing electrical, thermal or logical behaviour of the IC.
