ICS 33.180 is a classification code in the International Classification for Standards (ICS) system. It covers "Fibre optic communications". The ICS is a hierarchical classification system used to organize international, regional, and national standards, facilitating the search and identification of standards across different fields.
There are 3685 standards classified under ICS 33.180 (Fibre optic communications). These standards are published by international and regional standardization bodies including ISO, IEC, CEN, CENELEC, and ETSI.
The International Classification for Standards (ICS) is a hierarchical classification system maintained by ISO to organize standards and related documents. It uses a three-level structure with field (2 digits), group (3 digits), and sub-group (2 digits) codes. The ICS helps users find standards by subject area and enables statistical analysis of standards development activities.

This document provides requirements and specific guidance for the safe operation and maintenance of optical fibre communication systems (OFCSs). In these systems, optical power is possibly accessible outside the confines of the transmitting equipment and/or at great distance from the optical source.
This document requires the assessment of hazard level at each accessible location of the OFCS as a replacement for product classification according to IEC 60825-1. It applies to the installed OFCS as an engineered, end-to-end assembly for the generation, transfer and receipt of optical radiation arising from lasers, light-emitting diodes (LEDs) or optical amplifiers, in which the transference is by means of optical fibre for communication and/or control purposes.
NOTE 1 Throughout this document, a reference to 'laser' is taken to include LEDs and optical amplifiers.
Individual components and subassemblies that fall under the definition of a laser product are subject to the applicable subclause(s) of IEC 60825-1. This document is applicable to individual components and subassemblies intended to be installed within OFCSs.
This document does not apply to optical fibre systems primarily designed to transmit optical power for applications such as material processing or medical treatment.
In addition to the hazards resulting from laser radiation, OFCSs possibly give rise to other hazards, such as fire.
This document does not address safety issues associated with explosion or fire with respect to OFCSs deployed in explosive atmospheres.
NOTE 2 The hazard presented by optical radiation emerging from a fibre is determined by the wavelength and power emerging from the fibre and also by the optical characteristics of the fibre itself (see Annex A).

If tests are performed on the connectors terminated as pigtails or patchcords for category OPHD, OP+ or OP+HD and the product passes these tests, the product will be automatically qualified or categorized as meeting the IEC standard for category OP. If tests are performed on the connectors terminated as pigtails or patchcords for category OP, and the product passes these tests, the product will be automatically qualified or categorized as meeting the IEC standard for category C or CHD.
This first edition cancels and replaces the first edition of IEC 61753-021-3 published in 2012.
This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) update of environmental categories (from U to OP), tests and their severities in accordance with IEC 61753‑1;
b) changes in the terms and definitions of the different types of test samples (pigtail test samples and patchcord test samples) used in the various tests to avoid confusion;
c) update of fibre naming conventions in accordance with IEC 60793‑2‑50 and addition of provisions for B‑657 fibres;
d) addition of all the attenuation and return loss grades defined in IEC 61753‑1;
e) deletion of the static side load test;
f) addition of provisions for rectangular ferrule connectors;
g) addition of the fibre optic connector proof test with static load – side pull;
h) update of the flexing of the strain relief test to use change of attenuation instead of transient loss;
i) addition of Annex B for visual examination of the outer cable sheath movement of reinforced cables as an additional requirement for change of temperature, cable retention and flexing of the strain relief tests.

IEC 60794-1-126:2026 defines the test procedures used to establish uniform requirements for mechanical performance - galloping. It applies to optical fibre cables like ADSS, OPGW or OPPC that can be exposed to galloping phenomena. See IEC 60794-1-2 for general requirements and definitions and for a complete reference guide to test methods of all types. This first edition cancels and replaces Method E26 of the first edition of IEC 60794‑1‑21 published in 2015. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Addition of "for ADSS" and "for OPGW and OPPC" in 4.7, a);
b) Addition of "L4" in Figure 1 and in 4.7, b);
c) Change of the specified static sag angle to ≤ 1,5±0,5°;
d) Improvement of Figure 1;

IEC 61753-022-13:2026 defines the minimum initial test and measurement requirements, and severities which multimode fibre optic connectors terminated as a pigtail or a patchcord satisfy in order to be categorized as meeting the IEC standard category OP+HP (Extended outdoor protected environment with additional heat dissipation), as defined in IEC 61753-1.
If tests are performed on the connectors terminated as pigtails or patchcords for category OP+HP, and the product pass, the product will be automatically qualified or categorized as meeting the IEC standard for categories OP+, OP, OPHD, C and CHD.

IEC 61757:2026 defines, classifies, and provides a framework of generic tests or measurement methods for characterizing and specifying fibre optic sensors, including their specific components and subassemblies. The requirements of this document apply to all related fibre optic sensor standards that are part of the IEC 61757 series. Other parts of the IEC 61757 series contain requirements that are specific to sensors that measure particular quantities, and to a particular style or variant of such a fibre optic sensor. This second edition cancels and replaces the first edition published in 2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) expansion of the list of metrological parameters; b) updates of the terms and definitions; c) updates of the normative references and bibliography; d) updates of the technical descriptions in Annex A.

IEC 61754-2: 2026 defines the standard interface dimensions for type BFOC/2,5 family of connectors.
This second edition cancels and replaces the first edition published in 1996. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) addition of Clause 2, Clause 3 and the Bibliography;
b) addition of the active device receptacle interface type;
c) revision of the ferrule grades to refer to the connector optical interfaces specified in the IEC 61755-3 series;
d) revision of the ferrule end face geometry to refer to the connector optical interfaces specified in the IEC 61755‑3 series and IEC 63267‑3 series;
e) improvement of the description of the characteristics of the resilient alignment sleeve for adaptor and rigid bore sleeve for active device receptacle;
f) harmonisation of the dimensions of reference A for the rigid bore sleeve with other connector interface standards in IEC 61754 series.

IEC 60794-1-136:2026 specifies procedures to determine the maximum allowable push force applied on cables during the installation by blowing. Currently this parameter is determined by a separate test on the cable before installation. The methods specified in this document apply primarily to low-diameter cables (microduct cables according to IEC 60794-5) without rigid strength elements (e.g. GRP rods).
