A box can be installed on a vertical indoor or outdoor surface above ground level. If the box is required to be relocatable with cables attached, the following additional tests are expected to be performed:
-   cable bending;
-   cable torsion.
This document specifies the number of splice trays and splice capacity for each fibre separation level. The maximum capacity is 288 splices. For housings with a higher number of splices, EN 50411 4 1 (street cabinets) can be used.

This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to IEC 60794‑1‑23:2019:

IEC 63185:2025 relates to a measurement method for complex permittivity of dielectric substrates at microwave and millimeter-wave frequencies. This method has been developed to evaluate the dielectric properties of low-loss materials used in microwave and millimeter-wave circuits and devices. It uses higher-order modes of a balanced-type circular disk resonator and provides broadband measurements of dielectric substrates by using one resonator, where the effect of excitation holes and that of fringing fields are taken into account accurately on the basis of the mode-matching analysis.
This second edition cancels and replaces the first edition published in 2020. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) the upper limit of the applicable frequency range has been extended from 110 GHz to 170 GHz;
b) circular disk resonators used for the measurements now include one with waveguide interfaces;
c) in calculating the complex permittivity from the measured resonant properties, the fringing fields are now accurately taken into account based on the mode-matching analysis.

IEC 62037-3:2025 defines the impact test on coaxial connectors to evaluate their robustness against weak connections and particles inside the connector, as independently as possible from the effects of cable passive intermodulation (PIM). For other connectors (e.g. panel mounted connectors), the cable can be replaced by an adequate transmission line (e.g. airline, stripline). In order to evaluate the effects of mechanical stresses on the connectors, a series of impacts is applied to the connectors while measuring the PIM.
This third edition cancels and replaces the second edition published in 2021. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) impact test requirements for multi-channel connectors added;
b) method for calculating impact energy added for connector shapes other than round;
c) revised test considerations for achieving maximum PIM in reverse (reflected) PIM measurements;
d) added clarification that PIM tests reports shall include the maximum PIM value measured.

This edition includes the following significant technical changes with respect to the previous edition:
a) Change of test conditions harmonizing with IEC 61753-1: 2018.

IEC 61753-086-02:2025 contains the minimum initial performance, test and measurement requirements and severities which a fibre optic pigtailed 1 490/1 550 nm downstream and 1 310 nm upstream wide wavelength division multiplexing (WWDM) passive optical network (PON) device will satisfy in order to be categorized as meeting the requirements of category C (indoor controlled environment), as defined in IEC 61753-1:2018, Annex A. WWDM is defined in IEC 62074-1. Annex B gives general information for these PON WWDM devices.
This first edition cancels and replaces the first edition of IEC 61753-086-2 published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) Change of test conditions harmonizing with IEC 61753-1: 2018.

IEC 62037-8:2025 defines a radiated passive intermodulation (PIM) test to determine PIM levels generated by a device or object when it is exposed to RF radiation. This test can be conducted on any material or object and is not limited to devices designed to propagate RF signals. This test can be conducted as either a near field or far field test as defined by the test specification in an outdoor test site or in an anechoic test chamber.
This second edition cancels and replaces the first edition published in 2021. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:

REN/MSG-TFES-1138

IEC 62037-1:2025 deals with the general requirements and measuring methods for intermodulation (IM) level measurement of passive RF and microwave components, which can be caused by the presence of two or more transmitting signals. The test procedures given in this document give the general requirements and measurement methods required to characterize the level of unwanted IM signals using two transmitting signals. The IEC 62037 series addresses the measurement of PIM but does not cover the long-term reliability of a product with reference to its performance. This third edition cancels and replaces the second edition published in 2021. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) added clarification that PIM generation is typically frequency dependent and noted that testing with swept or multiple fixed frequencies often provides more accurate results;
