IEC 62496-2-5:2022 defines a test method for folding flexibility inspection of flexible opto-electric circuits with a flexibility tester endurance tester and presents a guideline for a step stress test method for finding the predetermined minimum mechanical folding radii below which the flexible opto-electric circuits can be damaged by intended folding distortion. Here, test samples are used instead of products for the flexibility test of their flexible opto-electric circuits, and the test samples have the same material, layer structure, processing technology and equipment as the products.

IEC 62496-4-214:2020 defines the standard interface dimensions for a terminated waveguide optical circuit board (OCB) assembly (referred to simply as "assembly") using single-row thirty-two-channel connectors for polymer waveguides connected with a symmetric PMT connector.

IEC 62496-4-1:2019 defines the standard interface dimensions for a terminated waveguide optical circuit board (OCB) assembly (referred to simply as assembly) using single-row twelve-channel polymer waveguides for a PMT connector and a waveguide OCB that can be interconnected with a terminated MT ferrule.
Keywords: interface dimensions for a terminated waveguide optical circuit board (OCB)

IEC 62496-2:2017 specifies a method of defining the conditions for measurements of optical characteristics of optical circuit boards. The method comprises the use of code reference look-up tables to identify different critical aspects of the measurement environment. The values extracted from the tables are used to construct a measurement identification code, which, in itself, captures sufficient information about the measurement conditions, so as to ensure consistency of independently measured results within an acceptable margin. Recommended measurement conditions are specified to minimise further variation in independently measured results.

IEC/TS 62661-2-1:2013(E) gives guidelines for an optical backplane using optical fibre boards and multi-core right angle optical connectors with low bending loss multimode fibres (hereafter called low-loss RAO) to connect daughter boards to the optical backplane. Keywords: optical backplane, optical fibre boards, multi-core right angle optical connectors

IEC/TR 62658:2013(E) covers the roadmap of optical circuit boards, and its related packaging technologies including optical circuit board connectors and optical modules on boards. Keywords: optical packaging technology road map, roadmap of optical circuit boards

IEC 62496-2-4:2013 specifies the test method to decide whether to pass or fail an optical circuit board using direct illumination by a light. The input ports are directly illuminated and the optical intensity from the output ports of the optical circuit board is monitored using an area image sensor. Excess optical losses are the calculated from total detected intensities of light from a sample to be measured and from a control sample. This method is used to illuminate uniformly the input port of the optical circuit board (OCB) with a larger area than the core area, obtain the radiance of an area image from the corresponding output port of the OCB using an area image sensor, and evaluate whether to pass or fail using the radiance obtained compared to that of a control sample. The advantage of this test method is that the alignment procedure between a launch fibre and the OCB is not necessary. Key words: test method to decide whether to pass or fail an optical circuit board, OCB, area image sensor

IEC 62496-2-1:2011 describes the various methods to measure the optical attenuation and isolation of optical circuit boards (OCBs).

IEC 62496-2-2:2011 specifies the measurement procedures for dimensions related to interface information of optical circuit boards (OCB), defined in IEC 62496-4.

IEC 62496-4:2011 covers general information on the subject of Optical Circuit Board (OCB) interfaces. It includes normative references, definitions and rules for creating and interpreting the standard drawings.

IEC 62496-3:2011 covers general information on optical circuit board performance standards. It defines those tests and severities which form the performance categories or general operating service environments and identifies those tests which are considered to be product-specific.

IEC 62496-3-1:2009 defines the performance of flexible optical circuit boards (FOCBs) using unconnectorized optical glass fibres for controlled environment. This standard clarifies the requirements for quality classification of the flexible OCBs incorporating optical glass fibres.

IEC 62496-1:2008 applies to optical circuit boards possessing all of the following general features:
- transmit patterns with straight, cross, bending optical paths and input and output optical ports in plane;
- optical paths consisting of optical fibres and/or optical waveguides;
- controlled lengths of the optical paths, if required;
- may be combined with a printed electric circuit board, the functionality of which is outside the scope of this standard;
- to interconnect between optical components and the ability to mount components.
