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.
