Notes:
These figures reflect requirements of AS/NZS ISO/IEC14763.3:2012
These figures are based on 1. utilising a Light Source or Light source and associated mode conditioning device that produces the correct modal launch conditions 2. utilising test cords with reference connectors that meet the current standard
