IEC 61755-1:2005

This part of IEC 61755 covers singlemode optical interfaces. It includes references, document structure details, definitions, preferred grades and the rules under which an optical interface is created. This standard defines the location of the fibre core in relation to the datum target and the following key parameters: lateral offset, end face separation, end face angle, end face high index layer condition. It also defines standardised test methods where appropriate.
