DIN EN 61755-1:2013-03

This part of IEC 61755 covers singlemode fibre optic interfaces. It includes references, document structure details, definitions, and preferred optical connection grades. The grades are based on random mated connections between two optical connector populationsaccording to prescribed characteristics. This document also describes 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 and end face high index layer condition. It also defines standardised test methods where appropriate.
