The optical performance for the fibre optic contacts relates to the insertion and return losses measured at the junction of the
fibre to fibre interface. These losses are caused mainly by minute geometrical effects of the critical alignment components
and deviations in the fibre core and cladding dimensions.
The insertion loss results for multi-mode and single-mode fibres are given whereas the return loss values are provided for
single-mode fibres only.
Insertion and return losses are expressed in decibels (dB). The data shown in the diagrams below correspond to numerous
matings using various batches of optical fibres and connectors.
