Fibre optic interconnecting devices and passive components. Basic test and measurement procedures - Examinations and measurements. Physical contact (PC) optical connector reference plug selection for return loss measurements not-eligible represented in diagrams1 Scope The objective of this part of IEC 61300 is to select non angled physical contact (PC) optical connector plugs for use as the reference plug in the return loss RL measurement and to define an acceptance return loss value RLa for use in plug acceptance testing. This procedure is for use to guarantee a certain return loss value RL when two plugs have been successfully tested against the reference connector when randomly mated.
