Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-39: Examinations and measurements - PC optical connector reference plug selection
The object of this part of IEC 61300 is to select Physical Contact (PC) optical connector plugs to be used as the reference plug in the return loss RL measurement and to define an acceptance return loss value RLa to be used in plug acceptance testing. This procedure is used to guarantee a certain return loss value RL when two plugs are randomly mated together.
