13.5.1 Insertion Ahead of 16/32-way Splitters Feeding ONUs/ONTs

In this case the most practical approach is to replace 1x16 (or 1x32) way splitters with 2x16 (or 2x32) way splitters to create an

insertion point, as 1xN and 2xN way splitters have virtually same insertion loss and therefore the overall system optical power

budget remains unchanged. The example here is typical/representative and different splitting ratios are possible.

13.5.2 Insertion Ahead of EDFA / 16/32-way Splitter / ONUs/ONTs

In this case the most practical approach is to insert a splitter, filter or a coupler/tap (for example 90:10 coupling ratio) ahead of

the EDFA to create an insertion point. A coupler is a practical solution to obtain the required ΔP optical power level difference

between incident and inserted optical wavelengths.
