The scenario
An FTTH OLT with two PON ports distributes service to 256 subscribers using dual-stage optical splitting (1:4 then 1:32), requiring a scalable and readable network diagram.
What is in this drawing
Read the decisions behind it.
01
Represented OLT as a core l3switch with two PON port links
02
Modeled each 1:4 and 1:32 splitter as a switch node for connection clarity
03
Aggregated 32 subscribers per secondary splitter into a cloud node labeled with the count
Reuse this structure for any FTTH/GPON distribution diagram where an OLT feeds multiple splitter stages and a large number of subscriber endpoints; adjust split ratios and counts per PON port.
