Estimate whether a PON ODN link is feasible by checking OLT transmit power, ONU/ONT receiver sensitivity, PLC splitter insertion loss, feeder cable, drop cable, connector pairs, splices and reserve margin. Use this page for GPON, XGS-PON, EPON and FTTH splitter planning.
| Splitter Ratio | Planning Loss Used | Common FTTH Use | Design Note |
|---|---|---|---|
| 1:2 | 3.8 dB | Small branch / two-stage first split | Useful for cascaded designs. |
| 1:4 | 7.4 dB | Distribution point | Often paired with 1:8 or 1:16. |
| 1:8 | 10.7 dB | FAT / floor box | Good balance between coverage and budget. |
| 1:16 | 13.9 dB | Neighborhood distribution | Check connector and splice count carefully. |
| 1:32 | 17.2 dB | Common GPON FTTH split | Usually feasible with proper ODN design. |
| 1:64 | 20.8 dB | High-density FTTH split | Can be single-stage or 1:8 × 1:8. |
| 1:128 | 24.2 dB | Very high split design | Requires strict power budget verification. |
Copy this structured checklist when asking ZION for FTTH drop cable, PLC splitter, FAT, ODF, patch cord, pigtail and adapter selection. It is formatted for email, WhatsApp, CRM notes and inquiry forms.
| Status | Condition | Meaning | Recommended Action |
|---|---|---|---|
| Pass | Margin after reserve ≥ 0 dB | The selected ODN design keeps the reserve margin. | Confirm actual OLT/ONU optical class, splitter datasheet and field test requirements. |
| Warning | Raw budget is positive, but reserve is consumed or overload risk exists | The link may register, but field variation can create risk. | Reduce split ratio, shorten route, reduce connectors or use higher optical class. |
| Fail | Passive loss exceeds available optical budget | The estimated received power is below receiver sensitivity. | Redesign the ODN before quotation or deployment. |
