Calculate optical power budget for fiber links
Enter the total fiber link length in kilometers
Specify fiber attenuation coefficient (0.35 dB/km for G.652D @ 1310nm)
Count the number of fusion splices and connectors in the link
Get total loss budget and recommendation for transceiver selection
Calculate the total optical loss for a fiber link to verify transceiver compatibility and identify over-budget links.
Typical optical power budgets for common transceiver types
| Transceiver Type | Typical Budget | Max Range |
|---|---|---|
| 1G SFP (1310nm) | ≤ 11 dB | ~10 km |
| 1G SFP LX (1310nm) | ≤ 15 dB | ~20 km |
| 10G SFP+ (1310nm) | ≤ 12 dB | ~10 km |
| 25G SFP28 (1310nm) | ≤ 10 dB | ~10 km |
