Select the pumping arrangement using the signal passband and transmission span. Pump output power and signal-band insertion loss are different quantities and must be evaluated separately.
Configuration options
| Configuration | Signal passband | Maximum output power |
|---|---|---|
| Third-order co-pump | 1500-1568 nm | ≤3 W |
| Multiplexed co-pump | 1500-1568 nm | ≤2 W combined |
| Supplemented co-pump | 1500-1568 nm | ≤2 W combined |
| Extended-band multiplexed pump | 1524 - 1572 nm | up to 2 W combined |
| Extended-band supplemented pump | 1524 - 1572 nm | up to 2 W combined |

Conditions and configuration notes
- A value in dBm describes optical power; a value in dB describes gain, loss or an optical budget. A link budget is not a distance in kilometres.
- Performance depends on channel loading, fibre losses and the selected operating point; family limits do not automatically apply together.
- The two multiplexed entries share a combined-power specification; they are not independently rated at that combined total.
- The third-order arrangement targets signal channels at 1542-1568 nm. Exact pump lines and seed powers need confirmation.
