Use the actual span fibre, signal band and loss map to choose a counter-pumping configuration. The source powers below are pump outputs rather than amplified signal powers.
Configuration options
| Configuration | Maximum output power | Maximum signal-band insertion loss |
|---|---|---|
| Conventional counter-pump | ≤1.5 W | 3.8 dB |
| Second-order counter-pump | ≤3 W | 3.8 dB |
| Third-order counter-pump | ≤5 W | 4.0 dB |
| Extended-band counter-pump | up to 2 W | 3.8 dB |

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 extended-band table states 1524-1572 nm. It does not assign that same operating range to every other pump option.
