A remote amplifier element and its terminal pump form one link design. Select the pump order, seed arrangement and position of the gain element using a complete loss and power budget.
Configuration options
| Configuration | Main pump wavelength | Pump seed wavelength | Maximum output power |
|---|---|---|---|
| Single-wavelength pump | 148x nm | Not specified | ≤2 W |
| Dual-wavelength pump | 142x nm | 148x nm | ≤5 W |
| Second-order pump | 136x nm | 142x + 148x nm | ≤5 W |
| Cascaded third-order pump | 127x nm | 148x nm | ≤5 W |

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 x in 148x, 142x, 136x and 127x nm denotes an unspecified last digit; exact pump and seed wavelengths require confirmation.
- A blank seed-wavelength entry is left unspecified rather than interpreted as proof that no seed is required.
