The gain element is passive at its installation point and is spliced into the transmission fibre. Its location, pump delivery and gain requirements are determined together by the complete link budget.
Configuration options
| Configuration | Function | Numeric gain or noise limit |
|---|---|---|
| Transmit-side element | Remote optical gain | Not specified |
| Receive-side element | Remote optical gain | Not specified |
Technical details
- Electrical power at remote element
- No local active electronics; energy is delivered optically
- Gain and noise figure
- Configuration-specific; no numerical values provided
- Pump requirement
- Terminal pump matched to the element and span
Integration and delivery
- Installation
- In-line fibre splice; splice-box integration depends on the selected assembly
Conditions and configuration notes
- Passive describes the absence of local electronics; this is still an optically pumped gain medium.
- No numerical gain, noise figure, environmental rating or fixed placement distance is inferred.
Applications to discuss
- Long-span terrestrial links
- Submarine optical links
