(2+1)x1 vs (6+1)x1 PM Pump & Signal Combiner
Compare two-pump and six-pump PM pump-and-signal combiner architectures for fiber lasers and fiber amplifiers.
Use this page when
the system requires one PM signal path plus pump injection, and the main architecture question is pump-port count.
Quick comparison
| Selection point | (2+1)x1 | (6+1)x1 |
|---|---|---|
| Pump inputs | 1 or 2 pump ports in this product family | 6 pump ports |
| Pump wavelength | 800-1000 nm | 800-1000 nm |
| Signal wavelength | 1030-1080 or 1450-1600 nm | 1030-1080 or 1450-1600 nm |
| Signal IL | ≤0.5 dB | ≤0.7 dB (typ. 0.5) |
| Max power / pump | ≤50 / ≤100 / ≤200 W depending fiber | ≤50 / ≤100 / ≤200 W depending fiber |
| Main reason to choose | Lower pump-port count | Higher pump-port count |
RFQ rule: The fastest inquiry includes the application plus wavelength, power, fiber, connector and quantity. If one parameter is unknown, send the known conditions for engineering review.
Which one should you choose?
Choose (2+1)x1 when...
Choose (2+1)x1 when one or two pump inputs are enough for the architecture and you want the simpler pump-port configuration.
Choose (6+1)x1 when...
Choose (6+1)x1 when six pump inputs are required around one PM signal path.

Common questions
Is pump efficiency the same for every fiber option?
No. Published efficiency bands depend on the selected fiber configuration.
What information should be sent?
Pump count, pump wavelength, signal wavelength, input/output fiber, power per pump, signal power and preferred package.
Still not sure which configuration fits?
