How does C++ band differ from standard C-band?

C++ band covers a wider spectrum (1524~1572 nm, 48 nm bandwidth) compared to standard C-band (1528~1569 nm, 41 nm), with ≤2.5 dB flatness vs ≤2 dB.

What is the difference between fixed and tunable versions?

Fixed power provides constant output. Tunable allows 10%~100% power adjustment. Both are available at different price points.

C++ ASE Broadband Source | Omni Wavelength

Name: C++ Band ASE Broadband Light Source
Brand: Laser Instrument Store
SKU: ASE-C++-10-SM-M
Availability: InStock

The C++ band ASE broadband light source uses rare-earth fiber spontaneous emission to provide broad spectral coverage from 1524 to 1572 nm with maximum output power up to 200 mW. It covers a wider spectral range than standard C-band sources with ≤2.5 dB flatness, excellent spectral characteristics, and extremely low DOP. Available in fixed power and tunable power (10%~100%) versions with SMF-28 fiber. Package options include M15/M20 module and B1 benchtop forms. Suitable for fiber component testing, EDFA amplifier characterization, and FBG sensing applications.
