Key performance specifications
- 1310 and 1550 nm
- 20 mW output power
- CW power stability: ±0.03 db (24h)
- Output attenuation
The Keysight 81657A Fabry-Perot laser source is a dual-wavelength module to be used in conjunction with optical power meter modules for insertion loss, optical return loss, and PDL measurement of broadband components and fiber. The 81657A Fabry-Perot lasers are insensitive to back reflections and are stabilized for short and long-term applications.
Single- and dual-wavelength source modules are available with an output power of up to +13 dBm. You can attenuate the output power of the sources for applications requiring lower power.
