Agilent/Keysight 81682B,Agilent Keysight 81682B Optical Source

The Agilent/Keysight 81682B is a tunable laser source delivering precise wavelength control and high-power optical output across the S- and C-bands. Operating from 1460 nm to 1580 nm with mode-hop-free tuning, it reaches maximum output power of +8 dBm and achieves tuning speeds to 80 nm/s. The integrated real-time wavelength meter provides absolute accuracy of ± 10 pm, while typical repeatability reaches ± 0.5 pm. Continuous sweep capability across the full wavelength range eliminates mode hops—critical for DWDM component characterization and optical amplifier testing. The Panda-type polarization-maintaining fiber output ensures stable, polarized light for precision measurements on integrated optical devices and passive components.
