The Keysight 8160xA tunable laser sources are based on a common cavity and laser module design. They share a narrow line width and a low spontaneous emission level that, in combination with the Keysight N774xA multiport power meters, or the Keysight 816xxx power meter modules, enables excellent spectral loss measurement ranges in both stop band and pass band. A built-in gas cell and self-adjustment capabilities ensure excellent long-term stability to minimize cost of ownership. Within the 8160xA family, the value and basic line models offer additional price-performance options based on output power, tuning modes and speed, wavelength accuracy and repeatability.
The 81608A value line tunable laser module offers a peak output power of more than +12 dBm, at least 75 dB/nm above its spontaneous emission level. It features a typical wavelength repeatability of ±1.5 pm at two-way sweeps up to 200 nm/s. The laser’s balance of features, performance and price makes it suitable for both coherent transmission experiments and cost-effective manufacturing-floor component testing.
The 81608A tunable laser source is supported by the N7700A photonic application suite software for spectral measurements of insertion loss, polarization dependent loss and dispersion in combination with power meters and polarization instruments. These provide optimal swept-wavelength accuracy and dynamic range.
Please also consider the new N7778C tunable laser source for a more compact version.
