The Keysight 8160xA tunable laser sources are designed with a common cavity laser module. They share a narrow linewidth and low spontaneous emission level, enabling excellent spectral loss measurement range in both the stopband and passband when used with the Keysight N774xA multi-port power meter or the Keysight 816xxx power meter module.
The built-in gas chamber and self-adjustment features ensure excellent long-term stability to minimize cost of ownership. Within the 8160xA series, cost-effective models and base models offer additional cost-effective options in terms of output power, tuning mode and speed, wavelength accuracy, and repeatability.
The 81608A cost-effective tunable laser source module delivers peak output power in excess of +12 dBm, at least 75 dB/nm above its spontaneous emission level. It performs bi-directional scanning up to 200 nm/s with typical wavelength repeatability of ±1.5 pm. This laser source offers a good balance of functional characteristics, performance and price, making it suitable for coherent transmission experiments and cost-effective component testing on the production line.
The 81608A tunable laser source is supported by the N7700A optical communications application software suite and, when used in conjunction with a power meter and polarization instrument, can measure spectral characteristics such as insertion loss, polarization dependent loss and dispersion. They provide excellent scanning wavelength accuracy and dynamic range.
