The Keysight 81607A tunable laser module offers a typical wavelength repeatability of ±1 pm even during two-way sweeps with up to 200 nm/s, it is ideal for high-throughput test and automated adjustment of passive optical components. A signal-to-SSE ratio of 75 dB/nm, enabled by the new cavity and laser module design, provides an excellent isolation measurement range for the most demanding optical components.
