Tunable laser module for making spectral measurements of passive fiber-optic components
The tunable laser delivers 200nm/s sweep speed and increased acceleration, combined with the dynamic accuracy specifications needed for measuring dense-wavelength division multiplexing (DWDM) components, all packaged in a compact module. The new and unique capability of dynamically specified sweeps in both directions enhances the repetition rate to 2 Hz for real-time use in adjustment and calibration procedures. The 81960A module is designed for making spectral measurements of passive fiber-optic components, where engineers need results with high wavelength accuracy and dynamic range. It offers up to +14 dBm of output power, adjustable down to +6dBm.
Engineers can take full advantage of the laser’s swept-wavelength measurements by using the N7700A software suite. The laser’s high performance in continuous sweeps complements the N7700A-100 single-sweep polarization-dependent loss and insertion loss measurement engine. The dynamic wavelength accuracy will satisfy the test needs for many DWDM components. The 81960A’s speed is best harnessed with the new N7700A-102 fast spectral loss engine, which synchronizes the laser with N7744A or N7745A power meters to produce power and loss spectra in a convenient graphical display. The wavelength resolution and 50- to 60-dB dynamic range surpass comparable measurements by an optical spectrum analyzer, with repetition rates better than 2 Hz for filter component adjustment and calibration.
