The HP/Agilent 81642B is a tunable laser source delivering continuous, mode-hop free wavelength tuning across the C- and L-bands (1495–1640 nm) with +8.5 dBm output power. Built-in real-time wavelength metering ensures ±10 pm absolute accuracy, while a maximum tuning speed of 80 nm/s minimizes test time without sacrificing measurement confidence. Panda-type polarization-maintaining fiber output maintains a stable, well-defined state of polarization—critical for waveguide and integrated optical device characterization. An optional integrated optical attenuator extends the dynamic output power range beyond 60 dB, enabling flexible stimulus configurations for optical amplifiers and passive components alike. The module integrates directly into Agilent’s 8164B mainframe, scaling within broader test architectures.
