The Keysight 81600B Tunable Laser Source Family comprises the most versatile and high performance tunable laser sources on the market. It allows WDM developers and manufacturers to dramatically reduce test cost, and increase profits by quick return-on-investment. The Keysight 81600B family enables the most precise characterization of advanced optical components with its fast and accurate sweep across the entire wavelength range and specified accuracy during the sweep. Signal output with low spontaneous emission (SSE) permits measurement of filters with highest dynamic range.

Benefits

Fewer instruments and better measurement uncertainties through the built-in attenuator and wavelength meter.

Built-in coherence control unit to reduce interference effects caused by the DUT design or DUT termination.

Variable sweep speed to easily adapt the source to your changing test and accuracy needs.

Wide tuning range for the characterization of broadband components with one instrument and one connection.

External wavelength locking capability to allow for easy open and closed-loop control of precision wavelength tuning: use a suitable analog input signal e.g. generated by locking the laser to an absorption cell.

The high optical output power with built-in attenuator enables you to stimulate and characterize optical amplifiers and receivers, or to split the optical signal among different components and test stations.

Highest measurement range through low spontaneous source emission (low SSE), Signal to SSE Ratio >70 dB/nm

Variable sweep speed up to 80 nm/s

Wide tuning range units to cover all transmission bands: 1260 nm 1640 nm

Built-in wavelength meter with excellent wavelength accuracy 3.6 pm

High optical output power up to +9 dBm with built-in high performance 60 dB attenuator
