The Keysight 81960A is a fast-swept tunable laser source delivering precise wavelength control across the C-band and L-band spectrum. Operating from 1505 nm to 1630 nm, this compact instrument generates output power from +6 dBm to +14 dBm with ±10 pm wavelength accuracy during dynamic sweeps. Built for high-repetition-rate applications, the 81960A achieves scan speeds up to 200 nm/s (1528–1608 nm range) and supports bidirectional sweeping at better than 2 Hz repetition rates, enabling rapid real-time adjustments in production and development environments.
