The Agilent 81689A compact tunable laser is specially designed for the C- Band. It allows you to add more flexibility to your test system for DWDM passive component test. Features Specially designed for the C-Band Saturating optical amplifiers for dense-WDM transmission systems Configuring multi-channel test beds for DWDM transmission systems Continuous sweep through full wavelength range Output equipped with either standard single-mode fiber or Panda type polarization maintaining fiber Key Specifications: Wavelength Range: 1525nm to 1570nm Output Power: >/= 6dBm Power Stability: ¡À0.03dB over 1 hour at constant temp Supplementary performance characteristics Modulation Internal digital modulation 50% duty cycle, 200 Hz to 300 kHz. >45% duty cycle, 300 kHz to 1 MHz. Modulation output (via Mainframe): TTL reference signal. External digital modulation > 45% duty cycle, fall time < 300 ns, 200 Hz to 1 MHz. Modulation input (via Mainframe): TTL signal. External analog modulation ¡Ý ¡À15% modulation depth, 5 kHz to 1 MHz. Modulation input: 5 Vp-p Coherence control (81649A/81689B) For measurements on components with 2 m long patchcords and connectors with 14 dB return loss, the effective linewidth results in a typical power stability of < ¡À0.025 dB over 1 minute by reducing interference effects in the test setup.
