The AQ4321D is a Tunable Laser Source with precise wavelength control in the 1520 to 1620 nm range. It has excellent basic performance such as high-speed sweep, high stability, and narrow linewidth. These high-quality Tunable Laser Sources can accurately set wavelength range, accommodating various aspects of DWDM applications. Their high output, high SMSR, and high stability are excellent for evaluating optical fiber amplifiers, components, and DWDM systems. An internal hard drive and 3.5 inch floppy disk make test setups easy to store and recall. Additional features include a color LCD display with soft key menus for selecting functions and sub menus.

Features:

• High wavelength accuracy: ±10 pm (at 1520 nm)
• Accurately measures spectral characteristics of AWG, FBG, DWDM filters, etc.
• Ideal for the evaluation of optical amplifiers and DWDM Tx systems.
• Continuous wavelength tuning
• Wavelength range: 1480 to 1580 nm (AQ4321A) 1520 to 1620 nm (AQ4321D)
