Product Description：
HP 81680A is a polarization-maintaining optical fiber (PM) tunable laser (TLS) with built-in wavelength control. No mode jump, continuous output power, suitable for key DWDM component test.
Features:
1. Designed for c-band
2. Continuously scan the whole wavelength range
3. The source of high dynamic range is low output
4. Test high-power optical fiber output with optical amplifier
5. Built-in real-time wavelength meter
6. Mode-free adjustment for the whole wavelength range
7. Both types of optical fiber output are equipped with Panda polarization maintenance optical fiber.
Main technical specifications:
