Agilent 81680A Tunable Laser (S+C band)

The HP Agilent 81680A option 072 is a Polarization Maintaining Fiber (PM) fibered Tunable Laser (TLS) with built-in wavelength control. It is mode-hop free with continuous output power making it suitable for critical DWDM component testing. The 81680A covers the wavelength range 1460nm to 1580nm. The Agilent HP 81680A has 2 outputs; one being a low SSE and the other a high power output at 6dBm. Many angled connectors are available for this TLS.
