Agilent / HP / Keysight 11980A
11980A Fiber-Optic Interferometer
This Lightwave Fiber Optic Interferometer is a Mach Zehnder interferometer of fixed delay.
It is used with an Agilent 71400 series or the Agilent 83810B lightwave signal analyzer.
It will allow you to measure chirp and frequency modulation (FM) on DFB lasers.
The traditional measurements of laser linewidth on single line lasers can also be made.
Wavelength range from 1250 to 1600nm
Insertion loss is 8dB
Delay time is 3.5µsec
