Please help us customize your browsing experience, by selecting one the below.

Description

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.
