Choosing Setup Parameters for
Your Device
A list of characteristics, suggestions and relationships are provided for a
variety of device types. For more information on the measurements that
you can make, refer to "Measurement Concepts" on page 31. For more
information on the instrument functions, refer to "Function Reference" on
page 87.
Transmission Fiber (All Types)
Characteristics
• Large range of dispersion values across the wavelength range
• Broadband device
• Smoothly changing group delay with relatively little fine structure
• Group delay is easy to curve fit using conventional model curves
• Differential group delay (DGD) may exhibit multiple peaks and valleys
• Approximately 0.25 dB/km attenuation
The relatively smooth and analytic behavior of the group delay of this
device makes it possible to use larger wavelength increments and lower
modulation frequency without loss of wavelength resolution. The
following discussion provides setup parameter information specific to
each device.
