b Press Curve Fit to display the curve fit setup panel.
c The Algorithm field should be set to Sellmeier-5.
d The f''(min) number in the Equation window is the swept Dispersion Slope at
Lambda-Zero. Compare this number to the result measured at the
factory. The result should match within ±0.125 ps/nm
sured value.
Port 2 Stepped GD and Length Measurements
1 Press Recall to recall the state file D:\ODA\IVF_PORT2_STEPPED.ODA.
2 Repeat the "Port 1 Stepped GD and Length Measurements"
substituting Optical Input Port 2 where appropriate.
Port 2 Swept GD Measurement
1 Press Recall to recall the state file D:\ODA\IVF_PORT2_SWEPT.ODA.
2 Repeat the "Port 1 Swept GD Measurement"
Optical Input Port 2 where appropriate.
Lambda-Zero
The zero-dispersion wavelength of dispersion-shifted single-mode fiber
has a temperature coefficient of approximately
temperature at which the Factory Data measurements were performed is
listed on the factory-provided data sheet. If the On-Site Verification is
performed at a different temperature, use the following formula to adjust
the post-installation results for comparison with the Factory Data. All
temperatures are in
degrees C.

Dispersion Slope at Lambda-Zero
The dispersion slope at the zero-dispersion wavelength, expressed in
2
ps/nm , is approximately constant with temperature. Thus no temperature
correction is necessary.
