9 Switching Optical Routes
Typical Applications
This section provides some examples of typical test configurations that
demonstrate how a 8159xB Optical Switch module can be used to achieve
test automation, and improve test repeatability.
Selecting a Laser Source
In Figure 146 on page -244, a 81591B 1x2 Optical Switch is used to select
one of two different sources (different wavelengths) as the input to the
DUT.

Selecting Measurement and Calibration Paths
In Figure 147 on page -244, a 81591B 1x2 Optical Switch is used to select
between the measurement path and the calibration path.
