11. Using the OSICS SWT Module
This section explains how to operate the OSICS SWT via the SWT Unit Setup menu. For
more details on how to install and initialize the module into the OSICS Mainframe, see
section Installing and Connecting the OSICS Multifunction Platform, p. 21 .
11.1 OSICS SWT Presentation
Features The OSICS SWT is a full suite of fiber optic switch and shutter modules based on optical
prism technology.
• The 1x1 configuration is a shutter. It allows to block/pass an optical signal with high
isolation.
• The 2x(1x1) configuration is a 2x shutter. It features two 1x1 configurations.
The first one is called Shutter A-B, the second one Shutter 1-2. They can be operated
simultaneously as well as individually.
• The 2x2 switch configuration allows to cross (or not) two input and two output
channels.
• The 1x2 and 1x4 switch configuration features one common input/output channel
(Com), and 2 or 4 output/input channels (Ch1 and Ch2 or Ch1, Ch2, Ch3 and Ch4) to
be used sequentially.
The OSICS SWT module is fully bi-directional: you can use the module as 1 input and 2 or
4 outputs (see Figure 94, p. 137 ), or 1 output and 2 or 4 inputs (see Figure 95, p. 137 ),
depending on the needs of your measurement setup.
• In a standard configuration, it allows you to direct a laser signal from the common
channel Com to any output channel Ch1 to Chn , as shown in the following figure:
Figure 94: SWT Standard Configuration
• In a reverse configuration, you can direct any signal one after another from Ch1 to
Chn to the common channel Com as illustrated in the following figure:
Figure 95: SWT Reverse Configuration
The SWT optical-switch module can be combined with a variety of modular sources such
as tunable external cavity laser (T100), distributed feedback laser diode (DFB) and tunable
laser source (TLS), within the same OSICS multifunction platform.
