switch assemblies for test and
measurement applications
• Network monitoring and testing
• Sensor switching
• Source/detection selection
• Research and development (R&D)
The JDSU SQ series optical switch is a highly flexible module with high optical
performance in latching or non-latching applications. The full feature set and
large number of optical configurations available in a common package and
interface make it ideal for a wide spectrum of applications.
The switch connects one or two channels to one of several (up to eight) channels.
Both single-mode (SM) and multimode (MM) versions are available. This switch
is also available in multi-pack configurations, for example 2 x 4, 2 x 6, 2 x 8 D
configuration (Duplex 1 x 2, 1 x 3, 1 x 4).
While in operation, the switch connects optical channels by using prisms to
redirect the signal from an input port into a selected output port. Using
collimating optics minimizes the insertion loss (IL) and improves the
repeatability and stability of the optical parameters. The switches are optically
passive, and therefore, are transparent to signaling formats.
Configurations can be manufactured for bi-directional performance as a factory option.

The common package may be ordered in optical configurations as follows:
• 1 x 3 up to 1 x 8
• 2 x 4, 2 x 6, 2 x 8 D configuration (Duplex 1 x 2, 1 x 3, 1 x 4)
• Dual 1 x 2
• SM or MM fiber
• 900 mm buffered fiber or 3 mm cable
All units are customer-configurable as:
• Latching
• Non-latching
• Default channel for non-latch operation
Electrical interfaces available include:
• 2 x 12 male header on the side
• 2 x 12 male (recessed) on the bottom (for PCB mounting)
The 2 x N configuration allows for mass reconfiguration of optical paths.
It provides simultaneous connections of 2 inputs to a number of outputs.
