Applications
• Fiberoptic component testing and
measurement
• System testing
• Research and development (R&D)

of inputs/outputs with SCG series

• Connection of multiple wavelength
sources to any one of a number of
devices with SCG series (F configuration)
• Network monitoring
The JDSU SB, SC, and SCG series of Benchtop/Rackmount Programmable Switches
can be controlled using the front panel keys and a numeric pad or via GPIB and
serial RS-232 interface. The SCG series ganged input switches allow a single
switch instrument to replace multiple switch elements while maintaining low loss.
In this series of switches, the inputs are ganged together in a particular sequence
and are thus able to offer three different modes of operation.
The SB, SC, and SCG series switches are available in four basic configurations:
• C configuration - is a single common input model (SB, SC)
• D configuration - provides simultaneous connection of a bank of input fibers
to output fibers (SB, SC, SCG)
• E configuration - allows any input to be connected to any output while other
inputs/outputs are aligned to subsequent/adjacent channels. The switch is
non-blocking in this mode and other inputs/outputs are aligned (SB, SC, SCG)
• F configuration - enables one of the inputs to be aligned with an output in a
blocking sense, with a result in reduction of available output channels and a
low-loss M x N blocking switch. (SB, SC, SCG)
Operation of these switches is based upon JDSU's proven expanded beam lens
technology, which utilizes a precision stepper-motor to align optical channels.
The use of collimating lenses minimizes insertion loss (IL) and improves
repeatability and performance. Internal temperature control of the switching
mechanism ensures excellent operational stability.
Safety Information
• Complies to CE requirements plus
UL3101-1 and CAN/CSA-C22.2 No.

Continued
Both single-mode (SM) and multimode (MM) versions of the SB, SC, and SCG
series switches are available. The series features the high level of performance
required for multi-unit testing in R&D and in manufacturing environments. The
compact, portable SB switch and the standard rackmount enclosure SC and SCG
switches are highly suited for applications in telecommunications, manufacturing,
and test environments.
JDSU's SB, SC and SCG switches are known in the fiberoptic industry for their
low IL and excellent repeatability. In addition to the many standard options
available, we also customize switches in this series to meet your specific applica-
tion needs.
Configurations
1x N Switching: C Configuration (SB and SC)
The 1xN configuration allows a single common input to be switched to
any of the outputs.
Ganged Switching: D Configuration (SB/SC/SCG)
The MxN configuration allows for mass reconfiguration of optical paths.
It provides simultaneous connections of a bank of inputs to outputs, and
replaces several 1xN with single switch element.
Sequential Switching: E Configuration (SB/SC/SCG)
The MxN configuration aligns any input with any output, while other
inputs are aligned to adjacent outputs.
Blocking Switching: F Configuration (SB/SC/SCG)
The MxN configuration allows any one of a bank of inputs to connect
with any output with only one active connection at a time.
