SB/SC/SCG Series

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 and SC series switches are available in four basic configurations:

C configuration - is a single common input model
D configuration - provides simultaneous connection of a bank of input fibers to output fibers
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
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.

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.

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 and SC 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 application needs.
