Programmable Fibre Switches

JDSU / VIAVI SB Series Programmable Fibre Switches


The JDSU SB series of Benchtop Programmable Switches can be controlled using the front panel keys and a numeric pad or via GPIB and serial RS-232 interface.

The SB 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 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 is highly suited for applications in telecommunications, manufacturing, and test environments.

JDSU's SB Series 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.
