General Information

This user’s manual for the SB Series Fiberoptic Switch contains complete operating instructions.

The SB Series 1xN programmable switches are designed to connect a single fiberoptic input channel to any of N (up to 48) output channels (Figure 1). The performance, configuration, flexibility, and portable enclosure are suitable for a wide range of applications, including fiberoptic component testing systems, remote fiber test systems in telecommunications, and research and development. Single-mode and multimode versions of the switches are available. The SB Series switches are bidirectional.

Figure 1: SB Switch

The SB switch connects the input to a selected output channel. The terminations are precisely aligned by a processor-controlled stepper motor. Collimating lenses terminate the fiberoptic attachments, minimizing the insertion loss of the switch and improving the repeatability and stability of its parameters.

The SB switch is equipped with IEEE 488.1 parallel and RS232 serial interfaces for remote operation. The switch also is operated manually using the front-panel controls. The switch status is displayed on the front-panel indicators.

The SB switch is available in single-common (SB-C) and dual-common (SB-D, SB-E, and SB- F) configurations. The dual-common units support two (paired) fiberoptic input channels.

Single-Common (SB-C) Switch Configuration

The common input channel (C) is connected to the output channel (1). The reset position (0) of the switch is an open circuit. This configuration is shown in Figure 2.
