可以使用前面板按键和数字键盘或通过GPIB和串行RS232接口来控制JDS Uniphase SB，SC和SCG系列台式/机架式可编程开关。SCG系列组合输入开关允许单个开关仪器替换多个开关元件，同时保持低损耗。在这一系列开关中，输入按特定顺序组合在一起，因此能够提供三种不同的操作模式（D，E和F配置）。
SB和SC系列开关有四种基本配置，即C，D，E和F。C配置是单个通用输入模型。D配置提供了一组输入光纤到输出光纤的同时连接。E配置允许将任何输入连接到任何输出，而将其他输入/输出对齐到后续/相邻通道。在此模式下，开关处于非阻塞状态，其他输入/输出对齐。F配置使输入之一与输出在阻塞的意义上对齐，从而减少了可用的输出通道。结果是一个低损耗的MxN阻塞开关。这些开关的操作基于JDS Uniphase久经验证的扩展光束透镜技术，该技术利用精密的步进电机对准光通道。使用准直透镜可最大程度地减少插入损耗，并提高可重复性和性能。开关机构的内部温度控制可确保出色的操作稳定性。
SB，SC和SCG系列交换机的单模和多模版本均可用。该系列具有研发和制造环境中多单元测试所需的高水平性能。紧凑的便携式SB交换机以及标准机架安装式外壳SC和SCG交换机非常适合电信，制造和测试环境中的应用。
JDS Uniphase的SB和SC开关因其低插入损耗和出色的可重复性而在光纤行业广为人知。除了可用的许多标准选项之外，我们还定制了本系列中的开关，以满足您的特定应用需求。
The JDS Uniphase 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 RS232 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 (D, E, and F configurations).
The SB and SC series switches are available in four basic configurations, namely C, D, E, and F. The C configuration is a single common input model. The D configuration provides simultaneous connection of a bank of input fibers to output fibers. The 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. The 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. A low-loss MxN blocking switch is the result. Operation of these switches is based upon JDS Uniphase's proven expanded beam lens technology, which utilizes a precision stepper-motor to align optical channels. The use of collimating lenses minimizes insertion loss and improves repeatability and performance. Internal temperature control of the switching mechanism ensures excellent operational stability.
Both single-mode and multimode 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 research and development and in manufacturing environments. The compact, portable SB switch and the standard rack-mount enclosure SC and SCG switches are highly suited for applications in telecommunications, manufacturing, and test environments.
JDS Uniphase's SB and SC switches are known in the fiberoptic industry for their low insertion loss and excellent repeatability. In addition to the many standard options available, we also customize switches in this series to meet your specific application need.
