Optical switch has an irreplaceable important role in all automated optical test system. It’s the core device to realize multiple objects testing and automated testing for various optical parameters, can avoid measurement uncertainty in multiple insertion and plug-pull of optical connectors.
Dimension offers a series of high-performance OSW optical switch modules for automation testing systems. These modules fit well in laboratories and in high standard manufacturing environments, applied together with Dimension's universal test platform, it can automatically route optical signals under program control, enabling parallel measurements for multiple optical channels and multiple optical components, significantly reducing the test time. So as to improve the total efficiency of testing procedures and reduce the overall cost.

Programmable, supports multiple trigger modes
OSW optical switch, can flexibly set the trigger modes of path switching by its program function. It can be triggered by external TRIG signal, waiting time, touchscreen, physical button or other modes, to provide various interfaces for the subsequent development of automation program.
OSW can reach 10 million times of random switch, MEMS optical switch can even reach to 1 billion times. The repeatability of insertion loss for 100 times random switch is less than 0.02dB, can provide users a high reliable optical path［1］
Low insertion loss, low polarization dependent loss, high channel consistency
Each channel the insertion loss is less than 1.0 dB, the polarization dependent loss is less than 0.05dB［2］
Platform + modular design, support multiple control modes
Dimension's universal test platform, is compatible with a wide range of functional test modules including OSW optical switches, offering significant advantages such as hot-pluggable, programmable, scalable, easy to maintain&manage, and low overall cost.

［1］ Lifetime of mechanical optical switch is longer than 10 million times , lifetime of MEMS switching life is longer than 1 billion times
［2］Excluding connectors. For mechanical optical switches the polarization dependent loss less than 0.05dB,for MEMS the polarization dependent loss less than 0.1dB.The insertion loss is related to the number of optical switch ports,The insertion loss of mechanical optical switches, is shown in the table below.。
［3］Depending on the number of optical switch ports, there is single-slot, dual-slot, and multi-slots, where the width of multiple slots is a superposition of single-slot widths.
