The benchtop instrument can switch up to two input fibers to any of up to eight output fibers, independently of data format, wavelength or optical power. The BS series optical switches are available either for single mode (SM) or multi mode (MM) fibers. The optical connections are set by a MEMS based switch network, where micromachined silicon mirrors redirect light to the selected ports. The use of MEMS technology offers solid state reliability together with long term stability and robustness for stable operation. The switch is controlled over an USB connection which also acts as power supply. BS series switches are built using Sercalo Microtechnology’s Telcordia-qualified MEMS technology, which achieves superior reliability and repeatability when compared to traditional mechanical solutions. The switches are fully bi-directional and transparent to the full wavelength range of the installed fiber. When several input fibers are required, the switch architecture can be either blocking or non-blocking. In the blocking architecture when one input is set, the other inputs can only be set to a limited number of “free” ports. In the non-blocking architecture there is no such limitation. Any of the input ports can go to any of the free output ports. But the complexity of the non-blocking architecture is much higher.
