Agilent/Keysight 86061C

The Keysight 86061C is a mid-size lightwave optical switch engineered for high-performance optical signal routing in test and measurement applications. This bi-directional switch accommodates single-mode fiber (9/125 µm) and multi-mode fibers (62.5/125 µm and 50/125 µm), with configurations supporting 1 or 2 input channels and up to 16 total output channels. A precision stepper motor mechanism delivers 10 million minimum switching cycles with repeatability down to ±0.005 dB between adjacent channels.
