The NanoSpeed™ Series 1×4 solid-state fiber-optic splitter splits the optical power among four outputs with any power splitting ratio. The input is polarization-maintaining (PM) fiber and the outputs are four single mode or PM fibers. This is achieved using patent pending non-mechanical configurations with solid-state all-crystal designs, which eliminates the need for mechanical movement and organic materials, offering the ultra-long lifetime. The NanoSpeed™ fiber-optic switch is designed to meet the most demanding switching requirements of fast response time, and continuous switching operation. The switch is bidirectional.
